ALSA error broken pipe always after receiver off/on


I am running Volumio on a RPi4. The RPi4 is attached via USB to my Emotiva RMC-1.
I am using Audirvana as a player, feeding music to Volumio over UPnP.

This works awesome, until I switch off/on my receiver.

I am always getting the following error then.
Failed to open “alsa” [alsa]; Error opening ALSA device 'hw;5,0"; snd_pcm_hw_params() failed: Broken pipe

Currently I can only fix this by either rebooting Volumio or by re-plugging the USB cable.

The log is here:

Help would be much appreciated.
Happy new year!

I also tried this with the RPi3+ by now, same problem.
Anybody has a similar issue or knows why this is happening?
