I can't seem to isolate this behaviour - it seems to vary from instance to instance of pulseaudio, although when it starts it continues to get worse until no sound from the system is recognisable at all. The error logged below is easily reproducible by playing multiple audio/video files at once, although it often occurs whilst playing only a single file. Changing settings (5.1 surround, stereo, stereo duplex, etc) has no effect on the behaviour. Also, the pulseaudio log identifies my audio controller as "HDA Intel", but I know for a fact that it's a "Realtek ALC892". I have not had the chance to attempt to reproduce this on Narwhal or earlier versions, but I will soon. ========================================= Pulseaudio error logs: E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. E: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
