Anything that is different than that frame rate has to be resampled to match or it can't be played. So as long as you are playing audio encoded at a hardware rate your card supports, and the sound server opens the device at that rate, it is transparent. Except for the format conversion that Bill showed has a negligible influence on sound quality. I think the blood rushing through our ears makes a sound louder than -96 db. :-) > Other than what's been mentioned, ALSA will do a perfect job of > passing the audio straight through to the DAC? > Yes.
