I have a question about the hdmi and the sound, I have the hdmi hooked up on ps3 to tv and I use aux cables to hook up my home theather system. My audio system is 5.1 surround sound but when I go on the audio settings to detect it only detects the tvs 2 speaker sysytem, is there any way I can get it to signal the 5.1 like this or am I gonna have to get a reciever to plug in the ps3 to surround sound?

May be because you are using aux cables (just a white one and a red one?); you can't carry 5.1 sound over those.  To get true 5.1 you have to use either HDMI or optical out with the PS3.  Hope that helps.

There is an audio selection in the settings.  I think it should auto-detect possible outputs, but you can manually choose to output 5.1.  If you have an output selected that can't be used, then you'll get an error message when starting a game.  That's what happened to me anyways.  Make sure you have your stereo system set to match as well.  Mine is kind of funky, so I had to manually set each input/output.  I hope that helps.

EDIT: Also make sure you change the settings so that it does not try to put sound through the HDMI.  I think it defaults to that.

Also make sure it's outputting the bitstream, because PCM over 2.0 can only be output through HDMI.
