winealsa/dsound: Testers asked for capture patch

[ling weak]

Sorry, I couldn't notice any improvements using that patch.

For your information:
> From wine-0.9.36 to .39 graphics and sound were very choppy. As of

wine-0.9.40 video is still stuck at 4fps but audio plays stutter-free. I
think this was caused by your remixing-patch.
