Actually I have suggested a plug+dmix configuration (look at my
previous message), otherwise your app needs to match the sample/bit
rate of dmix which default should be 48kHz ??bits.
You can configure dmix to a particular bit.sample rate that works best

I haven't experienced any audible problems with plug/dmix resampling
but your ears could be more sensitive. I would be surprised though if
upsampling to 48kHz (which is the default dmix mode) is really that
