Hi all, For wine I was investigating a bug with pulseaudio, it seems alsa-plugins' pulse driver ignores underruns. This is probably because an underrun will force you to call snd_pcm_prepare, this will destroy the stream and set up a similar new one again. This causes more susceptibility to underruns, so that code was disabled. However if I force underruns to occur, the state will stay running and it appears there is still some data left in the buffer, so sound stalls entirely. The latency gets updated to something like 0x7bdXXXXXXXXXXXXX which looks suspiciously much like a pointer to me, which may be a bug. If I instead make pulse_prepare call pulse_start on underrun, it's handled properly and sound will continue to work. So my questions are. 1. Is the weird latency value update a bug? Digging it up I can only assume it's a bug in src/stream.c , but I haven't figured out why yet. Tested with pulseaudio.c 2. Any comments on this patch for alsa-plugins?
