yes, the ac3 bitstream parsing is 100% sure done by driver, but i can imagine
that they utilize the card's DSP to do the IMDCT transformation and
downmixing. anyway it isn't possible under linux unless someone develop such
code (or RE. the win driver) for the emu10k1 DSP (there is opensource
assembler for that chip...)
