I haven't been around in years since my 990 has been working perfectly. But a couple of weeks ago I hit a snag that I can't find mentioned in the forum--search didn't find this one has been mentioned. I tried to watch the Sarah Conner Chronicles on Fox-TV local outlet OTA channel 27.1 in Champaign, IL. I got no audio--every other channel works fine with the same settings. The OTA channel 27 comes in fine with audio--it's just the digital that has no audio. I have fiddled with all the buttons and can't figure this one out.

I have a Sony SAT-200 acting as the OTA tuner and am feeding a dig. optical input into the 990.

Any ideas?
