I'm almost there to buy a card with an emu10k1-chip... if I were sure it would "solve" my problem :) > If PCM stereo mode does not work, then your sound card does not support > SPDIF output in a way we can deal with, and AC3 and DTS will never work > with your card. dts works - so I guess this is not the case?
