Mute button on volume tile not functional

Hi Hubitat crew, I finally got around to adding my Denon AVR to Hubitat and I found that the volume tile doesn’t have a functional mute button.

I know it’s not my AVR as the mute button on the Media Player tile does work.

@bobbyD can we get this looked at please?

What's the status of this? I can't mute my receiver -- and mediaPlayer is not applicable with its extra buttons.

The entire Denon integration is broken now for me, it isn’t getting state upgrades or able to control volume etc.

I know it isn’t my AVR as I was able to get it wiring via Home Assistant.
