@Plortedo -
The volume indicator is handled by the TV itself. As such, it might be a good idea to take a closer look at the owners manual or
the LG Community for some pointers to see if you can get that to come up. Some TV's automatically turn this off after changing the audio output.
Let us know if you find out any new or helpful info!
I have the LG B7 and this also happens on this TV.
If you do find a way to get it working please lets us know. as i like to see what volume the TV is at
i just use google now - Hey google volume 8%, 10%, 13% and so on.
Alexa i could not get the % working and only volume up and down seem to work but it seems to jump up (or down) in volume and at night times where i have a young kid can be a bit frustrating (to be fare i am new to the beam/sonos)
Like @Keith N said i think the TV turns it off when using a different audio output. as it is the sonos beam you are turning up and not the TV volume. when you change the audio back to the TV (with the sonons still conencted) you the the 0-100 bar back (note no sound on the beam of course)
I posted this to the LG community as well here. Will report back if I find a solution there.
