No sound XMC-1 when switching inputs

[sastone]

It's become a daily issue for me. When I switch from one input to another I will not have audio and will need to completely power off and reboot. My TV is assigned Input 1, Mac mini Input 2, TT Input 3, Apple TV Box Input 4, etc. If I'm listening to an album and then switch to watching TV there will be no audio. I can switch to another input but will still have no audio across all inputs. I'll have to completely reboot to get audio. This does not happen every time but it does happen daily. Apparently there is plans for a firmware update to fix the issue but I've now been waiting nearly 2 years. Any thoughts?

When you listen "to an album", is this when using the turntable? And if so, is the display On or Off when listening to the turntable?

I'm sure it's just a typo, but you list the TV as being Input 1? Please explain. What is connected to the two Outputs?

As a matter of course, it's always good to know which HDMI board is installed? This may come into play for diagnosis/fix. The "original" boards were either V1 or V2 HDMI 1.4b, and the "upgrade" board from 2018 is the V3 HDMI 2.0b/HDCP 2.2 which is 4K capable.
