My speakers were just fine yesterday.
This morning, however, I woke up the computer and turned on my Altec Lansing 5.1 speaker array and… HSSSSSSSSSSSSSSSSS!
I unplugged the jacks from the computer, no change. I fiddled with the knobs, turned the speakers off and on, no change. I unplugged the power cord and plugged that back in again and… change.
Now they don’t turn on at all. I guess I’m going shopping later. Le sigh.
