Need help getting audio to output to TV.

This shouldn't be hard. I don't know why it's not working. I'm using a late '08 Unibody MBP 15" and a 52" Sony Bravia LCD TV.

I have a Monoprice MiniDisplayPort-to-HDMI cable, and it works great (I'm aware that there's no audio passing through the HDMI, even though technically it should be able to pass it through). Picture looks wonderful.

However, the audio will not work. I'm using a 1/8" (headphone) to RCA (left/right) cable, and I cannot get it to work for the life of me. The cable is good. It works for other applications (iPod to soundboard, etc). I plug the MDP-to-HDMI cable into the HDMI 2 port and the computer...bam...works great. Then I plug the RCA-to-1/8" cable into the computer's headphone jack and the appropriate inputs for sound underneath the HDMI 2 port, and nothing. Is there something I'm supposed to do to enable it? All volumes are correct on the computer and the TV. I'm tried other HDMI inputs and respective sound inputs, and still nothing. I've checked the System Preferences for sound, and the "output" is indeed the headphone jack.

ANY HELP AT ALL would be appreciated!! Thanks!

this is most likely an issue with your tv. I have my mini setup the exact same way. You might need to go into your tv's menu and enable that analog input. The tv might think the sound is coming through HDMI instead of RCA.

Also, without letting us know what TV you have, it's kind of hard to help you.

I did let you know. It's at the top of the post.

EDIT: I tried adjusting settings to no avail. I can't find anywhere in the menus to "enable" the audio input ports. I'm assuming they just work. Each HDMI input has stereo RCA audio jacks right underneath it. That's where I have it plugged in. All volumes are up where they should be. :/

Any other ideas?

There are several different 52" bravia LCD models, from different years, do you have a specific model number?

I lost it. Everything needs to be completely intuitive all of the time.

But yes, that did work! Thanks for your help!
