I am having a problem where the DD 5.1 and DTS audio tracks aren't being passed to my receiver on my PS3. I have the PS3 hooked to my TV with HDMI and then a optical cable goes to my receiver for sound. The same setup as my Directv receiver and my 360 and they work fine. I went through the audio setup on the PS3 and set it to allow DTS, DD was already there, and still not the correct sound. I do get sound through my speakers just not DD 5.1 or DTS.
