After software update this morning at 0300, one of my TV's lost audio. Can't get it back.

Double check audio settings to make sure they haven't mistakenly changed things.  For example, defaulting back to Dolby Digital when your TV doesn't support it.

You may have gotten a incomplete update.  Depending on the STB model you may be able to force it to reload again.
