Some volume controls are swapped #410

When using amixer and alsamixer, I noticed that the volume controls for certain channels are reversed. I have verified the problem with two sound cards:

Terratec Aureon XFire8.0HD
hifidom DSC8-MAIN

Both are USB sound cards (UAC2).

Both sound cards have the channel map: FL FR FC LFE RL RR SL SR (cat stream0)

The channels FC/LFE are swapped with RL/RR.

I am using Ubuntu 24.04. The version of libasound2t64 is 1.2.11-1build2.

I am happy to help with troubleshooting.

Could you show me output for amixer -c 0 contents (replace zero with the affected card number) when the device is in use? Thanks.
