I wanted to play a short sound and release the pcm. It works with a non-block drain as Clemens suggested.
I noticed using gettimeofday() around drain() that it takes a bit over 2 seconds. Rather long for a sound that only takes 0.1 sec.
That is a known pulseaudio problem; which we also noted on PulseConf a few weeks ago. I want to do something about it but it is not on the top of my priority list right now.
Are the rest of you trying with PulseAudio as well? Maybe it could be worth also trying the direct plughw path do see if the behaviour is different.
