Topping D10s DAC auto standby?

[Falco]

I've done a bit more digging, I might need to revert to uhubctl if it at all is available for RaspiOS....
Could that be something to integrate in MoOde, it seems some sort of support for USB standby is available in Picore player and Ropiee it seems

Can you provide links to how the other players implement USB standby? 
AFAIK its not part of RaspiOS.

Hi Tim, I need to look that up again, read something over at audiosciencereview.com

In the mean time I've also found this, will try that first when I'm home again.
