[Bug 26965] Dragon Age 2 demo - sound in cutscenes is muffled

--- Comment #4 from Andrew Eikum  ---
The game always mixes to 5.1 surround. Wine's dsound doesn't support
down-mixing from 5.1 to stereo, so it just copies the first two channels,
front-left and right,  into stereo left and right. The game puts voices only
onto the center channel, so they gets lost during the down-mix.

dsound should support down-mixing 5.1 to stereo, and, dsound should also be
opening the backing device as 5.1 if it can. Either would fix this, and Wine
should do both.

The UseStereoSound workaround does seem to work for me.
