hey Chad try this first if you have not already done so. PS3 loses sound when using optical lead. No sound on bluray movies. Sound to tv or surround sound is not working.
1. Turn ps3 off at back of unit
2. turn back on ( red light comes on)
3 press and hold finger on on off switch ( front)
4 wait for two beeps and a further double beep
5 on screen 6 options
6 choose option 2
7 add your details then when complete sound should be ok
