problems with audio for games

[buckshot]

I know this has been asked before, but the suggestions given in the threads i've found haven't worked.

I have a ps3 and started using the hdmi for audio and video. I have the hdmi going into my tv and optical going from my tv for my receiver. the audio for movies is great, and I can hear the audio when I am on the icons for demo games. but when I play dames (demo or full) the audio disappears. I waited until after update 1.6 to seek help about this. when I use the optical as my audio out for the ps3 you can hear just fine. so what the f#%$ can I do? i've tried pulling out and replacing the hdmi, reseting the ps3, unplugging the ps3, using a different hdmi cable etc etc. so what can I do to get my audio back?

I would use my optical cable as the audio out but the cable isn't long enough to reach my receiver.
