Hey Paul, Sorry for the very slow reply (I was on vacation last week). What worked for me was to disable port audio and always use alsa (thanks to the advice from others on this list). I did this by editing this file in the source code: pjlib/include/pj/config_site.h and adding the following #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1 #define PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO 0 Hope that works for you. The issue I'm running into now is the sound quality is not great. If you have any success on this front, I'd love some pointers. -Matt Date: Wed, 11 Sep 2013 11:47:20 +0200 (CEST) > From: "Paul Schmidt" <8flm6@xxxxxx> > To: "pjsip list" <pjsip at lists.pjsip.org> > Subject: Re: Can't find audio device on Raspberry Pi > Message-ID: > > <trinity-cae81fbd-0194-4d13-98db-4ffe517227e0-1378892840468 at 3capp-gmx-bs56 > > > > Content-Type: text/plain; charset=UTF-8 > > > Hello Matt, > > so far you're the only one who replied to my question.
