Question about Panasonic Viera TH-42PZ80U Plasma TV
It is an issue of automatic gain control software for the audio signal. The issue happens if you have a short outage of your cable signal. The TV tries to amplify the audio signal that isn't even there. When the signal returns, the TV software is not programmed correctly to drop the amplification (not automatic gain decrease -just increase). The only solution is a factory reset of the TV.

If you get your tv through some kind of set-top-box (if you have cable or satellite tv for instance) the STB (set-top-box) may have it's own volume control that is set to a low level. You will have to look through "settings" on your STB.
