Hi There,

 

Please I need some ideas.  I have a Samsung 98 inch Neo QLED QN90A (QN98QN90AAFXZA) and a sonos ARC with two ERA 300 for surround and 2 Gen3 subs.  The Arc is connected to the tvs EARC port.  I get sound find and I am able to pass through Atmos, and dolby digital plus and others. I tried to stream from my nvidia shield 2019 and via plex I get sound cutting out. I have tried it via netflix same thing.  I still get the audio cutting out on Youtube and plex on the native TV.  Here are the steps I have tried to fix this:

 

1-Replaced all HDMI cables

2-Tried different input ports for shield

3-Replaced my ARC with a brand new one (up to date with latest firmware as of 4-27-2024)

4-Replaced my shield with a 2nd one around the house(up to date with latest firmware as of 4-27-2024)

5-Tried testing it directly from tv app vs shield same issue

6-Tried messing with the settings on the tv like earc auto and off, pass-though on and auto

7-Adjusted the delay to sync the earc( this seems to help but not fix the issue)

8-I tested the adapter of toslink with the hdmi and I think this works but is not viable solution as I cant get Atmos or control the sound very easily

 

The only thing I can think of is that maybe the port is bad on the TV.  Please someone out there has to have a solution.  At this point I am willing to buy anything to fix. I have already spent a ton of time and money and I cant get to the bottom of the issue.

 

 

 

Try this:

Disconnect everything from the TV and unplug the Arc and TV from power for a couple of minutes. Plug everything back in but keep everything disconnected. Make sure Anynet+ is enabled in the TV settings. Run TV Setup in the Sonos app and follow the app instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC/eARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect your other devices to the TV.

And set the TV to these settings:

HDMI-eARC Mode: Auto

Digital Output Audio Format: Pass-Through
 

If the audio is still cutting out after following the steps above, set eARC Mode to OFF.

well that seems to be working.  WOW. Thank you.  one thing I did is add a delay to the group setting to Medium and so far no cut outs. I think with Sonos you have to run the TV set up even if everything seems like its working good. I didnt run that.

 

Edit: Spoke to soon.  Its doing it again.  Ughhh
