Hi I had the same problem on Raspberry PI. It solved by doing the following steps: Edit the config_site.h file at "../pjlib/include/pj/" and write these lines in it: #define PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO 0 #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1 #include <pj/config_site_sample.h> ./configure make clean make dep make I hope this maybe helpfull From: pjsip [mailto:pjsip-bounces@xxxxxxxxxxxxxxx] On Behalf Of Tanny Sent: Monday, January 04, 2016 1:15 AM To: pjsip at lists.pjsip.org Subject: Beaglebone Black Rev-C with C-Media USB audio, no sound The audio problem - a total lack of sound - occurs when attempting to use pjsip to connect two Beaglebone Black Rev-C boxes on a LAN, running Debian from microSD cards. There is no NAT issue since both are inside the same LAN. Orange Box: =========== Linux cargo-42-4 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux Debian GNU/Linux 7 The IP Address for eth0 is: 192.168.1.32 C-Media USB audio (nameless cheapo) Transparent Box: ================ Linux cargo-159 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55 UTC 2015 armv7l GNU/Linux BeagleBoard.org Debian 7.9 Image 2015-11-12 The IP Address for eth0 is: 192.168.1.15 C-Media USB audio (Syba) Both boxes can record ('arecord') and play ('aplay') audio properly over the USB dongle, which is the default audio device (.asoundrc == 'pcm.!default sysdefault:Device'). HDMI audio is fully disabled via uEnv.txt. The problem is that when connected via pjsip 2.4.5, no sound is communicated, and no port 4000 UDP packets are transferred. A pjsua recording test yields an empty wav file. Test: ===== I run pjsua on both boxes, then initiate a call from Orange Box to Transparent Box. Some errors occur when opening the sound device (but maybe they're legitimate codec-match failures). The next console snippet shows all the errors that occur (captured from Orange Box, but both boxes behave the same). ===== 11:06:39.410 pjsua_aud.c .Set sound device: capture=-1, playback=-2 11:06:39.411 pjsua_app.c ..Turning sound device ON 11:06:39.412 pjsua_aud.c ..Opening sound device PCM at 16000/1/20ms 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 11:06:39.430 pjsua_app.c ..Turning sound device ON 11:06:39.432 pjsua_aud.c ..Opening sound device PCM at 44100/1/20ms 11:06:39.489 ec0x236770 ...AEC created, clock_rate=44100, channel=1, samples per frame=882, tail length=200 ms, latency=0 ms ===== Some INVITES later, the media negotiation looks good: ===== 11:06:45.382 pjsua_core.c .RX 885 bytes Response msg 200/INVITE/cseq=22258 (rdata0x24cebc) from UDP 192.168.1.15:5060: SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.1.32:5060;rport=5060;received=192.168.1.32;branch=z9hG4bKPjl0nsfaVcpIDXP9f9jS1bzxPnA.zg2QjS Call-ID: Odd58LgI.B2F2WUfW.RmbTox2CXzpAK7 From: <sip:192.168.1.32>;tag=-HgPab8XCkf0D3cnQxggXsmhX-IJaFur To: <sip:192.168.1.15>;tag=BV9GhxaJGo5ihz.yt5SbQHkX3cbMmCJV CSeq: 22258 INVITE Contact: <sip:192.168.1.15:5060> Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE, INFO, SUBSCRIBE, NOTIFY, REFER, MESSAGE, OPTIONS Supported: replaces, 100rel, timer, norefersub Session-Expires: 1800;refresher=uac Require: timer Content-Type: application/sdp Content-Length: 275 v=0 o=- 3660836799 3660836800 IN IP4 192.168.1.15 s=pjmedia b=AS:84 t=0 0 a=X-nat:0 m=audio 4000 RTP/AVP 98 96 c=IN IP4 192.168.1.15 b=TIAS:64000 a=rtcp:4001 IN IP4 192.168.1.15 a=sendrecv a=rtpmap:98 speex/16000 a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-16 --end msg-- 11:06:45.407 pjsua_app.c .....Call 0 state changed to CONNECTING 11:06:45.410 pjsua_media.c .....Call 0: updating media.. 11:06:45.411 pjsua_aud.c ......Audio channel update.. 11:06:45.414 strm0x2d6034 .......VAD temporarily disabled 11:06:45.419 strm0x2d6034 .......Encoder stream started 11:06:45.420 strm0x2d6034 .......Decoder stream started 11:06:45.424 pjsua_media.c ......Audio updated, stream #0: speex (sendrecv) 11:06:45.426 pjsua_app.c .....Call 0 media 0 [type=audio], status is Active 11:06:45.428 pjsua_aud.c .....Conf connect: 4 --> 0 11:06:45.429 conference.c ......Port 4 (sip:192.168.1.15) transmitting to port 0 (USB PnP Sound Device: USB Audio (hw:0,0) (44KHz)) 11:06:45.431 pjsua_aud.c .....Conf connect: 0 --> 4 11:06:45.432 conference.c ......Port 0 (USB PnP Sound Device: USB Audio (hw:0,0) (44KHz)) transmitting to port 4 (sip:192.168.1.15) ===== The boxes are connected but no sound can be heard at either end.
