For audio I have 2 output choices, one is the regular green line in cable.. and the other one is spdif through optical. Normally I can switch between the 2 playback choices just fine in win7's volume mixer. Right now I have it selected on the regular output (non optical) and everything plays just fine (WMP, firefox, VLC etc) but I have 1 program that is playing under optical and I can't figure out how to change it back so that it plays with the rest of the programs. I checked under playback devices and the one I want is already selected as the default.
