| KotCzarny | it's useless, it will get dirty in no time | 00:25 |
| KotCzarny | it's either home pup or stinky pup | 00:26 |
| KotCzarny | also, skype worked on n8x0, so maybe it's the esd wrapper failing | 00:26 |
| DocScrutinizer05 | esd wrapper? | 00:27 |

| DocScrutinizer05 | o.O | 00:27 |

| KotCzarny | so unless it killed the daemon, it was using it | 00:28 |
| KotCzarny | hmm, which gives me an idea, he he | 00:28 |
| DocScrutinizer05 | well, they never got audio right, that's why I stopped betatesting their crap. Then I kicked it off all my devices when it started sucking on security and draining my N900 battery | 00:28 |
| endso | Hahaha thankfully he doesn't roll in the dirt or flop down in mud puddles .....So Kot ...no hope for gtkgep on the n8x0 then...odd I'd swear diablo turbo for sure already had esd ..I know it's in the ASUI | 00:28 |
| KotCzarny | endso, i didn't say my final word on that | 00:29 |
| endso | well there is a relief | 00:29 |

| KotCzarny | sure, no problem at all | 02:17 |
| KotCzarny | i'm hacking at the audio system though | 02:17 |
| KotCzarny | so far tried oss/esd combinations and all failed | 02:17 |
| *** louisdk has quit IRC | 02:17 | |
| KotCzarny | possible ways are gstreamer and alsa | 02:17 |
| KotCzarny | trying alsa now | 02:17 |
| endso | So you are attempting to get the device to record then...hm...alsa ..there is a good chance that will work better than esd...it is known to be a bit flaky on the n8x0 | 02:18 |
| *** louisdk has joined #maemo | 02:18 | |
| endso | esd that is | 02:19 |

| *** dreamer has joined #maemo | 02:20 | |
| *** vakkov has quit IRC | 02:22 | |
| DocScrutinizer05 | use ALSA | 02:26 |
| KotCzarny | doc, it's n8x0 | 02:26 |
| DocScrutinizer05 | so? | 02:26 |
| KotCzarny | so things are hairy there | 02:26 |
| KotCzarny | pity libao doesnt support recording | 02:27 |
| DocScrutinizer05 | dunno how they are hairy. I didn't check in depth | 02:27 |
| DocScrutinizer05 | anyway I'd consider PolypAudio more hairy than any ALSA | 02:27 |
| DocScrutinizer05 | and I'm relatively sure diablo came with ALSA like fremantle does | 02:29 |
| *** xes has joined #maemo | 02:30 | |
| KotCzarny | sure, but esd grabs it all for itself | 02:30 |
| DocScrutinizer05 | check if there's aplay/arecord (same binary) | 02:30 |
| KotCzarny | right now i'm writing c code to init alsa device | 02:30 |
| DocScrutinizer05 | yeah sure, all sound servers are crap, esd just like PA and phonon and ... | 02:31 |
| KotCzarny | wouldnt mind esd if it actually worked | 02:31 |
| DocScrutinizer05 | get aplay c code, it is the reference implementation | 02:31 |
| *** pentanol has joined #maemo | 02:32 | |
| DocScrutinizer05 | when there's a aplay/arecord binary on diablo, you're better off copying stuff from there rather than writing your own | 02:33 |
| KotCzarny | sure, but i have to hack it into other app | 02:33 |
| DocScrutinizer05 | that's ok | 02:33 |
| KotCzarny | which isn't always 1:1 | 02:33 |
| DocScrutinizer05 | well, for large parts it is | 02:33 |
| KotCzarny | devil is in details | 02:33 |
| DocScrutinizer05 | I know about such devilish details, I serviced the ALSA part of twinklephone | 02:34 |
| KotCzarny | do you know if i can open single stream for record and playback? | 02:35 |
| DocScrutinizer05 | sure | 02:35 |
| DocScrutinizer05 | you mean one for both? aka duplex? | 02:35 |
| KotCzarny | yes | 02:35 |
| DocScrutinizer05 | nah, afaik not | 02:35 |
| KotCzarny | fun. | 02:36 |
| KotCzarny | double initialization again | 02:36 |
| DocScrutinizer05 | you might reuse initialization, but you need to open one down stream and one up stream | 02:36 |
| DocScrutinizer05 | afaik | 02:36 |
| *** vakkov has joined #maemo | 02:37 | |
| DocScrutinizer05 | it's not like you could use same buffer concurrently for sending and receiving samples | 02:37 |
| KotCzarny | hmm, but i found this piece of code: snd_pcm_hw_params_set_access (aR, hw_params, SND_PCM_ACCESS_RW_INTERLEAVED); | 02:37 |
| KotCzarny | does it mean it can be used both ways? | 02:38 |
| DocScrutinizer05 | sorry, I don't know the ALSA interface specs by heart | 02:38 |
| DocScrutinizer05 | prolly yes, yet you can open it *either* for read *or* for write | 02:38 |
| DocScrutinizer05 | not for readwrite | 02:39 |

