Polling is the way with DirectSound.
I have currently no problem with playing and capturing 20 ms frames on my SB
Keep the number of needed threads in your application as small as possible.
Previous I got stuck in a scenario where I had simply too many threads doing
simply too much to be able to
get everything done in time.
