I'd only enable the ones you're sure you're going to use and that your system supports. If you chose to enable them all, one setting might take priority over another and function improperly. Does it not auto detect the settings properly?

I'm having the exact same problem. I get audio at normal speed if I use the HDMI throught the tv speakers. How about you? I'm ready to bring it back to Best Buy.

Not sure you can correct this. If it's not some option that needs to be selected or decelected by the user, it's probably going to have to be fixed by a professional.
The fact it works at 1.5 speed and in the menu tells me the problem is with the PS3. The fact that it works with HDMI at normal speed tells me it's reading the disk ok, so somewhere between the disk and optical out there is a problem. I just don't know if it's software or hardware.

I'm having the same problem and I know for sure it's a problem with the PS3 update. I have been using the my digital optical cable with my ps3 to the surround sound for about a year and have played all kinds of games (including fifa soccer) with digital sound. Then after doing the recent update all of a sudden no sound with fifa soccer. I bought a new game (Assasin's creed) and no sound with that either. There is however sound before I enter the game and I have no trouble with streaming videos. This is definitely a software and not hardware issue...yet again sony's system update messed up something that was working just fine...anyone know anything else about this problem?

I have the same sound problem. With my sound problem I have to reset the console or game until finally I have sound. I just recently bought my PS3 and had to update it too. Once the sound works then it finally stays on without problm. I just have to restart it which is very annoying. Can anyone help me find out why. I will stop buying into PS3 if the first console I bought was a defect. Very unhappy so far. I should have stayed with XBOX 360.
