Hi everyone, I'm running into some trouble with buffer attributes in gstreamer pulsesink and pulseaudio. It seems that if prebuf is non-zero, then I can get much better cpu usage from pulseaudio and gstreamer. One problem I am seeing is on EOS when the file being played is finished. I always seem to get a buffer underrun callback from pulseaudio at the end of the stream. The problem is that when prebuf is non-zero, when the underrun occurs, timer updates from pulseaudio no longer update the time. This is probably due to underruns causing a wait until prebuf amount is filled.
So my question is, pa_stream_trigger() should start the stream playback immediately without waiting for prebuf to be filled, but I am not seeing any timer updates occurring after i call trigger. I also call drain when the EOS event occurs, but this doesn't seem to update timer either. Also, why is it that I always get a underrun message when the file is done playing? Happens with gstreamer, aplay, paplay. Thanks Baek
