Before any flames appear, here is what the Envy24HT chip does:
1) 8 channels joined together + independent stereo S/PDIF out
2) 6 channels joined together + stereo + S/PDIF
3) 4 channels joined together + 2 x stereo + S/PDIF
4) 4 x stereo + S/PDIF
Unfortunately, the hardware cannot sum (mix) the stereo signals, so if you
want to mix multiple stereo streams, you will have to buy another hardware
or use dmix (after 32-bit mixing is debugged). It seems that this chip is
designed primary for DVD 5.1 and 7.1 streams + forwarding digital stream
using S/PDIF out.
Anyway, I received Revolution so I will test the S/PDIF output soon.

BTW: The matrix entry for Revolution was fixes.
