Nano crashes when used as audio interface with 9v power plug connected and usb C cabel connected to my macbook/iphone.
It freezes completely with no output sound or sound starts dropping.
NOTE: When usb C to A is used (which doesn’t power nano alone) and 9v is connected - then it works fine.
I think it’s power related issue as usb c is capable to power/startup nano and when 9v is connected in addition - it doesn’t know which power source to use.
