Behringer UCM204HD shows only both lines (4 speakers)

[Udrys]

Hi,
I'm noob on linux so please don't beat me very hard :) I have Linux Mint 22 (Kernel 6.8.0-40-generic and Mint 21.3 had the same problem). So my UCM204HD shows only one 4 speaker channel. Not separate like on Windows or Debian. I tried to update configuration from this page but there are no difference. Maybe I'm missing something? Could you please help me? Thank you very much.

P.s. Apparently it's absolutely doesn't matter what I do with /usr/share/alsa files, they don't change anything.

I am sorry, but you may consult your issue with the community for your distro. If other distribution is working then it's does not look like a general issue.
