Hi All, Whenever I make or receive a call with pjsua, I receive the following warning messages.. warning: discarded first playback frame warning: Had to discard a playback frame (your application is buggy and/or got xruns) warning: Auto-filling the buffer (your application is buggy and/or got xruns) Which quickly repeat over and over, which makes it difficult to see log lines about whois calling, etc. I'm using G.711 PCMA/ALAW Codec for the calls. The calls work and sound ok. >From doing some googling, it could be something to do with echo cancellation? I am running void linux on a macbook - Can anyone tell me where to start with troubleshooting this please? Regards, Ilias. _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip@xxxxxxxxxxxxxxx http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
