I recently bought a small DAC by Donner that's usb powered by phone and I can't seem to get my phone to recognize the DAC. I get a notification that says "charging connected device via usb" with other options unselectable but the DAC itself doesn't power on. it works great on my gf's iPhone and on my computer. I've tried resetting the USB permissions, I've added storage permissions to the Samsung USB-c headset app, and tried restarting the phone with the DAC plugged in. no reaction other than the notification on the status bar and the phone speakers stay on.

Hi @ces91 ,

this may be not compatible with the S21. I would recommend getting one of our Samsung adapters from this link: https://www.samsung.com/uk/mobile-accessories/type-c-adapter-ee-uc10-ee-uc10juwegww/?merchant=17946&...

I have the same issue with my S22+Ultra. This is definitely a Samsung thing as this worked before the last update. Nope Tidal never asks to slow access to DAC because Samsung is trying to charge it and not just recognize it. Add you said, no option to change it to Audio like they had in the past
