Small DSound fix...

[Robert Reif]

This patch is all wrong.  It makes no sense to pass a
software class id to a function that only accepts hardware ids.
The real bug is in the class factory. 0 should be passed rather
than the class id.  Look at the capture part a few lines below it.
Passing 0 or NULL will select the default device.

I can't generate a patch now but the trivial fix is to pass 0 rather
than the class id in the class factory.
