I have had issues others have discussed here with lost audio and lights going out on front of box intermitanly since last upgrade. Today, I have audio problems. The voices are very quiet on some channes (doesnt matter whether the broadcast is pro logic or not). This happens on MOST channnels some are fine. I am connected via optical TOSLink. I dont think its my audio reciever because A: DVD's play just fine (but thats a different input) B: My recorded shows on the 622 audio is all fine. Its just the current feeds. Anyone else?
