Advertisements New to the forum. I have a Tivo HDTV 250 unit and it has been having intermittent audio problems. Seems like it is on the local channels that DTV transmits. The audio is on for a few minutes and then goes out completely for a few seconds then comes back on. Does not seem to have a pattern that I can tell so far. We've had the unit for ~ 6 months without any problems. Is the unit going out or ??? Thanks for any help.
