Lost surround and sub ( after update ?)

Trying this too. Didn’t have voice anything before. Just installed Sonos voice on the arc. Powered everything off for 10 minutes or so. We’ll see what happens. Not changing inputs, just different apps, audio formats.

Not holding my breathe, but who knows. I didn’t have a dropout from Fri thru Sun last weekend (blind luck), but on Memorial Day it did finally happen.

Here’s hoping...

I really don’t want to jinx it but this would explain why seemingly a lot of users do not experience the issue and they obviously have made changes related to voice control in the run up to the new voice assistant so if there was a bug/regression it could be in that code path

Going to install the Sonos Assistant and try it tonight, really hope this is it!!!!

be sure to do a power cycle after you enable it just to rule out any ghosts from a previous occurrence of the issue

not sure I understand how if the sonos voice is for music playback, how that affects the surround issues (movies, tv, etc.) when there were none before 14.6 update (with the speaker firmware I’m assuming).

but keeping fingers crossed :)

the theory is that there is some kind of bug related to HDMI-CEC that could cause an exception and break how the Arc communicates to the bonded speakers. when using a voice assistant additional HDMI-CEC commands are enabled (turn on/off tv, etc) which might avoid the issue for some reason

they’ve been working on substantial changes getting the new sonos voice control ready, so it stands to reason if a potential regression occurred it could be related to that and the timing lines up with the recent updates

if this is in fact the case it would at least help Sonos narrow down where the issue is and get a fix out

gotcha - thanks for explaining that. I’m no expert on this stuff :)

I wasn’t either until 14.6 came out 

lol - I’ve been switching apps, Hulu tv to Disney+, Paramount+, Amazon Prime… so far so good. 

man I hope this works

This has happened to me twice. Total mis-mapping of channels. Both times I was watching a trailer, and both times with sub and surrounds dropped out when I rewatched the trailer a second time
