microphone doesn't work with skype about apulse HOT 19 CLOSED

If you launch Skype from terminal emulator, do you see any error messages?

from apulse.

No.

Then I have no idea what it is and how to fix it.

Any ideas about how to debug it? Increase debug level, use strace, etc.?

from apulse.

Also, I've previously used skype with pulseaudio, and used pavumeter to configure it, so maybe this happens because of some leftovers of pulseaudio configuration?

Any ideas about how to debug it?

Compiling debug version will turn on trace output, for almost every API call will be printed to stdout. (cmake -DCMAKE_BUILD_TYPE=Debug .., then make again.)
I would trace return values from ALSA calls. Now if one of them fails, error is reported. It's still odd that no errors messages was produced.

Then, I would probably add logging to capture path to find out if any data is read from device.

so maybe this happens because of some leftovers of pulseaudio configuration?

No, I don't think so.

I've run /usr/bin/i686-pc-linux-gnu-apulse skype >apulse-debug.log 2>&1 (yesterday's dev version, I don't have ~/.asoundrc now), make skype test call, and exit skype. Please check log http://powerman.name/tmp/apulse-debug.log and let me know what I should try next.

try to edit ~/.asoundrc like that:

pcm.usb
{
type hw
card Audigy2
}

pcm.!default
{
type asym
playback.pcm
{
type plug
slave.pcm "dmix"
}
capture.pcm
{
type plug
slave.pcm "usb"
}
}

@lodgerz thanks, but it makes no difference, except with your .asoundrc skype was unable to open sound device while mplayer was runnning (without .asoundrc this issue doesn't exists).

from apulse.

show me the output of:
$ cat /proc/asound/cards

from apulse.

$ cat /proc/asound/cards

With both configs microphone in skype still doesn't work.
With second config I've also tried to run skype while mplayer was running - works ok - and also tried again to use arecord/aplay - microphone in arecord works ok:

$ LANG=C arecord -t wav -r 44100 -f S16_LE 1.wav
Recording WAVE '1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
^CAborted by signal Interrupt...
arecord: pcm_read:2031: read error: Interrupted system call
$ aplay 1.wav 
Playing WAVE '1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono

I've also tried -r 48000 - works ok too. Not sure is this important but by default (without params) arecord use very bad quality (but it also works ok): "Unsigned 8 bit, Rate 8000 Hz, Mono".

from apulse.

BTW, looks like there is no difference in running skype or apulse skype because in Gentoo apulse's libs are installed into /usr/lib64/ and /usr/lib32/ and these paths are already in /etc/ld.so.conf.

Is there exists small tool similar to arecord but which use pulseaudio, to test microphone+apulse without skype?

Is there exists small tool similar to arecord but which use pulseaudio, to test microphone+apulse without skype?

avconv -f pulse -i default out.wav (or ffmpeg -f pulse -i default out.wav)

but they don't work now. Functions in libpulse-simple.so are not implemented, and if I use libpulse-simple.so from PulseAudio, nothing gets recorded. Didn't investigate that.

@powerman, try code from https://github.com/i-rinat/apulse/tree/dev

from apulse.

@i-rinat wow, it works! Thanks!

OK, pushed to master branch.
