Hi: Well, I started every every thing and with rev 1848: 1. assertion on PA callback: pj_assert(frameCount == stream->samples_per_frame * stream->channel_count); This bug has been fixed (see http://trac.pjsip.org/repos/ticket/504). And that works, now, I'm having the other problem: root at h3900:~/bin# ./sndinfo-arm-unknown-linux-gnu 0 both 44100 2 16 02:03:59.954 os_core_unix.c pjlib 0.8.0-trunk for POSIX initialized 02:03:59.980 pasound.c PortAudio sound library initialized, status=0 02:03:59.980 pasound.c PortAudio host api count=1 02:03:59.980 pasound.c Sound device count=1 02:03:59.981 pjlib select() I/O Queue created (0x3d7f4) Opening device 0 for capture/playback: clockrate=44100, nchannel=2, bits=16, nsamples=882.. 02:03:59.999 pasound.c PA message: Expression 'ioctl( component->fd, SNDCTL_DSP_SETFRAGMENT, &frgmt )' failed in 'src/../../../portaudio/src/hostapi/oss/pa_unix_oss.c', line: 1023 sndinfo-arm-unknown-linux-gnu: src/../../../portaudio/src/hostapi/oss/pa_unix_oss.c:1124: PaOssStream_Configure: Assertion `component->hostChannelCount > 0' failed. Aborted What I think is that it cannot use that hardware in dubplex mode.... something like that but not for sure. Is there another alternative??? -------------- next part -------------- An HTML attachment was scrubbed...
