We very much appreciate that this community is taking a good look at
Vista and giving specific feedback like this. Thank you.

Please give us a couple weeks to study this issue here to see if we can
offer some alternatives for certain classes of applications like this.
If you hear nothing more within that timeframe, please raise the issue
again.

I agree with Jeff and Dan -It looks like this is going to be a huge
problem for professional applications that still use the mixer API and
expect full control over the h/w.  Is there a way that the audio
subsystem can be put in a "legacy" mode to make it act like 2000/XP?
