Volume on TV/Beam always resets to zero when TV turned off/on.

I had same issue with my Arc and LG oled cx (connected via earc) every time I turned tv on arc volume was at zero. I fixed this issue as follows…..

opened my Sonos app

Select App Preferences

Unchecked Hardware Volume Control

Set volume with tv remote then turned tv off. Turned tv back on and volume on Arc

was where I left it before. 

Yes. Thanks for this, as it also worked for me. Since initial installation of the beam it has worked until we lost power on the Beam ( a cleaning even :-)). Maybe this power loss resets TV autoplay setting in the app.

Anyway, thanks for posting this.

Hello @chevyman142000,

Welcome to the Sonos Community and thank you for reaching out with your question. 

Do you know if your Apple TV is passing audio to your Beam via Airplay or are you sending line-out audio to your TV and then on to your Beam?

If you could submit a diagnostic report and include the confirmation number in your response, I’d be happy to take a look at it.

Here's how I fixed mine:

1 opened app

2 select system

3 select your device (beam in my case)

4 turn on TV Autoplay

Just as a note for others who stumble on this thread, and use a Harmony remote, a while back Logitech/Harmony added a volume setting to the process of turning on a TV, as well as changing inputs. It’s worth double checking those settings in the Harmony setup app. I had to make some slight adjustment to one of my remotes, as it was setting the volume to zero when changing inputs, but not when turning on the TV. 

Also having this problem - New Sonos amp, Sony TV, HDMI Arc - whenever I turn the TV on the volume is set to zero.  I see this thread is old, but I’ve seen no actual resolution or solution to this problem….

Clarification:  I checked “TV Autoplay” and now if I turn the TV off and on, the volume comes back which is great, however if I am playing around source through the Sonos, then come back later and turn the TV on, the volume is still zero. 

This is quite an old(ish) thread, but there are a number of suggestions in the posts here that appeared to fix the issue, albeit that was 3 months ago - have you perhaps tried the various fixes that are mentioned here?

I’m having a similar issue with my Beam, AppleTV, and Samsung TV. If I pause something on the AppleTV for a little while, the volume will go to 0. Seems to also do it when switching inputs from streaming music over to TV. Any solutions or ideas as to what is causing it?

I'm also experiencing this with the beam, the volume becomes muted whenever I turn off my TV using Google assistant, but not with the remote.

@Jean C. I think it may have to do with when I switch the Sonos 5.1 system to music and then back to the TV.  I’ve noticed a few times where the TV does hold the previous volume level before turning off the TV.  I will test it out later.  

For my Roku and my TV, I use a Harmony Hub Remote.  I don’t put my Sonos onto my Harmony since my TV has ARC and when I turn the TV volume up and down, it transfers that to the Sonos.  

Hi @Borreboy 2.

Welcome to the Sonos community and thanks for reaching out to us. 

I would like to recommend following the steps indicated above which includes replicating the issue and submitting a diagnostic so we can further check what might be going on with your Sonos Arc. Please take note of the confirmation number and let me know.

Please do not hesitate to reach out if you still have further questions or concerns. We are always here to help.

Thanks,

@evangallo,

Are you using just your TV remote to turn off the TV or are you using a voice assistant or harmony remote to turn off the TV?

Can you include the make/model of your TV so that we can see if it is a “feature” within the TV itself or due to a firmware update on that device?
