I was able to get samples that play wav files and other to work, but the playsine app didn't work for me. I get the following error. I'm running gentoo on a quad-core. Any thoughts as to what I'm doing wrong here? I don't see a config file anywhere's that I'm missing. /pjproject-1.3/pjsip-apps/bin/samples/x86_64-unknown-linux-gnu$ playsine 2 23:37:23.128 os_core_unix.c pjlib 1.3 for POSIX initialized 23:37:23.198 pa_dev.c PortAudio sound library initialized, status=0 23:37:23.198 pa_dev.c PortAudio host api count=2 23:37:23.198 pa_dev.c Sound device count=14 23:37:23.198 pjlib select() I/O Queue created (0x2288ed8) 23:37:23.199 pa_dev.c PA message: Expression 'SetApproximateSampleRate( pcm, hwParams, sr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1291 23:37:23.199 pa_dev.c PA message: Expression 'PaAlsaStreamComponent_InitialConfigure( &self->playback, outParams, self->primeBuffers, hwParamsPlayback, &realSr )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1865 23:37:23.199 pa_dev.c PA message: Expression 'PaAlsaStream_Configure( stream, inputParameters, outputParameters, sampleRate, framesPerBuffer, &inputLatency, &outputLatency, &hostBufferSizeMode )' failed in 'src/../../../portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 1986 Unable to open sound device: Invalid sample rate [code=469996]
