no volume control arc ultra after latest update

Its bedtime now, will try this tomorrow and report back thanks

Just a reminder, the Sonos Arc Ultra (and any Sonos soundbar connected by HDMI-ARC) gets the volume instructions from the TV set, which receives the commands from your remote. If it isn’t changing volume properly, the TV is likely not sending the correct instructions to the Sonos, hence why ​@Stanley_4 is recommending a reboot. 

Jjust did this and that fixed it, lol that simple "sir have you tried unplugging it and plugging it in again" 🤣 never had a problem for years that required me to do this but will remember this in the future thanks again Stanley!

Many units will reboot if power is interrupted for a fraction of a second, other units will not reboot until power is interrupted for a minute or two. I prefer the latter type because it avoids trashing a system’s setup if there is a momentary power glitch.

I tried unplugging and it didn’t work

Then I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, Sonos’ lawyers get sensitive about GDPR, I suspect.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

You do realize that this post originated two (2) months ago. So what update are you referring to assuming that caused your issue? You might also indicate if your device is iOS or Android.

It has nothing to do with an update. The tv remote was controlling volume and now it’s not. I just wanted to make it clear that I’ve already tried the unplugging solution. It sounds like I just need to call Sonos.

You should have started a post specific to your issue as this thread clearly has nothing to do with it. Please do that and you may get help from members; or call Sonos Tech support if that’s what you’d rather do.
