Ugh, I switched from Vista to 7 and now my built-in monitor speakers aren't working. I've tried drivers for the sound. I've tried reinstalling the monitor drivers. I have checked and rechecked that I'm plugged into the right jack, cables are connected, etc. They were working in Vista (still work if I boot into it), just not in 7.
I think the problem is the speakers just aren't even listed in playback devices. The HP support site is no help (leading me in circles).
Please help, I'm going a little batty.
