If xp, try going to: Control Panel, Sounds. Then click “Advanced”. Make sure none of the bars are all the way down.

Perhaps the driver mysteriously corrupted itself. Shit like that happens for no reason sometimes.

If you’re on XP… right-click “My Computer” and click properties, when in the set of tabs in the window that comes up, click the “hardware” tab, then click the “device manager” button. Make sure nothing in the device manager has an exclamation point next to it. It usually automatically opens up any device category that has an exclamation point next to something, but if not, you might have to click the + next to “sound, video and game controllers.” If there’s no exclamation point next to anything under “sound, video and game controllers,” make sure your sound card is actually listed there (mine says “Creative SB Live! series” but yours might say something else). You should have something listed besides “legacy audio drivers.” If you have a sound card listed and there’s no exclamation point next to it, then as far as Windows knows everything’s fine.

But slightly OT, has anyone else with Firefox 3.5 noticed that loading LSB seems to cause the “script on the page has been stopped due to a low memory condition” warnings that have been plaguing 3.5 users?

I know the new FF 3.5 bug is a fairly common problem, but I’m just noting that viewing LSB in FF 3.5 is becoming nigh impossible.
