No Sound Freakout

My story may save some of you from unwarranted panic, sweat and one hell of a lot of cussing.

We experienced 3 electrical power glitches spaced about 5 minutes apart. Super surge protecter didn't do its job. Comp. froze and had to be restarted a couple times. I won't go into all the details but the desktop was a mess and NO SOUND except via headphones. Took 2 hours to restore last night's backup. I BACKUP faithfully.

Backup restored (thank you Acronis) and all systems go except still NO SOUND. When testing the sound system, devise manager showed nada wrong.

Soooo we unplugged the external speakers and plugged them into our laptop. At that point I noticed that the gizmo that is connected to the speakers that sits on my desk and allows me to minipulate the sound level and the woofer was not showing its blue light to indicate it was on. The power glitch turned off that gizmo and that was why there was no sound.

OK OK you have a right to laugh .

If you have that gizmo, keep in mind that a power glitch may turn it off -- thus no sound. Check that danged thing before you do anything else.

Hope you all have a great holiday.

Sounds like the fuse is blown in the amplifier for the speakers, if you can be bothered opening the unit that you manipulate the sound with, try and replace it, if that doesnt work its the PSU. I know a fair bit about electronics and with power surges these are the 2 most common solutions for this type of thing.
Fuses are only interchangable if you know the amplitude and the size, also most of the cheaper speakers wont have them, hence the PSU change. Just like a computer speakers have a psu (unless they are ridiculously bad) if you know what you are doing replace this and perhaps check the capacitors. - this is very different to a computer, so be careful with what you are doing.
If you dont want to go through the trouble, just buy a new pair and get a belkin, they have an $80 000 equipment warranty for their surge protectors here in Australia.
