Hello, I have a problem with my Fiio K3.
This USB DAC was running for about 2,5 years on my pc.
Then without any reason the device stopped working while I was using it for playing music.
I already tried the device on another hardware (Macbook) where it works without any problem.
Changing USB-Cable or the port does not help.
I also tried to change the following parameters under /sys/module/usbcore/parameters/:
use_both_schemes → Y
old_scheme_first → Y
autosuspend → 2
All without any success.
Here is the output of journalctl when I turn on the device:

Hopefully somebody could help me or give me a hint.
Any help is appreciated. Thank you
