MNZWhat's Line Output Plus/Minus Control ?00:00
DocScrutinizerwhatthehelleverthatmightmean00:00
DocScrutinizersounds like differential or inverted phase related00:00
DocScrutinizer# IHF and headset00:02
DocScrutinizerihfandheadset    = @outband_cancellation@00:02
DocScrutinizerihfandheadset    = @outband_cancellation@00:02
MNZI Headphone Filter00:02
DocScrutinizerSIC! now if that's no bug or at least flaw00:02
DocScrutinizerwell, to me it seems alsaped is some kind of a(lsa)mixer 'replacement', with d-bus interface instead UI, and some weird obscured way to have 'presets' that allow setting several control elements with a single command00:08
MNZhrm so something else is picking up on the changes and doing the 'context reuest' ?00:10
MNZlemme kill PA00:10
MNZyup it's PA00:11
MNZkilled PA, no more context reuests00:11
MNZso alsaped sits there with its presets waiting for someone to tell it to reuest a change00:12
MNZhow do we snoop on dbus messages?00:13
DocScrutinizerMNZ: dbus-monitor --system; dbus-momitor --session;00:19
DocScrutinizerMNZ: or mdbus2 --help00:19
MNZthat's a lot of shit for plugging in the headphone00:21
DocScrutinizerthough on listening dbus-monitor is more verbose00:21
MNZno wonder it takes a second or two to register00:21
DocScrutinizerthan mdbus200:21
DocScrutinizerbut mdbus2 is great on tab-expanding dbus method/system pathes00:22
DocScrutinizerwhich dbus-send doesn't know at all00:23

MNZsignal sender=:1.9 -> dest=(null destination) serial=1433 path=/org/freedesktop/Hal/devices/platform_headphone; interface=org.freedesktop.Hal.Device; member=PropertyModified00:31
MNZmdbus2 :1.9   =  /00:32
MNZdoes a program need to register with the dbus interface if it just wants to listen to certain signals?00:36
DocScrutinizeryes01:19
DocScrutinizerafaik01:20
DocScrutinizerI'd think usually the interface is a good hint01:20
DocScrutinizerinterface=org.freedesktop.Hal.Device01:21
DocScrutinizerpath as well, it suggests sender if this signal was HAL01:23
MNZthe one that's interesting me more is signal sender=:1.92 -> dest=(null destination) serial=64 path=/org/kernel/class/input/input16; interface=org.kernel.kevent; member=add01:24
DocScrutinizerwhich easily might be correct01:24
DocScrutinizerdunno if kernel is supposed to send dbus signals by itself :-S01:24
MNZI highly doubt it :D01:25
DocScrutinizerit's a kevent obviously, so means kernel emitted a sysfs related signal to any process that registered for it using uevent - aiui01:26
MNZit should be possible to see what signals a certain prog listens for by watching out for calls to libdbus, correct?01:26
DocScrutinizerthere's probably some listener to kevents that sends dbus events when it receives kevents01:27
DocScrutinizernope, I don't think so. probably each process listening to any signal on dbus will get an activation on this lib function when a arbitrary dbus signal is sent. But honestly I'm talking out of my ass, I got no clue about dbus01:28
MNZI have no clue either D: off to #dbus then01:29
MNZbut before pursuing this any further... why are we doing this again?01:29
SpeedEvilarbitrarily being able to stop signals would be good.01:34
MNZ<thiago_home> no, there's no way to do that with D-Bus01:37
MNZ<thiago_home> you have to watch the program from its start and guess what signals it's listening by the AddMatch calls it makes01:37
MNZthe process doing the kevent broadcasting is /usr/sbin/hulda01:40

MNZke-recv-extra: Program for receiving low-memory events from the kernel and forwarding them01:43
MNZ to the D-Bus system bus, etc. Kimmo Hämäläinen <kimmo.hamalainen@nokia.com>01:43
MNZhow would I intercept shared library calls from PA and see what's happening? gdb the only way?01:45

lcuklbt, the giants causeway has many pillars who could make this union of openness visual02:11
lcukand a load of us are going near there in a few weeks ;)02:12
lcukwould be great to flood that with media and spool it together02:13

ShadowJK"ltrace is a program that simply runs the specified command until it exits.  It intercepts and records the dynamic library calls which are called by the executed process and the signals which are received by that process.  It can also intercept and print the system  calls  executed by the program."02:15
