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?
