Apparently if your device driver advertises itself as having a "hardware mixer" and promises to be compliant to AC97, Windows will let it do the mixing instead of using kmixer.For example, my Audiotrack Prodigy 7.1 will play back DTS files fine, because it *has* a hardware mixer. I think this is also the case for some of the other soundcards based on the Via Envy chipset.
The reason why this discussion is interesting is because the Benchmark USB DAC claims to use generic XP USB drivers, which (I think) do not register as having a hardware mixer to the OS.
PS - a clever idea would be to claim to have a hardware mixer even if you don't, and implement software mixing in the device driver.