| KotCzarny | snd_pcm_open (&aP, argv[1], SND_PCM_STREAM_PLAYBACK, 0); | 02:42 |
| KotCzarny | second parameter is something in the way of "hw:0,0" ? | 02:42 |
| DocScrutinizer05 | sounds good | 02:43 |
| KotCzarny | not that much, can't guess names on n8x0 | 02:43 |
| DocScrutinizer05 | razher use e.g plughw:0,0 | 02:43 |
| DocScrutinizer05 | aplay -l, aplay -L | 02:44 |
| KotCzarny | no such commands | 02:44 |
| KotCzarny | diablo was castrated in the usual nokia's way | 02:44 |
| DocScrutinizer05 | that's a pity when there's no aplay | 02:44 |
| KotCzarny | gonna check diablo wheezy armel repo | 02:44 |
| DocScrutinizer05 | anyway there's only a few possibilities for soundcards: hw:0,0 hw:0,1 hw:1,0 hw:1,1 | 02:46 |
| DocScrutinizer05 | maybe 2 as well | 02:46 |
| KotCzarny | sure, unless it's nokia's os | 02:46 |
| KotCzarny | and there will be bazillion of different names | 02:46 |

| KotCzarny | pcm.!default is the name i have to use in both cases? | 02:49 |
| *** RzR is now known as rZr | 02:50 | |
| DocScrutinizer05 | default is used when you don't give any device | 02:52 |
| DocScrutinizer05 | but yes, you also could use default explicitly, I guess | 02:53 |
| DocScrutinizer05 | don't ask me about the ! I never understood what's the exact meaning | 02:53 |
| DocScrutinizer05 | anyway you'll find somewhere a pcm definition for e.g. pcm.stereo or whatever and it has sth like {rate=8000; slave default} | 02:56 |
| KotCzarny | nope | 02:56 |
| DocScrutinizer05 | and you probbaly will find a pcm.hw somewhere | 02:56 |

| KotCzarny | fun. | 03:03 |
| DocScrutinizer05 | the ! is illegal char I'd guess | 03:04 |

| KotCzarny | umkay, something is working | 03:05 |
| KotCzarny | i even get some feedback when tapping on the mic | 03:05 |

