Hey people, I hope I'm in the right place bothering all of you, but I need some help with getting a little project going. Background: I'm trying to connect my apartments door intercom to a USB soundcard and then be able to connect to it when someone rings the door. I've hit a somewhat significant issue tho: I was able to compile pjproject 2.1.0 without a hiccup, but there are several issues interfacing with the soundcard. First of all, there's zero audio. You can tell there is a change in status when pjsua is started because of slight noise setting in, but in-call there's nothing but silence, the call being ended because of inactivity after a bit. Testing it with the onboard audio output, there actually is (Very quiet and bad) audio being transmitted. When a call is ended, I always get this and the program seems to hang somewhat: 23:16:10.115 pjsua_aud.c .Closing USB Audio Device: USB Audio (hw:1,0) sound playback device and USB Audio Device: USB Audio (hw:1,0) sound capture device I can play wav's fine through aplay. pjsystest's "Play Tone" also works, with the hang I described above occuring. When I use the "Device Test" I get the following: 1 23:22:54.598 systest.c Running Audio Device Test 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 Unable to open device: Invalid sample rate (err=469996) Error Sorry we encountered error with the testInvalid sample rate If anyone can help me out here, I'd really appreciate it greatly!

Why 2.1.0 and not a newer version? Also: what software do you run on that system? Rapsbian?
