Sound only working on 4k channels

Is this a C61K receiver? How is the sound delivered? Has this been an issue in the past? Try a red button reset (right side). 

I’m having same exact issue.

HDMI 2.2

I am having the same issue. No sound on soundbar or tv audio. Restart did not help 

Having same issue. It's purely a directv issue. Not a cabling, not a tuner, not a soundbar issue. Confirmed as everything works except directv non 4k channels. 

Directv had an error in the audio coding somewhere. 

I have a Genie 2 setup with a C61K-700, and hdmi connected straight to the arc hdmi input on a Samsung 65” 8 series. I figured out if I unplug the tv for 30 seconds it will temporarily fix the issue, but once I watch a 4K channel for more then 20 minutes I then lose sound on non 4K channels, and have to once again unplug.

I found that if I watch a 4k channels, then after that, the sound does not work on the remainder of the channels.  I turn the TV and the Direct TV box off and on and not sure how. it eventually started to work.  now I just refrain from using 4K and no troubles.  But I like to watch 4k.

I unplug the power directly from the back of the TV. I do not have a smart power strip. TV is updated to current firmware.

I am having this same issue. Did we ever find a fix?

Unplugging the TV For about 15 seconds and plugging back in also worked for me. Shouldn't have to do that every time.

Had to shut off the box, wait a few mins, power on (repeat). Finally worked. This happens frequently after leaving a 4K channel. DirectV will never address it. So happy to be dumping them this February. Massive cost for just NFL ticket. 

Possible Solution

This has worked for me about a dozen times.

We all appear to be frustrated.

I saw a post about a similar issue. It was suggested that you hold down the "on" button on your remote for about ten seconds. This has worked for me about about a dozen times but it’s not 100%. This just started a couple of months ago. I’ve changed nothing on my TV set up. Sound works fine for all streaming services.

Just this second, I turned DIRECTV off (TV off too). I then pressed the "on" and the "off" buttons on my (DirecTV) remote at the same time for 10 seconds. I then pressed the on button and turned the TV on. Sound WORKED 

I have a Samsung TV 4k HD, a year old. I have a mini genie model C61K-700.

Possible Solution Part 2:

This morning I watched a soccer game on 4K for a couple of hours. Changed channels, no sound. I tried the same I tried yesterday day and it worked again, to wit:

 I turned DIRECTV off (TV off too). I then pressed the "on" and the "off" buttons on my (DirecTV) remote at the same time for 10 seconds. I then pressed the on button and turned the TV on. Sound WORKED 

I also noticed something peculiar on 4 separate occasions that this trick as worked - when I’m pushing BOTH buttons, and the TV and SAT box are both still off, after about 10 seconds I hear an audible click sound on the TV set itself. It’s like something has reset. It’s not a loud sound but it DOES happen. After that click, I turn the TV on and sound works on all channels. Obviously this is a short term solution. I have to hit the on and off buttons at almost the exact time to keep both the box and Tv off - otherwise, the TV wants to toggle on. 

I have a Samsung TV 4k HD, a year old. I have a mini genie model C61K-700. Sound is only from the TV speakers. All streaming channels work fine, sound wise. Started noticing the problem a few months ago. This solution was suggested by someone on the internet having the same problem.

This bandaid fix appears to work.

It took a while for me to troubleshoot this down to the DirecTV box (C61K-700, connected to Genie 2 HS17/100, wired), but I can confirm this problem only happens after watching 4K channels.  You have to watch for a minimum amount (> 2 minutes) of time, exact duration unknown still. Sound on 4K channels remains, but there is no output on regular channels. 

Thought it might be related to Optical vs. HDMI cable out of my Samsung 4K TV, but sound is fine for over the air channels (not DirecTV).

I can’t find any info on why turning off TV/DirecTV and pressing on/off simultaneously for 10 seconds fixes the problem. 

Part 3

I have noticed that the problem seems to occur when the 4K channel (104, 105 and 106 for me) has been on for an extended period of time - say at least 30 minutes. When I fix it, with the on/off button thing, I can go back and forth between 4K and regular channels - no sound problems. When I leave the 4K channel on continuously for at least 30-45 minutes, the sound goes away on the regular channels. I’ve been able to replicate the problem 3 times now. 

I’ve also noticed that the problem does NOT happen in my bedroom. The TV in the BR is also a Samsung and only about two years older than the TV upon which I’ve been experimenting. I have several DirecTV boxes and remotes, all the same. I’ll try rotating them and see if I can find a problem.

I don’t understand any of this.