| *** andril has quit IRC | 03:13 | |
| DocScrutinizer05 | you need to free them too iirc | 03:14 |
| DocScrutinizer05 | just closing isn't enough | 03:14 |
| KotCzarny | sure, but now that app closed, how do i free them? | 03:15 |
| DocScrutinizer05 | or rather, closing might actually fail when you didn't free them beforehand | 03:15 |
| DocScrutinizer05 | good question, prolly reload the als kernel module | 03:15 |
| DocScrutinizer05 | dunno | 03:15 |
| KotCzarny | hehe | 03:15 |
| KotCzarny | reboot then | 03:15 |
| DocScrutinizer05 | what makes you think they are still open? | 03:16 |
| KotCzarny | [ 3808.617187] EAC mode: play enabled, rec enabled | 03:16 |
| KotCzarny | and no 'disabled' line in dmesg later on | 03:17 |
| KotCzarny | also, can't run app second time | 03:17 |
| DocScrutinizer05 | hmm | 03:17 |
| DocScrutinizer05 | no idea. actually that type alsa_dsp is new to me | 03:18 |
| KotCzarny | told you, it's hairy | 03:18 |
| DocScrutinizer05 | must be the kernel interface to ... dsp ;-) | 03:18 |
| KotCzarny | pity they couldn't write proper kernel device | 03:19 |
| KotCzarny | that would keep to standards and failsafe from user hackings | 03:19 |
| KotCzarny | yeah, it fails at snd_pcm_open | 03:20 |
| KotCzarny | so i can't even reset it without the reboot | 03:20 |
| DocScrutinizer05 | OpenMAX IL | 03:21 |
| KotCzarny | yeah, 'open' 'max' | 03:21 |
| KotCzarny | both lies | 03:21 |
| DocScrutinizer05 | http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Architecture/Multimedia_Domain | 03:21 |
| DocScrutinizer05 | it's prolly a TI thing | 03:21 |
| DocScrutinizer05 | DSP-bridge | 03:21 |
| KotCzarny | but you are reading n900's docs | 03:22 |
| DocScrutinizer05 | yes, but the OMAP2 isn't that much different in that regard | 03:22 |
| KotCzarny | it is, driver is worse | 03:22 |
| DocScrutinizer05 | afaik it also has a DSP | 03:22 |
| DocScrutinizer05 | and I guess alsa_dsp is ALSA's interface to OpenMAX IL or whatever the thing is called on OMAP2 | 03:24 |
| KotCzarny | ok, so how do i close the bastard properly? | 03:24 |
| KotCzarny | snd_pcm_drop ? | 03:24 |
| KotCzarny | then snd_pcm_close? | 03:24 |
| DocScrutinizer05 | unload the kernel module omap-dsp or whatever it's called | 03:25 |
| KotCzarny | nope | 03:25 |
| KotCzarny | builtin | 03:25 |
| DocScrutinizer05 | aah | 03:25 |
| DocScrutinizer05 | check source for aplay | 03:25 |
| DocScrutinizer05 | it's the reference inplementation | 03:25 |
| *** xorly has quit IRC | 03:27 | |
| KotCzarny | i think it just uses snd_pcm_close | 03:28 |
| KotCzarny | unless there is something to error handling | 03:29 |
| DocScrutinizer05 | as mentioned you need to free stuff before close will succeed | 03:30 |

