Mac mini refusing to play audio now?

[Doju]

Hi, I was using my Mac mini last night and it played audio fine. (I have it hooked up to my HDTV in the living room.)

However, this morning I went to watch a standup comedian and the audio wouldn't play. I rebooted. Removed the audio cord and plugged it back in. Took the video cord and plugged it back in.

Audio cord: composite
Video: mini-DVI -> DVI -> HDMI

Nothing will play. There's no external speakers or anything, it's playing through the TV's built in speakers.

Normal satellite TV will play audio as well.

Can anyone help?

THis might be obvious, but make sure your sound output on the mini is not set to MUTE. Also, make sure the output is set to the correct device. Both can be found in the System Preferences.
