It looks perfectly legal to me.

It depends on what is acceptable to you and/or your customers.  It 
looks like a fix needs to go into the NVIDIA backend (assuming that's 
what is being used here -- I think that's the case), and it needs to be 
rolled into their driver release.  If you need things to work in the 
meantime or a driver update isn't acceptable to your customers, then 
you'll need to do some work on the initialization -- find the name of 
the device you open, and if it's NVIDIA then close it and open up the 
DirectSound device instead.  Enumeration can help you out in this 
situation perhaps -- in that you could pick a sensible default for your 
customer, but allow them to override if they know better...
