PS3 HDMI video, RCA sound

Can anyone tell me how the heck you get the sound to come through on the analog channels on a PS3? I’ve gone into the audio settings and turned on multi-output, but I still get no sound. I’ve read the manual back and forth and upside down and near as I can tell that’s the only thing I should need to do.

Edit: just as I post, I figure, what the hell, I’ll try a different cable (the L/R lines from the PS3 run into an adapter cable that has a 3.5mm jack on the other end to plug into the line-in on my computer sound card). It works now. First time I’ve ever actually had a bad cable.

Its the menu option below where you configure the video output.

You will get the chance to output to HDMI, optical, or RCA.
