I wrote a short script to test my sound devices. Trying to set_snd_device to (0,0) creates error messages. Here?s the script: http://pastebin.com/bN7Sc8q8 And here?s the output: http://pastebin.com/vukWV4UP I am able to set it use lib.set_snd_dev(9,9) without complaint, but obviously there?s no sound, and it seems to hang the library? trying to set it to 10,10 (dmix) creates even more error messages. Here?s the output of aplay ?l: card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 Do I need to mess with alsa config? Pjsua is able to figure out the right thing to do on it?s own. What am I missing in the python? --Travis From: Travis LaDuke [mailto:travis.laduke@xxxxxxxxxxxxx] Sent: Wednesday, October 17, 2012 3:53 PM To: 'pjsip at lists.pjsip.org' Subject: Python alsa errors I?m having trouble connecting the a call to a my sound device with the python lib. I?m not sure if something didn?t get installed or if my script is wrong or if I need to configure alsa more. When I call make_call(), I get: Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1294 Expression 'PaAlsaStreamComponent_InitialConfigure( &self->capture, inParams, self->primeBuffers, hwParamsCapture, &realSr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1870 Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1994 Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1294 Expression 'PaAlsaStreamComponent_InitialConfigure( &self->capture, inParams, self->primeBuffers, hwParamsCapture, &realSr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1870 Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1994 Then when I destroy.lib() I get: python2: ../src/pjmedia-audiodev/audiodev.c:682: pjmedia_aud_dev_default_param: Assertion `aud_subsys.pf' failed. [1]??? 2222 abort (core dumped)? python2 pjsip.py I can see the call come in to Asterisk and Asterisk plays a sound file, but obviously I don?t hear it on my speaker. pjsua is able to send/receive audio and I don?t give it any specific audio configuration. I?m a little confused about the files it is complaining about up there. They don?t exist on my system except in the build directories. What should I look at next? -- Travis
