Have a quick "normal or not normal" question on my JDS cmoybb.
 
When I turn it off (still connected to Schitt Modi DAC), there is slight buzzing sound in my headphones. The sound persists - it's not transient.
 
No sound at all when the switch is on but at low volume.
 
Running off mains power (non-rechargeable version).
 
Any help appreciated - thanks.

 
Sounds like a ground loop issue. Disconnect the AC adapter and try battery instead - if the buzzing disappear, that will confirm it is ground loop. It should be fixable by using a ground loop isolator or an USB isolator.

Thanks for the feedback - it is a ground loop.
