Question about Sony STR-DE685 Receiver
A few days ago my surround system began sounding muffled. I haven't made any changes to anything. The muffling on some TV channels are worse than others. I called Comcast and they even swapped my box and still have problem. I also noticed that my blu-ray is also muffled which indicates to me it's the receiver. I checked all cables and nothing is frayed or shorting. I also rest the fctory settings just to be sure and still no solution. I guess my receiver has finally called it quits, but I wanted to send this out for an opinion.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

SOURCE: my tv speakers are muffled
The speakers sound all good because you said "the speakers" are muffled .....it sounds like a problem on the board.....a capacitor a resister but its fixable....unfortunately only by a repairman

Your amplifier should "downgrade" the signal to 5.1, even if the disc isn't using it. It is most likely a setting on your amp that may need adjusting for "types" of digital to accept on its input. If you can, set your optical input on your amp to "auto". This way it will automatically detect and switch for the proper incoming audio feed

I think it might be a driver or a codec missing. Eeeh... do you hear the same thing while listening to music? If you don't it is definitely a software issue! From here I would try reinstalling the software, or get the most updated version of the software (I'm assuming you're using Windows Media Player). Let me know if you're using a specific software.

I had this problem last night.
To solve it, you can reset the amp by:
1) Put the receiver on stand-by
2) Hold down "MODE" button and press on button
3) "S.F. CLR" appears in the display and surround is back on.
