requesting review and/or testing for directsound changes

I did some testing with the shiny new sound code. I tested with and without 
pulseaudio, with current dsound, native(win7) dsound and your precompiled 

Pulseaudio + current code: Sound effects are sometimes garbled or partially 
played, but are on time and not repeated

No Pulseaudio + current code: not tested

Pulseaudio + maarten's binary: Old sound effects played over and over again, 
after a few seconds the summed up effects morph into static

No Pulseaudio + maarten's binary: Crashed once, on a 2nd try it also loops 
effects all over, sums up to static after a few seconds

Pulseaudio + native dsound: Effects play OK, but sometimes the sound is 
interruped and afterwards delayed. Delays sum up

No pulseaudio + native: works perfectly.

BF1942 had a mouse regression recently. I tried to disable xinput(by 
commenting out the HAVE_XINPUT*_H defines in config.h) and recompiling but this 
did not help. I also tried native dinput(with and without xinput), but this 
did not change anything. The symptom is that the mouse is mostly moving at the 
edges of the screen and can be moved away from there only very carefully. This 
worked two weeks ago. I'll try to run a regression test.