| *** beford has joined #maemo | 03:36 | |
| KotCzarny | nah, it's just that author of the app didnt add snd stop func at all close cases | 03:36 |
| DocScrutinizer05 | sorry, can't help any further. That's the end of my alsa 'expertise' | 03:38 |
| KotCzarny | no worries, it almost works | 03:38 |
| KotCzarny | still have to hack at buffers (clicking etc) | 03:38 |
| DocScrutinizer05 | twinkle-1.1/src/audio/audio_device.cpp is about as much as I know about ALSA | 03:38 |
| DocScrutinizer05 | nice code | 03:39 |
| DocScrutinizer05 | I found the // Without the snd_pcm_hw_free, snd_pcm_close sometimes fails. | 03:39 |
| KotCzarny | i free hw just after init | 03:40 |
| DocScrutinizer05 | since nobody but me bothers to check error return code of a close() | 03:40 |
| KotCzarny | or not | 03:40 |
| *** dreamer has joined #maemo | 03:40 | |
| DocScrutinizer05 | and yes, ALSA docs suck in that they don't exlain when and how to use snd_pcm_hw_free() and *close() etc | 03:42 |
| *** louisdk has quit IRC | 03:46 | |
| DocScrutinizer05 | get twinkle-1.*/src/audio/audio_device.cpp it's probably pretty instructive particularly when you like OSS | 03:47 |
| KotCzarny | i'm tired a bit | 03:48 |
| KotCzarny | so for now i just install signal handler | 03:48 |
| DocScrutinizer05 | http://privatepaste.com/ece01709c6 | 03:49 |
| KotCzarny | i wouldnt call it simple interface | 03:49 |
| KotCzarny | but in my case it was the missing signal handler | 03:50 |
| KotCzarny | i'm amazed that kernel doesnt close the device on it's own... | 03:50 |
| KotCzarny | i guess that's the reason of n8x0's audio being flaky (sometimes works, sometimes not) | 03:50 |
| KotCzarny | can i catch -KILL ? | 03:53 |
| ZetaR | KotCzarny: SIGKILL cannot be caught. | 04:10 |
| KotCzarny | yeah. pity | 04:10 |
| ZetaR | Well, it does give you a way to kill a program that is hanging and refusing to respond to other signals. | 04:11 |
| KotCzarny | yeah, still, if i will ever have to kill this app via -KILL, audio device will be blocked | 04:12 |
| ZetaR | That... sounds like really poor design. | 04:14 |
| KotCzarny | on the nokia/ti, yes | 04:14 |
| ZetaR | You should immediately free resources when the blocking program gets killed. | 04:14 |
| *** Humpelst1lzchen has quit IRC | 04:16 | |
| *** Humpelstilzchen has joined #maemo | 04:17 | |
| ZetaR | Unfortunately, I don't really know much about OMAP and ALSA, so I can't really help you out. | 04:18 |
| KotCzarny | nah, as i've said, it was a missing signal handler, it's fixed now (to a point) | 04:19 |
| KotCzarny | do you know c? | 04:19 |
| ZetaR | Yeah, but not real experienced. | 04:20 |
| KotCzarny | process_buffer[i]>>=1; | 04:20 |
| KotCzarny | what does it do? | 04:20 |
| ZetaR | Hm, let me check K&R. Not sure what the >> is for. | 04:22 |
| KotCzarny | >> is bit shift | 04:22 |
| KotCzarny | but is >>= special? | 04:22 |
| ZetaR | Oh, well that sounds like you have an array and you are bit shifting and assigning a 1. | 04:23 |
| KotCzarny | o.o | 04:23 |
| KotCzarny | i wonder what the author meant by it.. | 04:23 |
| KotCzarny | but for shift you need param | 04:23 |
| KotCzarny | as in var>>2 etc | 04:23 |
| ZetaR | Hmm, maybe it is some other thing then. | 04:25 |
| ZetaR | According to K&R, most of the binary operators have a corresponding assignment operator, which is what >>= is. So that line should be equivalent to "process_buffer[i] = process_buffer[i] >> 1;" | 04:30 |
| KotCzarny | uhum | 04:30 |
| ZetaR | "expr1 op = expr2" is equivalent to "expr1 = (expr1) op (expr2)" | 04:31 |
| KotCzarny | i still don't know what app author wanted to achieve, because it only shifts by 1 bit then overwrites it next | 04:31 |
| ZetaR | Unfortunately, K&R does not contain the necessary rituals for divining the intentions of other programmers. | 04:32 |
| KotCzarny | http://pastebin.com/raw.php?i=miq1Ty4j | 04:33 |
| KotCzarny | this is the part of the code | 04:33 |
| KotCzarny | ignore <---> | 04:33 |
| KotCzarny | process_buffer is audio data, 2ch, 16bit samples | 04:34 |
| ZetaR | That doesn't overwrite it. | 04:34 |
| KotCzarny | if i read it correctly, it overwrites one channel with the other shifted by one bit | 04:34 |
| ZetaR | Oh, I thought you meant it overwrites it uselessly. | 04:35 |
| KotCzarny | process_buffer data type is short | 04:36 |
| ZetaR | So it shifts the samples in the array by one, and bitshifts the samples by one? | 04:37 |
| KotCzarny | it's late, i might be wrong/blind | 04:37 |
| ZetaR | Sorry, I need to go AFK for ~30min. | 04:37 |
| KotCzarny | no worries | 04:37 |

