[rfc] dsound: decrease sound latency

[Maarten Lankhorst]

Hi all,

Please test this and let me know if it's causing any problems in sound 
playback, preferably with media applications and games, any feedback 
would be appreciated. The patch won't fix existing problems, it should 
just decrease the audio lag. As such I would prefer only to receive 
feedback on issues INTRODUCED or FIXED by this patch.

If it's causing issues, I want to know:
1. Whether pulseaudio is running, and pulseaudio --version
2. What distribution you're using
3. (If you know it) the version of alsa's libraries, packages libasound2 
and libasound2-plugins in debian/ubuntu

Cheers,
Maarten
