Bugger, that’s annoying, I updated yesterday and have not dropped out yet so really happy.

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.

Mine did it again today.  The new Sonos update hasn’t helped and all of the above solutions doesn’t work unfortunately.

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.

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. 

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

Any update ?

I have an Sony 950G and I want this issue fixed before buying the Sonos Arc.

Thanks.

issue is not fixed and no update yet 

tried below and now drop off issue reduced and rarely happening now.

1. Connect Sonos S2 app to  2.4 GHz channel 6
2. Change 2.4 GHz  WIFI router settings from Auto to channel 11.
3. connect your TV Network also to 2.4 GHz. I faced lot off drop offs when connected to 5G. I suspect may be my 5G WIFI signals were not healthy in where my TV placed. After connect my TV to same network as ARC (2.4) it is reduced lot.
4. Disable TV Audio output- Audio system prioritization

Hi @Krishma M 

The problem here is that there is no fix for the Sony 950G and I really hope that Sonos is talking to Sony to find a solution. I spent a lot of money on my Sonos system and it should be compatible with all the well known brands like Sony. Using DD instead of DD+ is not an option for me because it doesn’t support Atmos.

Hi @method_ben, thanks for your response. We understand where you all coming from and we are working on it. We’ll let you know here once we have an update available. Appreciate your patience and understanding.

Any updates so far? 
 

Audio keeps dropping... 3 times in 1 hour while using the Netflix app on my Sony XG950. 

Is it the same issue as described in this thread? https://en.community.sonos.com/home-theater-228993/arc-tv-sound-cuts-in-and-out-6842963

No it’s not the same issue, same outcome though…. audio not working.

I have no issues watching television using my arris digital decoder. As soon as I switch to Netflix and watch a high audio/video it starts cutting out. Rebooting is the only thing working right now… and it’s highly annoying considering it’s €2500 entertainment system...

I have the Sony 75x9500G too, with a Sonos Beam, and its been dropping sound for a year now. Connected via HDMI Arc. 

The only way to get sound back is to reboot the TV through the settings. 

Should i just give up on HDMI Arc and connect via Optical?

Not sure this will help but saw this on a Reddit forum and it’s how I have it set up on my Sony af9.

hdmi 3 output (which is what the sonus arc should be connected to for eArc): set to standard and not enhanced (apparently Sony says this is the issue), all other hdmi ouputs can be set to enhanced 

earc: set to auto

pass through: set to auto

I have a new TCL 65" Class 4K UHD QLED Roku Smart TV HDR 6 Series 65R625 TV and just bought an Arc and Sub. I'm having the same issue where the audio randomly drops at least once a day. If I reboot the TV it comes right back but this is so disappointing. I bought sonos because my brother has the original sound bar and sub and it rocks. This was pricey but I was so excited to get it only to find it's not what I was hoping for. Is there a fix for this?

@Bpf12158 Have you tried using a different HDMI cable?

Not yet. I am using the earc hdmi cable that came with it. Are you familiar with this problem? I'm so very sickened by this. Its happening right out of the box and this system was so expensive

Does the audio drop out no matter the source? Are you using any external media devices? What firmware version are you running on your TV? Can you send photos of your TV settings?

My only source is my TV. I have a Roku OS so I can stream directly from it or watch cable from it. No other source is attached to the ARC. My software version on the TCL is 9.4.0 which is current. The build is 4200.

Did you set up CEC and enable HDMI ARC on your TV?