| DocScrutinizer05 | hey, that divides by two (>>1) and copies left into right chan | 05:01 |
| KotCzarny | yeah, that's why i don't understand it | 05:01 |
| DocScrutinizer05 | which makes sense since stereo->mono later on adds both channels and thus compensates for the divide by 2 aka rightshift | 05:02 |
| KotCzarny | huh? | 05:02 |
| KotCzarny | so it's primitive stereo->mono code? | 05:02 |
| DocScrutinizer05 | it's prolly mono isgnal in left chan of a stereo stream | 05:02 |
| DocScrutinizer05 | this code copies left chan into right chan so it's balanced stereo, and compensates for the volume increase that causes | 05:03 |
| KotCzarny | what do you mean by 'balanced stereo' | 05:04 |
| DocScrutinizer05 | it's rather mono->stereo | 05:04 |
| DocScrutinizer05 | input is L?L?L?, output is (L/2)(L/2)(L/2)(L/2)(L/2)(L/2) | 05:05 |
| DocScrutinizer05 | ? is probably 0 | 05:05 |
| DocScrutinizer05 | or bogus data | 05:05 |
| KotCzarny | i could understand that it overwrites right chan with quited left chan | 05:06 |
| DocScrutinizer05 | a correct stereo input would be LRLRLR | 05:06 |
| DocScrutinizer05 | looks like what I'd do to a headset mic input | 05:07 |
| KotCzarny | unless your mic input is really stereo | 05:07 |
| DocScrutinizer05 | which per definition is on left channel when input is stereo | 05:07 |
| KotCzarny | or if input is line-in | 05:07 |
| DocScrutinizer05 | never seen a headset with stereo mic :-) | 05:08 |
| KotCzarny | this app comes from desktop | 05:08 |
| KotCzarny | but ok, thanks for helping me understand the author | 05:08 |
| DocScrutinizer05 | it copies left into right channel and attenuates both by 50% | 05:09 |
| KotCzarny | yeah | 05:09 |
| KotCzarny | now i have to tidy up the block sizes he uses | 05:09 |

