alsa-project/alsa-ucm-conf issue #349 was opened from raveit65:

First, i hope this is the right repository for the issue. I am using a 2.1 loudspeaker setup with fedora 38 and pipewire sound server. With alsamixer or qasmixer the subwoofer channel is swaped. With a 2.1 channel setup the subwoofer channel in qasmixer is silent. With a 5.1 channel setup the subwoofer channel is swapped with the back/right channel, and the subwoofer channel seems only mute/un-mute the subwoofer. But the volume itself is controlled by the back/right channel. I am thinking that the middle/front channel is also swapped with back/left channel, but not tested because i don't have an (active) middle/front speaker. It looks like a channel rooting issue but i don't have the knowledge about alsa to fix that with a asound.conf. The card is a usb-audio device. Beside from this issue the card works well under linux. I don't use the control box for headphones. I am happy to provide more information if requested. If you think this is alsa related i can close this kernel bug report. https://bugzilla.kernel.org/show_bug.cgi?id=217868 alsa-info: [alsa-info.txt](https://github.com/alsa-project/alsa-ucm-conf/files/12535277/alsa-info.txt)
