Headset has a problem with surround sound

Hello,
Under Plasma there are the audio system settings, where you can make the sound settings. When I try to set the sound from Digital Stereo to Digital Surround 5.1 for my Rocca Elo7.1 air headset, nothing useful comes out of the test.

The headset is connected to the USB port via a sound card. I had the journal printed out for this purpose.

 journalctl -b -p err

Dmesg output the following for usb 1-7.2:

I searched online for the error message but couldn't find the solution.
What's wrong?
