Description

I have a 5.1 USB audio system (I reckon the issue is the same on any 5.1 system).
See the attached /etc/asound.conf
When playing 5.1 content (usually mkv/ac3), the video hangs at start.

For info, vlc 1.0.3 code path works.

I do get:
alsa-init: got buffersize=216000
alsa-init: got period size 6000

But in libao alsa play, I get to play all the time less bytes(~=65000) than ao_data.outburst(~=72000) which make 0 bytes to write to the alsa device.
