alsa-project/alsa-ucm-conf issue #437 was opened from Gess79:

I hope I'm correct to post this here. Still new to things Linux.

**Situation** OS: Kubuntu 24.04 Mainboard = ASUS ROG Maximus Z790 Hero USB Audio = 0b05:1a53 ASUSTek Computer, Inc. USB Audio Speakers = Logitech Z906 Surround Kernel = 6.8.0-40-generic Alsa version = 1.2.9

**Issue** The speakers seem to be assigned incorrectly and the subwoofer isn't working. I'm testing the speakers through pulseaudio as follows:


I'm listing the results below in three categories: - The icon clicked within pulseaudio - The soundfile played - The speaker the sound is actually output to

_Icon clicked - Soundfile played - Physical speaker output_ Front Left - Front Left - Front Left Front Center - Front Center - Rear Left Front Right - Front Right - Front Right Rear Left - Rear Left - Front Center Subwoofer - Rear Center - Rear Right Rear Right - (nothing) - (nothing)

I've had a lengthy discussion on Reddit but I couldn't find a fix for it so far: https://www.reddit.com/r/linux4noobs/comments/1980uv1/comment/kieqsor/

I'm happy to provide all information necessary to pinpoint the issue and fix it.
