where i am at we had a power outage and both my desktop and laptop were on well i was just shutting down my desktop when we got the power back my laptop and desktop powered up and it seemed nothing was wrong, but can power outages create audio problems on computers like make audio uneven like for example audio working on both sides but the the right side louder than the left or vice versa?

There are innumerable things that can happen to any one of those chips during a power outage.  Abrupt removal of power can create over-voltage spikes.  Most often it's not the dropping of power that causes faults, but the initial cause that created the drop.  Power surges from many causes will do the most damage, overheating in short periods (less than a second) or breakdowns in insulation.  Natural causes can be lightning and higher voltage lines tangling with lower voltage gear.   These events can enter the home through any wire/cable originating outside the home.  Protection is important and surge protectors and UPS units can add extra layers above those included within the current gear.

Are you currently experiencing this left/right audio problem?

 

For Windows 7 you can change volumes on the left and right channels.

Audio equipment responds a bit differently to electrical surges than most other devices.

We have been haveing a number of power outages with sudden restoration of power because of ongoing line work in our neighborhood.

I have 1 tv that has a 2 " white border around the screen and 2 surge protected powerstrips that no longer have surge protection.

Ohh and very important 3 dead coffee pots. lol  None of which will likely be replaced.

DB950 sounds like a severe case.  I have had a traffic accident nearby that knocked over a power pole.  It also dropped 12 KV lines unto a 3 KV line.  I lost one transformer, a UPS (small one, 1 KVA and a ground arrestor.  This could have been worse without the protection.  When intermittent problems on a line causes variations in input voltages, internal parts (power supplies, circuit boards, anything that has AC voltage applied to it, has to have its own built in protection or it doesn't get the Underwriters Labs seal.  This however a one shot deal, once an has occurred and the circuit provide the needed protection, it is toast.  It is sacrificial.  If the device continues to work, that's good, but now it has no more protection.  These surges can also cause any device to be  "struck" and a gate may get stuck in one state.  This could cause any fault.
