Hi Alexei, Currently, Mac's CoreAudio backend will use the first audio input/output device. I just committed the change for it to use the system's default audio input/output device instead in ticket #1196 (http://trac.pjsip.org/repos/ticket/1196). Please let us know if there is any problem. Thanks. Regards, Ming On Thu, Jan 13, 2011 at 7:33 AM, Alexei Kuznetsov <eofster at gmail.com> wrote: > Hi, > > I'm on a Mac using pjsua 1.8.10. I have a bluetooth headset which is paired with the Mac, but is not being used. When I make a call pjsua tries to open an audio device. Nothing happens and pjsua retries to open the device again and again. Then standard dialog box from the OS appears that says that bluetooth audio failed and there is a button "Stop using headset". After pressing the button pjsua prints out the last two lines, and returns to its default state with no active calls. During all this, default sound IO in the OS are Internal Speakers and Internal Microphone. > > Make call: sip:1 at localhost > ?02:17:10.833 ?pjsua_media.c ?Opening sound device PCM at 16000/1/20ms > ?02:17:12.912 coreaudio_dev. ?core audio stream stopped > ?02:17:12.913 ?pjsua_media.c ?Opening sound device PCM at 44100/1/20ms > ?02:17:14.923 coreaudio_dev. ?core audio stream stopped > ?02:17:14.923 ?pjsua_media.c ?Opening sound device PCM at 48000/1/20ms > ?02:17:16.936 coreaudio_dev. ?core audio stream stopped > ?02:17:16.936 ?pjsua_media.c ?Opening sound device PCM at 32000/1/20ms > ?02:17:18.949 coreaudio_dev. ?core audio stream stopped > ?02:17:18.949 ?pjsua_media.c ?Opening sound device PCM at 16000/1/20ms > ?02:17:20.978 coreaudio_dev. ?core audio stream stopped > ?02:17:20.978 ?pjsua_media.c ?Opening sound device PCM at 8000/1/20ms > ?02:17:20.980 ?ec0x10180f5c0 ?AEC created, clock_rate=8000, channel=1, samples per frame=160, tail length=200 ms, latency=49 ms > > ?02:17:41.588 coreaudio_dev. ?core audio stream stopped > ?02:17:41.588 ?pjsua_media.c ?Unable to open sound device: Unknown error 537310186 [status=537310186] > > > Why could pjsua try to open currently unused bluetooth audio device that is also not the default device? Any help is very appreciated. Many Telephone.app users suffer from this behavior. > > Alexei > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >
