Sonos Arc isn't compatible with 2020 Panasonic HZ OLED Series with eARC

Best ATV 4K setting

It appears when you choose any of the HDMI inputs.

Thanks, I have my Apple TV set up using that. The only reason I’m trying to get my native apps to play 5:1 is for the calibrated Netflix and the extra BBC IPlayer options available on the native app that are missing on the Apple TV. I also prefer the picture. It is also bugging me big time as to why I just cannot get them to work properly when I have everything set up for it do so!! 

I think I read somewhere the Apple TV uses a different digital signal than native apps and I’m wondering if the tv cannot convert the signal to something the Sonos can use… but they work for you so that doesn’t add up!

Just done a factory reset but still the same. I will have to get in touch with support and do a diagnostic and see if they can find anything… I’m expecting them to say its the tv!!

...got to say, regardless of the teething problems with the Arc I’m loving the HZ1000 though, the picture quality is just exceptional!!

...and thanks for all your help!!

Let us know once you figure it out :-)

for me everything worked out of the box right away 👍

dolby vision IQ works good. Sometimes i switch to Dolby Vision Dark but cannot see much difference in low light conditions.

Soooooo I think I have finally found out the problem. It’s the viera link on the TV isn’t communicating with the Sonos. For some reason when I switch viera link off then turn my earc setting off then back to on again the tv gets perfect audio and its in full Dolby atmos (I tried this out using the TV’s Netflix app)

The problem I now have is that with viera link switched off my TV remote cant control the sound on the Sonos, it is effect disabled.

Any ideas how to fix this? 

I got his turned on.

can adjust Arc volum with tv remote.

I’ll have another look in my tv settings..! 👍

Hi, Its been a week or so since I was last on as I have been in touch with both Sonos and Panasonic regarding my sound dropout issues when using the TV’s native apps like Netflix.

Trust me when I say this its walking through treacle trying to sort anything out with Panasonic, its nigh on diabolical customer service, all I have been getting is one line ‘Tech support answers at best’. Sonos have been fantastic in comparison!

Anyway, my latest reply from Panasonic in response to the lack of sound through native Netflix etc is this:

"The sound bar is a 2.1 which is the same output when using PCM, the issue is the audio codec that Netflix uses, PCM fixes this issue"

I have already told them that it is a 3:1 system as I have surround speakers!! 

Can anybody clarify if this Panasonic statement is true or false please?

Honestly this whole situation has become a complete mess!!

...I also don't get any Netflix Audio Codec problems when using 4K Apple TV either it comes out in Dolby Atmos 

Weird

i have same equipment (tv and soundsystem)

no issue

atmos through nativ app and ATV4K

do a video of your tv settings and post?

can compare to mine.
