[M-CR611] reporting wrong volume and mute status

[rapiertg]

Hello,

Marantz M-CR611 works almost great but it seems this device handles reporting status in some different way. Ex changing volume and mute from denonavr works however state is never reported back correctly. Ex. with help of denonavr-cli:

[desktop test]$ denonavr-cli -H 192.168.6.26
Power: ON       Volume: -56.0 dB         Input: Media Server
[desktop test]$ denonavr-cli -H 192.168.6.26 volume up 4
-56.0
[desktop test]$ denonavr-cli -H 192.168.6.26 volume down 3
-56.0

It happens for volume and mute - those are two not working so far, rest of status looks ok. Before I moved to HA I also reported it to openhab and they were able to fix it with this commit. Maybe it will give some hints.

Let me know if some more info is needed.
