Hi All,
Funny thing happened the other day: my sound turned off, and I couldn't get it to turn back on. I hadn't been doing anything unusual, I'd just quit QuickTime Player.
The volume controller in the menu bar was colourless (like it was inactive). I could move the volume slider around, but it had no effect.
I went into the sound control panel, fiddling there had no effect.
I logged out and back in, no change.
I logged in as a different user, no change.
I rebooted, no change
I rebooted and zapped the pram, no change.
The fix? Get this:
I plugged some headphones into the front headphone jack, and my sound came back! (even when I unplugged them).
Weird.
Chas
