I had been using the red/white cables from the RCA cables to get sound from PS3 to the sound projector. The details in the treble were crystal clear and the bass was powerful with the Sony subwoofer I use with it. But recently I discovered only stereo was possible with the way ps3 was designed to output, unlike most players or systems. So naturally I picked up a new optical cable which then allowed me to select surround sound options instead of only 2 channels for stereo. Stereo mode sounds identical, and when my sound bar goes into DTS surround mode, it sounds amazing. But when i play games or certain films that use Dolby, the sound is muddy. An exaggeration would be to say it sounds more like it's playing underwater. Not that bad, of course, butcomparable in terms of the decrease in audio quality. I've tweaked the settings till I can't stand listening to it any more. Any suggestions or advice? I'm not sure why this supposedly superior alternative sounds worse in certain modes yet perfectly fine in others like it used to.
