I have a sonos ARC and sound keeps cutting out for 1-2 seconds and then picks back up. My sonos was fine for about 1 week after purchasing but now the sound will cut out periodically. Here is my diagnostics number 103248445. How can I fix this issue?

Hi
Let us know what you have in mind with the advice above.

Is there a link to the article?
I am questioning why Wi-Fi interference would cause this issue since sound comes from the hdmi cable to arc, not Wi-Fi. To test I unplugged the surrounds and bass, so it’s just the arc. Turned on the tv, same problem with just the arc. When powercycling the arc, it works perfectly. For some reason if Wi-Fi interference were the problem, the problem would still be there after the power cycle or shortly after. This seems like an interface problem with sonos. Here is the diagnostic with just the arc. 1979548412
Agree here, wireless interference or not, I don’t see why that would effect dropouts over HDMI, WiFi should have absolutely no effect on the HDMI connection. Also since when did any device using WiFi not have WiFi interference, that’s a common issue, and if the Sonos ARC can’t cope without crapping out there is a serious issue with this device.
I am having the same issue, but not with the TV sound. It’s when I stream music from Sirius XM. Unplugging the device every few days to temporarily fix it is not a solution. Please advise when you will correct this problem.

Same thing happening for me - samsung Frame TV (2020 model).
I usually just unplug the power from the Arc then plug it back in and it works again for a day or two, but just like everyone else, I don’t think this is an acceptable solution for such an expensive soundbar.
I’m happy to submit a diagnostic report, but after reading the thread, it seems there’s really no point. I just have to wait until there’s an actual resolution.
Have the same problem with cutting in and out and believe that is a Sonos issue.
- It’s fixed when Unplugging and replugging the ARC.
this method is not acceptable and hence tried a couple of other methods after reading both of these work without the need to to do option A above.
have found a couple of options to remedy the issue every day. But still not acceptable.
- Going into advance sound settings on the TV and 1) switch sound to PCMI 2) Click the auto select sound for Dolby off and on. Then need to switch back from PCMI to auto once working correctly
- Just recently discovered that playing music from Spotify via my phone before turning on the TV avoids the issues. Currently my best solution. Still a pain but tells me it’s the ARC.
hope this works for others
Hi,
I have the same issue with a Samsung 90T, and I’ve tried all of the solutions mentioned over the last month or so.
Such as but not limited to; power cycling, removing all other devices, trying different input devices, checking settings on tv, updating firmware on tv, turning off Alexa, turning off CEC, checking the type and quality of the HDMi cables/ports.
I’ve submitted a diagnostic: 265717871
I’m happy to conduct further testing and provide any results.

Hi

I’m also experiencing this issue. I have a 3 week old Samsung Q80T and my Arc is a week old. It happened today for the first time. I turned my TV on and the sound kept cutting in and out. Had to power cycle my Arc to resolve it. I have my TV connected to the Arc via the eArc port. I will take a diagnostic the next time it happens.
After a couple of weeks of _not_ experiencing the intermittent audio problem with the Arc, I may have discovered a contributing factor. CAVEAT - I have a Samsung Frame TV, and I see several people in this topic with non-Frame TVs, so not sure if I’ve actually discovered a smoking gun. In any event…
Since my last post, in my efforts to troubleshoot, I switched on the “TV Autoplay” setting for my Sonos Arc in the app. Since that time, I have not experienced the intermittent audio problem. However, yesterday afternoon I switched TV Autoplay back to OFF, and that evening, when I turned on the TV, the intermittent audio problem resurfaced. I’m thinking that’s not a coincidence.
So, why would I switch off TV Autoplay in the first place? As those of you with Frame TVs are likely aware, the TV has a motion sensor that will turn off the standby art display to save power. If I’m playing music through my Sonos Arc (from any source other than the TV) and the TV art display has turned off due to no motion in the room, as soon as motion is detected, and the TV resumes the art display, Sonos apparently thinks that the TV has been switched on (i.e. the HDMI/ARC port comes back to life) and the Sonos music playback stops (which is behaviour you’d probably expect from Autoplay if you were actually turning on the TV). I noticed this back when I had my Playbar connected to this TV, which is why I initially switched Autoplay off. I found it annoying that everytime my art display came out of sleep mode, it would kill the music playback.
It would seem Sonos is probably doing exactly what it’s designed to do - detecting the state of the HDMI/ARC port into which it’s connected - but only when you have TV Autoplay switched on. The Samsung TV is apparently shutting down that HDMI/ARC port when it shuts down the art/standby display (due to the motion sensor), and wakes the port up again when the display wakes up, even though the display is only the standby art display, and not the actual television (if that makes sense). If the Sonos TV Autoplay is switched off, it apparently isn’t checking to see if the TV HDMI/ARC port is alive, and that’s when I get the intermittent audio, until I unplug/replug the HDMI cable (or power cycle the Arc).
Not sure what this all means in terms of resolving this issue. Might there be a way for Sonos to regularly check the state of the HDMI/ARC port whether or not TV Autoplay is switched on? It doesn’t seem quite right to me that Sonos is only detecting the power state of the HDMI/ARC port if TV Autoplay is switched on (if that is indeed what’s happening)
In the case of non-Frame Samsung TVs, I can only guess that the HDMI/ARC port on the TV shuts down as part of some power saving scheme as well, although not linked to an “art display” motion sensor.
Figured I’d share this information with the community as I hadn’t seen any specific references to the TV Autoplay setting when I scanned the posts. Curious to know if any of you experiencing this issue have noticed the same correlation to the TV Autoplay setting in the Sonos app.
I’ve also shared this with Sonos Tech Support.

