Question regarding individual volumes + unjoin bug/problem

[kyme32]

Hello, I have the following setup card

is there a possibility to add volume bar for individual media players beside its name(on the right side of the name)?

only thing that i've found is sync_volume, but no posibility to use speaker_group future and have individual volumes.

Also i've noticed that when i try to turn off(unlink a speaker) the unlink is successful, but card remains in on position, after a refresh of the page, everything is as it should and the speaker is off

All players are linkplay, 1x wiim mini(front) + 3x audiocast m5

I have mini-media-player v1.16.9 installed
Linkplay component by nagyrobi V.3.2.1
