Short, very annoying buzz!!!

Have a HR54/500 with a C41W-500

Every time I change channels, pause then play and also when a channel goes to commercial and comes back from commercial, there's this very annoying, short buzz noise. It's about a second long spurt. I've reset everything several times and it doesn't go away. It's so bad one of my pups ok leaves the room whenever it happens. Just can't figure it out. Any ideas?

Is the C41 connected to an Audio receiver or directly to the TV? 

This is likely happening whenever the dolby digital bit stream is interrupted, or goes from DD to PCM, and the audio system in the Audio receiver/TV can't handle the interruption. Disable Dolby in the Directv system and see if the problem goes away.

Your TV probably can't handle DD anyway..

You nailed it!!! Buzz gone, happy dog and master. C41 is connected directly to TV. TV is a TCL 55S405. TV menu for spdif and ARC has selection for:

-Auto Detect

-Auto Passthrough

-PCM

-DOLBY DIGITAL

-DOLBY DIGITAL Plus

-DOLBY DIGITAL, DTS

-DOLBY DIGITAL PLUS, DTS

I guess it can handle DOLBY but not from Directv C41? What's strange is I've had this TV for 3 years now and this buzz started slow. At 1st it only happened when paused and play. Buzz noise when commercials ended just started a month ago. It just got worse over time. All good now except the audio is much less vibrant. Time to get a sound bar. Thanks so much!!