| bencoh | freemangordon: http://tools.ietf.org/html/rfc6120#section-4.6 (xmpp keepalive) | 21:34 |
| *** arossdotme-nolog has joined #maemo | 21:36 | |
| freemangordon | bencoh: so you think both fb and gtalk send keepalives? | 21:38 |
| bencoh | either the server or the client, yes | 21:38 |
| bencoh | most likely the client | 21:38 |
| freemangordon | hmm, that might explain the "no more than a day" case | 21:38 |
| bencoh | I think they cut the session if they dont receive it | 21:39 |
| KotCzarny | http://stackoverflow.com/questions/7967585/how-does-facebook-chat-tcp-connection-keep-alive | 21:39 |
| bencoh | (hmm I usually dont let ssh run all day long btw) | 21:40 |
| freemangordon | well, but on the other hand - I don;t believe such keepalives are send that often | 21:40 |
| bencoh | I'd say one every minute | 21:40 |
| freemangordon | which is not that much | 21:40 |
| bencoh | hm yeah, not that much | 21:40 |
| KotCzarny | freemangordon, let it idle for 1h, and compare /proc/*/net/* counters | 21:40 |
| bencoh | but I enabled it for ssh once (shitty internet uplink with tcp timeout) and battery decreased more quickly | 21:41 |
| freemangordon | or rather run tcpdump for 10 minutes :) | 21:41 |
| bencoh | yeah :) | 21:41 |
| KotCzarny | that would work too | 21:41 |
| freemangordon | bencoh: define "more quickly" | 21:42 |
| bencoh | unfortunately I didnt keep track of the numbers | 21:42 |
| freemangordon | well, subjectively | 21:42 |
| KotCzarny | or: freemangordon, don't use facebook for one day | 21:43 |
| KotCzarny | ;) | 21:43 |
| bencoh | but it was like "oh hey, 20% just disappeared in 2h" or something like that | 21:43 |
| freemangordon | oh | 21:43 |
| bencoh | (ssh from my computer to the n900) | 21:43 |
| bencoh | (wireless) | 21:44 |
| freemangordon | KotCzarny: i will have to disable both fb and gtalk | 21:44 |
| KotCzarny | freemangordon: do it | 21:44 |
| KotCzarny | :) | 21:44 |
| freemangordon | though, I am going to WOA in 10 days, I guess I can use the time I'll be there to disconnect from the social networks and chats :) | 21:45 |
| bencoh | freemangordon: irssi+bitlbee (or the other xmpp/irc gateway .. forgot the name) over ssh ? 0:) | 21:45 |
| *** rm_work is now known as rm_work|away | 21:45 | |
| bencoh | oh you're actually dropping fb/gtalk for real forever ? | 21:45 |
| freemangordon | no | 21:45 |
| freemangordon | just 4 days while I'll be in Germany :) | 21:46 |
| bencoh | :) | 21:46 |
| freemangordon | ~woa | 21:46 |
| bencoh | ~google woa | 21:46 |
| bencoh | ~search woa | 21:47 |
| bencoh | meh :) | 21:47 |
| freemangordon | ~WOA is Wacken Open Air | 21:47 |
| infobot | freemangordon: okay | 21:47 |
| bencoh | haha | 21:47 |
| freemangordon | anyway, with ~80000 people on a couple of cells, I doubt there will be much of a connectivity :D | 21:48 |
| bencoh | haha | 21:49 |
| KotCzarny | microwavefest | 21:49 |
| bencoh | yeah, best to just switch to offline mode | 21:49 |
| bencoh | KotCzarny: ear damages werent enough 0:) | 21:49 |
| freemangordon | well, not offline, but disconnected from internet | 21:50 |
| *** _rd has joined #maemo | 21:50 | |
| freemangordon | I guess there'll be no need to charge | 21:50 |
| bencoh | yeah, it should last 5 days with no connectivity | 21:51 |
| bencoh | hmm, maybe not, that's if you keep it in your pocket and dont really use it | 21:51 |
| freemangordon | will see | 21:51 |
| bencoh | and .... shit ... I forgot mtr running since yesterday ... again. :D | 21:52 |
| bencoh | that's the one battery killer I always forget about | 21:52 |
| vectis | ~/MyDocs/.sounds $ mplayer -ao alsa:device=hw=1.0 Moby-In_My_Heart.mp3 ->> alsa-lib: pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM hw:1,0 | 21:52 |
| freemangordon | mtr is? | 21:52 |
| bencoh | https://en.wikipedia.org/wiki/MTR_(software) (traceroute) | 21:53 |
| freemangordon | oh | 21:53 |
| KotCzarny | vectis: can you show /proc/asound/cards | 21:53 |
| bencoh | much better than traceroute, really handy | 21:53 |
| KotCzarny | yeah | 21:53 |
| KotCzarny | bencoh, but they return different results sometimes | 21:54 |
| bencoh | KotCzarny: indeed | 21:54 |
| bencoh | and ... with slow/lossy networks and strange uplinks/backbones it can make it easier to get a tcp/ssh session open ... dont ask me why | 21:54 |
| KotCzarny | because it keeps celltower awaken | 21:55 |
| KotCzarny | ie. not freeing timeslot | 21:55 |
| vectis | 1 [Audio ]: USB-Audio - USB Audio C-Media INC. USB Audio at usb-musb_hdrc-1.4, full speed | 21:55 |
| bencoh | maybe | 21:55 |
| KotCzarny | similar efect with ping -s8 8.8.8.8 | 21:55 |
| freemangordon | KotCzarny: on 2G? I doubt | 21:55 |
| freemangordon | there are no dedicated slots for data on 2G iirc | 21:56 |
| bencoh | I suspect it involves some terrible routing table management | 21:56 |
