Hi @jpcarey, thank you for the update.

I apologize I didn’t notice it the first time. Thank you for pointing it out.

I checked the diagnostic, I’m seeing the same errors. TV connection cutting in and out intermittently.

I can also see it’s receiving Dolby Digital Plus in the diagnostics.

To further isolate the issue, check if the issue persists during Music Playback and an Optical connection with the adaptor to the TV.

I won’t stop the return if you decided to go this route. As long it’s within the Money Back Guarantee period you should get your money’s worth back.

If you have other concerns, feel free to reach out. The community is here to help.

Just wanted to update everyone that swapping out to the optical out adapter seems to have resolved the issue of the TV sound cutting out on my Sony TV. I did see a few posts asking about music and I was able to stream music without any audio issues (AirPlay). Seems like this is isolated to the HDMI/eARC as the cause of this issue. The only downside to using the adapter is that now I have to control volume through my phone or an additional remote. Hoping Sonos has an update soon!

@Kyle A another 985001023. It has cut out at least 6 times today. I’ve used Airplay and never observed an issue. Additionally, before the ARC arrived, I had the TV hooked to a Sony AVR via ARC and never once had an issue.

Using process of elimination here, that leaves two possible faulty components: the HDMI cable Sonos supplied, or a hardware or software fault for the HDMI input for the ARC. I’ve noticed others have switched out the cable and observed the same results with the audio cutting out.

Since this appears to either be a hardware or software issue for the ARC, it would be great to get some insight on how and when this will be fixed. Otherwise I’ll miss my 45 day refund window while spinning my wheels swapping out the HDMI cables and submitting a diagnostic each day...

I have the same issue. I have a Samsung UN65TU7000F (2020) and using Rocketfish 4K Cables. It started from the first time, but I thought it was a cable issue, tried with different cables and the problem was temporarily solved for about a week. Today, I am having the problem again. Would like to know if its a software issue that will be solved with an update or a hardware issue to send it back. 

Hi @BoostinChick, @jpcarey and @azavalao welcome to the community.

Thank you for the update @jpcarey and @BoostinChick.

@BoostinChick, there’s is a remote setup in the Sonos app for the Arc to recognize an IR remote.

Setting > System > Arc’s Room] > Remote Control Setup.

@jpcarey, as of now there’s no estimated time given on when it will be fixed and don’t worry if the 45 day return period is up; there’s still the 1-year warranty.

I checked the diagnostic, still the same errors as before.

@BoostinChick and @jpcarey; For the HDMI connection issue, I would recommend calling our Phone Support. 

They’ll have more options to address the HDMI issue; they can also escalate the issue further if need be.

1 800 680 2345 Monday to Friday from 10 am to 9 pm ET.

@azavalao, I would like to confirm with a diagnostic; if the Arc also shows the same errors.

Please take a diagnostic in the Sonos app. Settings > Help & Tips > Submit Diagnostic.

After getting the diagnostic, test music playback and with an optical connection.

If it’s all the same with the others, I would also recommend calling our Phone Support.

We apologize for any inconvenience this issue has caused and thank you for your patience.

I have been having the same issue for months now. 2020 Samsung Q series with the ARC. I have spent HOURS on the phone with Sonos Techs and submitted many diagnostics reports and the only solution offered to me was to unplug the Arc and ALL of my TV inputs. Then Plug the Arc back in followed by each of my TV inputs (EVERY TIME). Since the issue is re-occurring, I was told it must be that my HDMI cables have “Too much capability” and they are passing different signals that the ARC doesn't know what to do with. So, I need to swap them out with “Dumb” ones. REALLY???? What a joke. How was this stuff not caught during Beta testing? I wish I had a way to recoup my money and time spent on this. 

Spend all this money for this kind of support and response. SMH

Hi,

I have emailed my set up details now. I have removed an old Samsung Bluray player from my set up and since doing so, have found that I cannot replicate the sound issues (cutting in and out) again.

I am having exact same issue: sound cuts out every 4-5 secs for one sec

Brand new arc

Brand new Samsung QT70 

I have to unplug and re plug Arc to fix, occurs daily 

This is clearly a Sonos issue. 

I have been Sonos user for over 5-6 years. i have absolutely loved my SL Play Ones from day one, to the point where i bought four of them, I have recommend Sonos to every person I can, i finally decided to commit fully to Sonos as my entertainment system and bought an Arc, Sub, and boost. I understand new products can have issues, but I am pretty disheartened with Sonos products after such a financial commitment, hoping this can be resolved

Just bought Arc, sub and surround speakers. Sound is great and then turns on and off. Unplug and restart and works again. Then stops. I have a Samsung TV. Just return the system?  This seems like an ongoing issue with no real fix. 

Hi. I have purchased the Samsung Frame 75” TV (2020 MODEL). I also have the Sonos ARC, Sonos Sub Woofer (Gen 3) and the 2 Sonos One speakers all purchased 2 weeks ago.

