Any update ?
I have an Sony 950G and I want this issue fixed before buying the Sonos Arc.
Thanks.
I too have Sonos ARC audio dropout issue with Sony 950g connected eArc HDM at least daily once.
Noticed that this is happening only in Dolby digital plus audio output. Try with Dolby digital and let know. I don’t se much difference in audio output on these 2 formats
In general if audio drops out then no need to switch off either TV or sound bar instead just do some actions like change Digital audio out to Auto 2 or PCM under Audio output and change back to your original setting that will pick sound again
I am always play with auto 1 . So whenever issue happens then I will change to auto2 Or PCM and then change back to auto 1 on the fly without turn off content watching or anything

First time in a week the sound has dropped off again on my arc! It is the first Sonos speaker I have had issues with in 10 years, gutted, given how much this thing costs.
Reporting back, the Simple IP Control didn't fix the sound issue. I just had to restart my TV to fix it... Please keep us updated if there is a new fix.
No need to restart your equipment. Go to your TV’s audio setting. Switch between TV speakers and external speakers. That should temporarily fix the issue.
Mine did it again today. The new Sonos update hasn’t helped and all of the above solutions doesn’t work unfortunately.
Same with my LG CX, occasionally drops sound and doesn't come back, exiting internal Netflix app and back to TV tuner sometimes doesn't give sound either.
Updated to latest 12.0.5 but still the same.
I’m not blaming Sonos for all these issues, for all I know it could be the LG TV as well, in any case hopefully all the companies can work with Sonos to fix this!
For such an expensive soundbar its really poor having such issues.

Bugger, that’s annoying, I updated yesterday and have not dropped out yet so really happy.
I have the new update too. But it didn't fix the sound problem. :C

No nothing ended up being a long term fix. However Sonos released an update yesterday, since I have had no issues, it appears to have fixed! Which is awesome news! Check your updates. 👍

Thanks 85D, I am not sure I want to go the Roku route, but great that it is working. I saw on another community post that Sonos have now acknowledged this as an issue and are working on a fix, so I am hoping this is sorted pretty soon, its been a frustrating couple of months changing all sorts of settings and thinking it was different things.
I am a fellow Sony Bravia owner (950G) who tried everything I could find. Currently problem free for 3 weeks and counting using Roku Ultra for streaming instead of the native apps on the TV. I am connected via HDMI / eARC with a brand new 8K cable (which itself didn’t fix the problem). Might consider giving it a try? I have another week before the Roku return period runs out, so fingers crossed...

Hi Oriboaz, the sound stays off until i actually pull the plug out, just turning the tv does not work. I am only trying atmos plugged into the earc setting on my tv and using the cable provided by Sonos. The arc is wall mounted cables through the wall. To be honest it’s a pain putting new cables through the wall so would rather not even try a new cable. We should not have too if it’s the one provided. Cheers stuied
These drop offs of sound:
1. does the sound come back immediately, or is it silent until you do some action?
2. Do you know if they happen for all sound formats, or only for Dolby Digital Plus?
3. Do you use the stock HDMI cable?
I have a Sony TV, without eArc. All my sound is via Apple TV 4k, which outputs Dolby Digital 5.1 (not plus). With the stock cable, sometimes the sound will partially drop off for a split second (it will become weaker, but not completely silent), and them come back immediately. I replaced the stock cable with a different HDMI cable (thicker), which improved things immensely. Since replacing the cable, in about two weeks I had this split-second drop off occur only twice. Now, it should not happen at all, but at least now it’s infrequent enough that I can live with it for a while.
Now, you may think that an HDMI cable does not matter, but it can. The digital data going through it is encoded, and the receiving device needs to decode it. If the cable isn’t properly shielded, there may be interference that can cause problems.

It is so random for me, I love the sound quality so will put up with it for now. I agree for the price this should acknowledge and a fix incorporated ASAP.
Ian101181I understand. Sonos arc has Atmos capabilities .
It is actually my first Sonos and I’m disappointed. I switched from Bose. So here is what I tried and is working so far. Go to your TV’s audio setting. Turn eARC to Auto and switch digital audio output to PCM. Mine dropped every couple of hours and ever since I made these changes I haven’t had any drops.
tried all settings some reduce the issue but the sound drop still happens and I also refuse to spend £800 on an Atmos sound bar to run it in pcm

I had this issue since the arc was launched. its gonna need a firmware update as nothing else can fix it. at first I thought it was Sony's fault but looking through the posts on here it seems a lot of other TV brands have the same issue, but at least Sonos are now looking into it hopefully we get a fix soon.

Unfortunately oriboaz suggestion does not work the sound has still dropped off. As such there is still no solution, Sonos and Sony remain quiet. Pretty expensive bit of kit to actually not work every time all the time, definitely a Sonos first for me (long time Sonos fan!) . Thanks Oriboaz it’s good to get any option to try and resolve.
Hi Stuied, I appreciate it if you can let me know. So far I’ve turned eARC to auto on my TV and set digital audio out to PCM. If this doesn’t fix the issue I’ll try your method.

Hey Babaee, try Oriboaz settings change for your TV. I updated mine yesterday and will report back if this stops or doesn’t the sound drop offs. Definitely worth a try. Mine was intermittent and not regular, but perhaps twice a week which was getting annoying. Cheers
I think it has something to do with the Sony TV’s latest update. My brother’s issue started after he updated the Sony TV.
Hi,
My brother and I have the exact same issue. We both have Sony g950 and Sonos arc. It seems like every couple of hours randomly the Sonos arc stops playing TV’s sound and the only way to fix it is to unplug them both. Did you ever figure out how to fix the issue?