| KotCzarny | freemangordon: tested and tried, ping every 1s and it's much better for ssh | 21:56 |
| freemangordon | KotCzarny: again, on 2G or 3G? | 21:56 |
| bencoh | s/routing table/FIB (forwarding information base/table) on some routers/l3-switches | 21:56 |
| freemangordon | KotCzarny: also, remember there is iphbd running on n900 ;) | 21:56 |
| bencoh | iphbd ? | 21:57 |
| freemangordon | ~iphb | 21:57 |
| freemangordon | ~iphbd | 21:57 |
| KotCzarny | freemangordon: no matter, when i need interactivity i just run ping in the background (-s8 to keep is small datawise) | 21:57 |
| KotCzarny | vectis: /proc/asound/devices ? | 21:57 |
| freemangordon | bencoh: IP heartbeat daemon or somesuch | 21:58 |
| bencoh | wow, I never noticed it running | 21:58 |
| vectis | 0: [ 0] : control 32: [ 1] : control 33: : timer 48: [ 1- 0]: digital audio playback | 21:58 |
| KotCzarny | hmm, it should work as 1.0 then | 21:59 |
| freemangordon | afaik it delays data transmission until a timeout has expired or there is enough data to be send, thus preventiong radios from waking up too often | 21:59 |
| freemangordon | bencoh: ^^^ | 21:59 |
| bencoh | hmm | 22:00 |
| bencoh | it might be just that then | 22:00 |
| bencoh | sounds a bit silly but ... | 22:00 |
| bencoh | I guess a poor single tcp syn just wouldnt have any chance alone | 22:00 |
| bencoh | is it opensource ? | 22:01 |
| freemangordon | no :D | 22:01 |
| bencoh | shit :D | 22:01 |
| freemangordon | but there is dbus iface | 22:01 |
| bencoh | haha | 22:01 |
| freemangordon | http://wiki.maemo.org/N900_dbus#com.nokia.iphbd | 22:01 |
| bencoh | thx | 22:01 |
| freemangordon | look at the header | 22:01 |
| bencoh | http://www.cncmods.net/files/dbus/libiphb.h woooh | 22:01 |
| bencoh | hmm | 22:02 |
| freemangordon | there is also a kernel module (FOSS) iirc | 22:02 |
| bencoh | looks like you explicitly need to use it | 22:02 |
| bencoh | oh | 22:02 |
| freemangordon | https://github.com/nemomobile/libiphb/tree/master/src | 22:03 |
| freemangordon | seems it has been open-sourced after all | 22:04 |
| bencoh | neat | 22:04 |
| bencoh | wonder if telepathy/rtcom-messaging makes use of it | 22:05 |
| freemangordon | I'd bet on that | 22:06 |
| KotCzarny | vectis, btw. is there /dev/dsp file? (ignore /dev/dsptask*) | 22:06 |
| freemangordon | bencoh: seem nemomobile iphbd has some differences compared to maemo, but I wonder if I should arm IDA and RE it, should be pretty much easy task with all those headers and source code around | 22:07 |
| *** Ras_Older has quit IRC | 22:07 | |
| KotCzarny | freemangordon: do it | 22:08 |
| vectis | yer, dsp1 | 22:09 |
| KotCzarny | vectis: http://pastebin.com/raw.php?i=ikt2FUUq | 22:09 |
| KotCzarny | put contents into ~/.asoundrc | 22:09 |
| KotCzarny | then try mplayer -ao alsa some.mp3 | 22:09 |
| freemangordon | KotCzarny: on the other hand - why noone else want to do RE work? It is not *that* hard! | 22:12 |
| freemangordon | *wants | 22:12 |
| bencoh | freemangordon: it doesnt look like a critical part of maemo, but well if you have some time :) | 22:12 |
| KotCzarny | freemangordon: it is for someone who doesn't have tools/knowledge/experience | 22:13 |
| * freemangordon looks for volunteers to do RE job, with my help :) | 22:13 | |
| KotCzarny | freemangordon: make a wiki thread | 22:13 |
| KotCzarny | i mean tmo thread | 22:13 |
| freemangordon | KotCzarny: hmm, might work | 22:13 |
| *** eMHa__ has joined #maemo | 22:14 | |
| KotCzarny | on another note, my usb audio card claims to suck 500mA, yet, usb meter only shows ~30mA | 22:14 |
| KotCzarny | now i need some gender bender for my n800 | 22:14 |
| freemangordon | KotCzarny: connect headphones to it and raise the volume up | 22:14 |
| freemangordon | low-resistance ones | 22:15 |
| KotCzarny | i've connected it to stereo box | 22:15 |
| KotCzarny | but i know that it can eat more | 22:15 |
| freemangordon | that is why only 30 mA | 22:15 |
| KotCzarny | still, nice to know i can connect it to n800 and use as a grabber card | 22:15 |
| KotCzarny | without external power | 22:16 |
| freemangordon | doesn't it require CPU resources? | 22:16 |
| KotCzarny | dont know, what for? | 22:16 |
| KotCzarny | i mean, apart from data moving | 22:17 |
| *** SpeedEvil has quit IRC | 22:17 | |
| vectis | hmm, do I need to reboot? | 22:18 |
| KotCzarny | vectis, nope | 22:18 |
| freemangordon | no idea, I am under impression USB is not the most effective when it comes to low CPU usage | 22:18 |
| vectis | still no go........... | 22:18 |
| KotCzarny | vectis, same error msg? | 22:19 |
| vectis | yer | 22:19 |
| bencoh | freemangordon: I'm writing assembly on a DSP at $NEWJOB (2 weeks) so I might be of some help with RE-ing stuff and asm after some time :) | 22:19 |
| KotCzarny | freemangordon: yeah, and it's usb1, still, working solution is better than non working low power solution | 22:19 |