On the Samsung TV i am not able to choose e-ARC auto in settings. Is this a Samsung issue or Sonos?

Also from time to time when I turn the TV on the sound with cut in and out. The only way I can fix this issue is by unplugging the Sonos ARC and replugging it back in. Once i do this the issue is fixed. 

Do we know why this is happening?

I am a dealer and I have had some issues with audio as well on the Sony A8H model. I used the optical adaptor to bypass the HDMI ARC from the TV to verify it is not a EDID issue. The customers Audio still drops from using the TV apps as well as the HDMI input from the cable company. I spoke to Sonos tech support yesterday and they said they are working with Sony. They did not say however hows fault this is nor did I get a time frame on the fix. I have my customer bypassing the ARC altogether to see if sound still cuts out from TV speakers. 

Just want to say I had the exact same issue on a Samsung TV. This solution worked for me as well. 

Thanks for the reply. However I have to unplug and plug in the arc everyday. I don’t think that’s right. Go figure!

Um, I’m not paying $800 for a sound bar and un plugging it and plugging it back in every 3-4 days so it works without disruption.

i need a fix.

now.

Same problem, here. Among other problems.

Long time Playbar user. Zero problems. 
 

Intermittent cut in sound. Wall mount. Under Sony 65” X950G (2018). Stock Sonos cables. eArc connection.

Hope there’s a simple fix.

Had the same problem with both Arc and Beam on Samsing TVs.  I switched to using the optical cable on both and the problem has stopped.  At ;east no sound drop out.  Creates a hassle with using the remote to change volume, but do that with Sonos now.

I hope not. Got the Arc for the eArc, Atmos, one remote, etc. 

thx 

Are they using the Sonos supplied HDMI cable? I have read that they possibly have a bad batch of HDMI cables as well. I am using another HDMI cable + the optical adapter and I have not experienced any more cutting out issues for over a week now. I also noticed that my Sonos system has updated to 12.0.3. I tried eARC again on 12.0.3 but ran into the same issue of the audio cutting out so I swapped back to the optical adapter. Good to know that Sonos tech support is claiming they are working with Sony on this.

Optical seems error free. But opposite one of the reasons I bought the Arc—for the eArc, single remote with Sony native apps, etc.

Switching from Auto 1 to Auto 2 or PCM returns the sound. Really odd. 

Has there been an update that don’t know about? All of a sudden mine has been worked my perfectly. Two week straight and no further issues. Prior to that my ARC was cutting out every 3 seconds until unplugged and plugged it back in. Would do this once a week. Now I have no issues. Fingers crossed. 
 

I have Samsung Q8DT TV 2020 with eARC. 

Hi all,

Glad I came across this.

Mine has been working 100% perfect and still runs fine on Netflix, Disney+, std digital TV.

The first time I tried to use the Nintendo Switch I noticed it cutting out. It does it constantly and is worse the more is going on the screen at the time.

I have a OLED55B9PTA running eARC

It’s funny that you mention the Nintendo issue. Mine didn’t start having problems until we started playing on Nintendo Wii. Had family in town and we played mario kart and immediately started having issues. Xbox and PlayStation work fine. Why would that be?

Posted earlier on this issue.  After all the connection issues I gave up, took the system back to BestBuy. 2 days later I got a Bose 700 (because it is also white). Using the ARC connection, I have no drop outs on the Bose, which were not related to the source, which points to the sonos.  Noting that both the Bose and Sonos have difficulties reconnecting back to the TV system after using airplay.

The Bose has to also go back because it appears to be a referb unit, rather than new?

I would probably swing back to the sonos if there were any signs of a fix?

I have an issue where the audio cuts out on DTV when I change channels.  Have to turn TV on/off to reestablish audio, then problem will resurface almost immediately after changing channels.

Setup is Sonos arc, LG 86” UN8100PTB (which is new), using HDMI eARC.

I changed TV setting to disable eARC, i.e. using ARC, problem solved.

Obviously wanting benefit of eARC, re-enabled eARC and explored other solutions. 

Changed TV audio output setting from Auto to Pass Through, problem solved. This doesn’t make sense as the pass through should only affect external audio sources, such as BluRay etc.

I’s continue to monitor and see if problem reoccurs.

Did create my own thread on this issue but best to use this thread, I thought I had solved it by changing HDMI cables, but issue persists with audio dropping when exiting internal apps or external devices back to tv tuner.

Also I sometimes get a quick 1 second audio dropout not long after turning tv on, while on tv tuner.

Also for the first time yesterday I was watching the freeview tv tuner and the sound just dropped altogether after a while, I had to switch to another HDMI port and back to tv tuner to get sound back.

TV is new LG CX, and I use eARC and passthrough settings.

Clearly something wrong with this ARC, please Sonos, sort these audio issues out.
