[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] adi2500:
USB DAC

[MENTION=5250109]rainforce279[/MENTION]

can you tell me if i can use an usb dac in general with santoni? because ive managed to kill my headphone amp ic while building a distortion pedal for my guitar amp. now my left channel distorts at volume levels which i w#would use, so i got an usb dac/headphone amp from fiio #, so that i can enjoy my music again. only problem is, that if i connect it with an otg adaptor it just gets charged, but isnt getting used as audio output.

Can you have a look inside if you can fix this with a kernel driver or if im just acting stupid?

Infos i got with the app "usb device info"