| freemangordon | bencoh: C64+? O.o | 22:20 |
| bencoh | freemangordon: hm no | 22:20 |
| freemangordon | wait, wait, why assembly? | 22:20 |
| bencoh | because ... there is no C compiler for our target :D | 22:21 |
| freemangordon | omg :D | 22:21 |
| bencoh | (small/specific embedded) | 22:21 |
| freemangordon | what an exotic piece of silicon is that? | 22:21 |
| freemangordon | if not under NDA ofc :) | 22:22 |
| KotCzarny | vectis: don't forget to remove that .asoundrc file, it can interfere with the system | 22:22 |
| bencoh | I'm afraid it is (full specs arent public and it's not in our product description either) :( | 22:22 |

| freemangordon | hmm, I thought that all 2.6.x kernels have NPTL | 23:16 |

| freemangordon | Luke-Jr: ^^^ | 23:19 |
| Luke-Jr | freemangordon: well, glibc 2.20 apparently begs to differ and won't work with <2.6.32 :/ | 23:20 |
| *** KotCzarny has quit IRC | 23:20 | |
| freemangordon | afaik it is bacause the kernel misses other things that glibc needs | 23:21 |
| freemangordon | *because | 23:21 |
| *** KotCzarny has joined #maemo | 23:22 | |
| L29Ah | i removed the check and it crashes :3 | 23:22 |
| L29Ah | the previous version works afair | 23:23 |
| Luke-Jr | 2.19 crashes for me :/ | 23:23 |
| freemangordon | but why did you decide it is NPTL that is the problem? | 23:23 |
| Luke-Jr | "You need a kernel of at least 2.6.32 for NPTL support!" | 23:26 |
| freemangordon | well, that sounds like 2.20 requires some features in 2.6.32 to enable NPTL, but doesn't sound like there is no NPTL support in 2.6.28 | 23:28 |
