Sonos Arc audio keeps cutting out when connected to Samsung TV

I’m having same problem with my Sono Arc and Samsung TV (QA75Q70AAWXZW), audio cuts out every few minutes for 1-2 seconds. This problem started end of 2023. I also have Sub, 1 Amp connected to a pair of in-ceiling speaker in my livingroom. So this problem is pervasive, based on other’s report as well. 

below are screen shots of my TV and Sono System. Arc is disconnected, as I was trying to follow the instruction in the thread to disconnect and reconnect Arc and TV.

I followed the instruction below, and it fixed the problem. On the Samsung TV, I left the HDMI-eARC mode setting to OFF. 

Disconnect everything from the TV including the Arc and unplug the TV and Arc from power for a couple of minutes. Plug everything back in but keep everything disconnected. Be sure Anynet+ is enabled in the TV settings and set Digital Output Audio Format to Pass-Through and HDMI-eARC Mode to OFF. Run TV Setup in the Sonos app and follow the instructions. When the app instructs you, connect the Arc to the TV using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect any other devices to the TV.

Keep the HDMI-eARC Mode setting to OFF when using streaming apps. Set it to AUTO when using the Blu-ray player.

I am having the same behaviour for the last ~3months.

The sounds is randomly go to silent for 2-3 seconds at a time. This is happening with my samsung TV QN90AA.
It happen with any source (native app, cable box)..

Situation is a worst when eArc is set to Auto. 

I tried the workaround to unplug everything without success.. This was running fine for more than a year..

Any ideas?

Sonos Arc OS: S2

Version 16.1

Hardware Version : 1.27.1.11-1.2

(with Sonos Sub connected)

I left the HDMI-eARC mode setting to OFF. 
 

I unplugged all other sources - cable set top box, appleTV, switch, and didn’t connect them back until I verified the fix worked just with Samsungs internal app like Netflix or YouTube. 
 

Hope that works for you too. 

Thanks again for your quick feedback!

I tried it again and it seems to work now :)

Maybe I skipped a step last time or went to fast.. ¯\_(ツ)_/¯ 

It feel good to not have that silent drop for a whole movie.

Also having a Samsung/Arc SL issue. It only started a few months ago.

Very annoying!!

About ready to return my unit to Costco and go with a different bar

I totally understand your frustration.
You can try to follow the disconnect step posted earlier.

So far, it ‘s working for me. Already watched a couple of movies and a full tv show without a glitch :)

Good luck!

This should not be marked as answered. Samsung QN85. Audio cuts out for 3-5 seconds every couple minutes. 

The steps to fix it worked temporarily. Started happening again. A soundbar this expensive should not be having this problem. 

I have the same problem.  This is super frustrating with $1000s of dollars invested in Samsung and Sonos equipment. How is “turn off earc” (losing the cool functionality I upgraded to) the solution?  This is down right embarrassing to host an event and have the TV sound operate worse than any TV sound experience in my 40 year lifetime. Do better SONOS. 

I have been having these issues off and on for the past few years. It has gotten noticeably worse lately especially with my Samsung QN65Q70. Intermittent sound cutting out and short/brief sound skips and drops. Really Sonos??????? Why is this issue all over this forum and all over the internet. I have yet to see a fully satisfying resolution that does NOT involve some type of feature reducing workaround. I have other sound systems connected to my other Samsung TV’s and those sound systems have zero issues!

This has caused me to most definitely plan on NOT buying Sonos ever again. All this money for a SONOS ARC and it can’t seem to simply play sound (without the skips and interruptions) from my Samsung with HDMI set to pass through along with all the other recommended settings. And YES, I have tried all of the power cycling and resets. Sometimes it works, most of the time it doesn’t. And, when it does work, it’s only for a brief period of time. SONOS you’ve been nothing but a headache. I would never recommend to my friends or anyone else to buy your ARC.

The lack of sound consistency and reliability was just barely “tolerable” before but has been growing more and more intolerable! Please fix your issues!!!!!
