TV tuner card no sound, help!

[zzzmick]

Hi, I know pretty much nothing about apples.
My boss has an older one with a TV tuner card und uses it to watch TV in his office, nothing else.
For a few weeks now, he has TV picture but no sound.
If I put a music cd in, the sound works, all other sounds work as well. (using built in speakers). I checked the mute and volume control in the program that he uses to watch tv, all settings are OK. The other TV, thats on the same antenna has sound.
So...my logic tells me it has to be a bad tuner card, what else!?
Any advise would be greatly appreciated. Thanks!, Mike

Try going into the sound control panel and selecting 'sound input' or 'sound in' (depending on what version you have) and choose TV/Video system as the input.

If your Mac's battery is dead you might need to do this at every startup, or make an AppleScript to do it for you.

I had this with my G3 B&W. Had bought a TV tuner card, but no sound, and connected it correctly to the sound ports on the motherboard according to the manual that came with it. Never got it to work properly...
