Hello, I noticed a problem with the pjmedia alsa audio device error handling. I've fixed it in the atttached patch against version 2.0. - Earlier an error (stream was suspended, interrupt, unknown) would lead to a busy wait, maxing out a core. - EPIPE, ESTRPIPE, EINTR and EAGAIN are now handled by snd_pcm_recover. Other errors are ignored and we sleep for 100ms before snd_pcm_prepar-ing the device and trying again. This is probably not the best way - we need an error callback to handle things like devices being unplugged etc, but this seems to recover from alsa 'Unknown error' returned by alsa in snd_pcm_readi/writei when using pulseaudio as the back end Thanks -------------- next part -------------- A non-text attachment was scrubbed...
