Hey I posted this on the official Playstation forums and nobody's options worked for me so maybe you guys can help. It seems ever since I downloaded the 1.80 update (I'm now updated to 1.81) I haven't been able to get sound out of my launch games like Resistance or NHL 2K7, unless I just set it to plain 2 channel HDMI. I have my sound settings set to accept HDMI with DTS 5.1 selected as well as the defaults. I also have my Home Thearter set to accept Pro Logic II sound. All of my other games have sound, like Oblivion, Motorstorm, VF5, it's just my two launch games that don't. Maybe I have my settings incorrect? Here's a link to my Home Thearter, maybe I have the wrong settings for what this thing can really output.
