I just picked up a used monitor a few days ago, that has a volume knob and mute button on the front of it, and I can't seem to figure out how to make them acctually do anything.
There is only one jack on the whole thing (mic out), and I tried to download the drivers from the manufacturer (compaq), but the installation file dumps me back to a prompt just before it starts extracting things (downloaded it again, same thing).
If it only has one jack for mic out, then I'd guess that vol and mute button is for a built-in microphone. If that's the case, you might be better off just using a mike through external speakers or hooked up directly to the sound card. Probably get better performance than through a mike on the monitor.
