Sound problems!!!

I have been having audio problems between my Xfinity X1 DVR box and my TV. The TV is a Sony Bravia KDL-55EX640 with 4 HDMI inputs. The DVR is hooked up to HDMI input 1 using an HDMI cable that I already owned. It wasn't a cheap one and might be slightly longer than the standard cables given out with the DVRs. Also connected to the TV is a Roku on HDMI 2 and a BluRay player on HDMI 3. The Roku is normally powered. The BluRay is normally off. 

Sometime last fall I started having audio problems. Basically, it worked at night, but then did not work the following morning.  I first discovered that pulling the plug on the DVR fixed the problem. Then I discovered that resetting it through the Xfinity Account app fixed the problem. Then I figured out that if you just tell the remote "Help", it opens the screen with the reset command, and that fixed the problem. It does work if, once it is working, you turn it off and right back on. It does not usually work if it remains off for more than a couple of hours.

Because of the pandemic and weather and perhaps a bit of laziness, I did not try to replace the box until this week. So I go and get a new box, swap it - all the shows are still there! Way to go Comcast! - and the next morning, there is no sound. So now I know it wasn't the box.

Since then I discovered (but haven't verified that it ALWAYS works) that if I just switch the input from the DVR to the Roku and back, it also fixes the problem without having to reset the DVR. And just now I figured out that simply pulling the HDMI cord from the TV and putting it right back in also solves the problem. 

Keeping in mind that this exact setup worked for years without a problem, my question is: Did my HDMI cable go bad? Is there a problem with the HDMI input on the TV? Is there some setting on the DVR that might cause this weird behavior AND stick with my account so that it caused the same problem on 2 boxes? The easiest thing to try is to switch the DVR to a different HDMI input on the TV and see if that solves the problem. I can also change the cable, but that is a lot more work. 

Has anyone else had a problem like this??

Update: Switching the input did not solve the problem.

Update: Switching the HDMI cord didn't work either.  I suppose I could try switching the cord and the input, but that seems silly. For what it is worth, the Roku is always on and it never has a problem. 

Now I am really at a loss. Is there something wrong with the TV?

not likely the TV at this point since you don't report other inputs having the same problem. do you have another set top box to swap to see if the problem follows the set top box? do you use your TV speakers for sound or have audio from TV routed to a receiver/sound bar?

I have already swapped the old box for a brand new one, and the problem remained, so I don't see how it is the box unless it is a software configuration problem (nor do I have any other boxes).  I am just using the TV speakers. This is in a bedroom, and I've never felt any justification for a sound bar. 

By the way, I also tried unplugging the Roku and leaving it unplugged, but that didn't help. I haven't tried unplugging the BluRay player (which is rarely used). That would be easy enough to try, but I don't see how it could be the source of the problem.

since you have the roku, have you tried running the Xfinity Stream beta app to see if the sound works that way? it is not as good as a set top box by any means but I just mean for testing the sound. Also, when you insert each end of the HDMI cable are you hearing and feeling the fully inserted 'click' as it locks in fully seated?

This is definitely an issue. I actually searched for a thread like this in hope that there was a resolution for this problem. I’ve been having the problem where the sound goes really low even with the volume on Max. I do use a sound bar and at first I thought that was the problem but it definitely isn’t the issue. I’ve been having to pause what I’m watching and then I pause it for the volume to fix BUT after a few mins it happens again. I’m honestly so sick and tired of going thru this. I shouldn’t have to keep pausing my tv and unpausing and every few mins, ESPECIALLY when I’m tryin to watch a movie or something. I am glad I’m not the only person going through this because I kept thinking I was the only one so it had to be something wrong with just my equipment. Xfinity needs to fix this problem before they lose customers. I surely don’t want to continue having to deal with this.

I too have the same issue! In my case, many times the characters voice will not match their lips OR all sound will be distorted !

" When this happens, Just use the the remote to pause then play again" While this may work, it is only a temporary fix!

Have had the lagging speech for months I just went to audio menu and switched from Dolby 5.1 to stereo and no more lagging.
