Hi 

I don’t know if my issue is related to the 14.6 update but I noticed today that I had no sound from my surround (play 3) and my sub (Gen 2), only the Arc is working They are still present in the app under the my System view but now sound which every sources

When I reboot each of them, the sound comes back temporary, but when I switch to another source or audio format, thé Sound disappears again. Tried several times, same behavior

Thanks for your help

    I have a Gen1.

    So you observed that it became more unstable when you connected your first gen AppleTV? I looked at the specs for Gen1 v Gen2 and it’s (apparently) only Gen2 that supports eARC. Can’t find the link now, but it just struck me that you had increasing instability when you plugged in the Gen1.

    When I’ve had the gen 2 connected alone, I have been very stable. When I connect the gen 1 also, my stability craters. Can’t say for sure if it is the gen 1 that causes issues, or having 2 Apple TVs connected to the same system that causes the issues. Gives me some more things to trouble shoot though

     

    With the Gen 2, when you say stable, you can bounce around from app to app while watching videos and not lose the sub? That is what seems to generally trigger it for me.

    Yes, I’ve been stable for as long as 2 weeks without a dropout on only the gen 2. Every time I connect the gen 1 as well, get a ton of dropouts

      OK, something weird has occurred. (NOTE: no false hopes please, it's too early).

      • Today I went out and purchased two new HDMI cables (2M 8K Sandstrom) to replace my 3M 8K Maxonar. Replaced the connections to the AppleTV and Sonos ARC. (Notwithstanding that my previous cables had been working just fine up to April). 
      • I (through some weird and rediculous logic) moved the Apple TV to HDMI PORT 4 on the TV, from HDMI PORT 1. The ARC is in HDMI PORT 2 as that is where the eARC capability resides. (Note, all HDMI PORTS on my Panasonic produce 4K and are enabled for 4K in the settings). If you want to know my silly reason for moving the HDMI PORT, it was because I wanted to experiment with the TV PORT being lower than the ARC PORT.  There, I told you it was silly, but I am getting desperate. 

      I have spent two hours flicking between Amazon Prime, Apple TV, Netflix, stereo trailers and Native TV and I cannot replicate the issue. It's usually broke within the hour, but now I cannot entice it to disconnect the rears and subs.

      This does not make much sense to me. And this needs a lot more time, at least 3 days of no issues. But I am going to keep going and will report back. The reason I am progressing with this is that in the back of my head there are people out there who don't have the issue. So I keep thinking ‘there has to be something I can do!’. 

      As said, too early to tell, but I'll let you know how I get on. Maybe another false hope…...

            Could it perhaps have been just one of the HDMI cable(s) had developed a minor fault, rather than the change of TV port, or did the two new cables fail, when you used the original port setup - or is that something you are still yet to test?

            Sadly it went again. Darn. Back to the drawing board.

              I guess that rules out the HDMI cable being faulty then…

              Almost immediately after people post here saying ‘so far, so good’ …the issue then suddenly shows up again.

                  Did you remove all the other devices connected to the TV, leaving just the Sonos HT device and the Apple TV (with the CEC-less adapter) connected …and did you disable CEC on the Apple TV?