Unfortunately, I always have the TV Autoplay option enabled in my setup, and I experienced the sound issue today. Perhaps that is particular to your setup?
Ah, ok. Well, there goes my exciting theory - I thought I was on to something.
It happened to me again this morning. I’ve submitted a diagnostic; 1286106442
I am also experiencing this issue.

Hi
Just to clarify, the sound on the ARC returned once I power cycled it. However as mentioned by others above, this isn’t a long term solution. It seems to happen for me when I bring the TV out of standby. The TV is a Samsung Q80T (UK version).

Hi,
I am having the same issue as others here, the only difference I see is that it grew in frequency. Initially it would happen once or twice per week, and now it’s every single time I start the sound systems to watch something on the TV. My Diagnostic number is 512796646.
Thanks

I can only agree with you. I have contacted the local support and they were nice and willing, but Murphy’s law doing it s thing the problem did not happen when I was on the call…. but the again the next time I powered it all. I’ll keep trying but it is surprising this does not create more ripples as I see so many occurrences of this problem being raised.
I have the same issue …m y initial Arc was returned to the retailer who was aware of other problems, said it was a manufacturing fault and replaced it. The new one was fine for 6 weeks until last night when it started happening again
my diagnostic fault number is 809839053
my retailer has referred it to Sonos but I am ready to take it back for a refund and get a Samsung soundbar ...its clear that this product is not fit for purpose and I am not willing to spend my time rebooting and reconfiguring what is supposed to be a premium product
the plethora of comments on here and other fora make it clear that this is a widely occurring failure rather than a random ad hoc failures

Reading through all the months of comments with customers experiencing e-Arc incompatiblily with the Sonos Arc and Samsung Frame 2020 model TV’s, SONOS HOW DO YOU FIND IT ACCEPTABLE THAT THIS IS STILL AN ISSUE FOR YOUR CUSTOMERS. WHY HAS THIS NOT BEEN FIXED . PLEASE CONTACT ME TO ARRANGE A REPLACEMENT SOUND BAR to replace the faulty one you sold to me.
I Lied - Another Update...so, in all my back and forth with Sonos, they ended up keeping one of my cases open and a very responsive and seemingly-knowledgeable support rep has been corresponding with me. One of the first things he said - and this was the first time I got anything like this from Sonos - is that there is a KNOWN ISSUE with eARC TVs, and with those TVs, the symptom is a periodic complete loss of audio. And they are apparently working with Samsung to resolve. My Samsung Frame TV is a 2019 version with regular HDMI/ARC (i.e. not eARC). And my symptom of the audio cutting in/out, like someone is pressing the mute/un-mute button every 1-2 seconds, is, according to him, not a common issue. This strikes me as odd, given there are so many posts in this topic, and others, that seem to raise the identical issue. And the diagnostic shows the HDMI/ARC port to be inactive when the symptom is occurring. None of this is novel - we all suspect it’s a software/firmware issue on the TV side (and apparently not just Samsung TVs), but just wanted to confirm with the community...for those of you with regular HDMI/ARC connections (not eARC), does your TV periodically [allegedly] shut down the HDMI/ARC port and you’re left with audio cutting in/out until you either hard-reboot your TV or unplug/re-plug the HDMI cable to the Arc? I told the rep to just go read a few of these topics in the community and he’d see I’m not alone in this, but they’re treating my issue like something unique, albeit with no real optimism for a solution. 
I have an eARC on my 2020 75” Samsung frame TV and I also have my sound cut in/out when I first turn my tv on in the morning. It happens every morning not just a couple of times a week. My kids have just learned to unplug the arc and plug it back in. I pre-ordered the arc system with sub earlier this year and it finally arrived July 2020. The sound is great but the connectivity issues are frustrating for the amount I spent on this system. I haven’t done any diagnostics with Sonos because I have no hope they will solve it. I keep checking periodically in these forums for a fix. I hope on comes soon

Hi,
I’m having the same issue, I’ve:
- Tried different HDMI cables in case that was the issue
- Power cycled the TV and ARC (work for a little while)
- Reset the ARC and set-up from scratch
- Removed surround speakers in case they were causing the issue
- Ensured TV (also new) is plugged directly into a LAN cable for maximum download speeds.
