Sound in MGR with in-home streaming

So I recently wired my home with cat6 and set up a gigabit switch and all that, so I decided to try out some games with Steam in-home streaming. Most games I tried worked well enough that if I didn't know any better I would have thought it was being played locally, MGR included. However, for some reason this game in particular is giving me weird sound issues. I get sound in cutscenes, but no sound "in-game" for lack of a better term. When just playing it on my main machine I have no sound issues, and I can't seem to nail down why just this game is having issues streaming sound when the others I tried worked. If anyone knows anything about this, any help is appreciated.

Have you asked in the Home Streaming discussions board on Steam? You will probably get a much better answer there than on the GB forums.

@chiablo: I did a bit of reading on there before but could not find what I was looking for. Might as well give it a shot anyway. Thanks.
