Lost surround and sub ( after update ?)

Its back again - triggered when moving between AppleTV and Amazon Prime.

Experiment over.  Brad 0, Sonos 55.

I’m sad that we as users having to go through multiple troubleshooting steps, resets, messing around with our internet setups when it’s not our fault whereas the company who pushed the buggy update is just sitting and watching this unfold.

One of the worst side effects of all this (apart from the obvious) is that you cut even decide to move away from Sonos and sell your kit to put toward a new kit. You would literally be selling this pain and torment to someone else.

We kind of really are sitting with an attractive Brick. 

Please push Sonos tech team to associate this to the parent case of subwoofer and surrounds drop out. It’s pointless raising concerns here, the more cases , the faster the resolution. I have been dealing with this since a month now. Even the last update didn’t fix it, I am aware they are working on something in the back end but they say we won’t know by when the fix will be ready. It’s quite difficult having to wait , so please voice it out on social media handles as well. The developer team needs to fix this on priority.

I spoke to a Sonos representative on the chat once again today and straight up asked for status on this issue. The guy knew about the problem and said that some users had had luck with using ethernet cable to the Arc. I tried, but no luck of course. He also said that they are aware of the issue and are working on it. 

I tried to get him to relay that they really need to get some more official information out regarding this as people are getting really angry about this, which he would try to. 

Today - after 5 day’s working - the issue occured again. So not making trueplaj adjustment is not solution.

What you think about WPA version? I have WPA3 now and as I know each device in WPA3 network is individually encrypted. Could it be reason that devices loose connection between each other?

I really doubt its anything network related. I suspect its some software issue that occurs sometimes when switch codecs

All of my wireless Sonos gear (Move, Roam) is WPA3 only and I had no sync or loss issues until 14.6.

@Corry P any interest in providing an update for us? I’m getting frustrated enough to consider returning my Arc and going back to my Playbar

Hi there, 

I have the same issue that often sub and surround are lost.

What I was able to perform several times now as a workaround was to switch audio to a TuneIn radio station playing some music for a few seconds and then switch back to TV sound again.

Then the sub and surround speakers work again for the TV audio.
