Hi, fresh install of Fedora41 workstation gnome edition.
The audio level is low out of my Behringer UMC404HD usb. Trying to load alsamixer to check levels I got this error for my usb card0
luca@fedora:~$ cat /proc/asound/cards
0 [U192k ]: USB-Audio - UMC404HD 192k
BEHRINGER UMC404HD 192k at usb-0000:00:14.0-4, high speed
1 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xf7f14000 irq 51
2 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7f10000 irq 52
luca@fedora:~$ alsamixer -c 0
cannot load mixer controls: No such file or directory
Alsamixer shows mixer controls for other cards (1 and 2), but crashes for card 0.
Weird thing is that everything works ok in the live usb before install, sound level ok and alsamixer works for card 0.
I had same issue with Manjaro, and moved to Fedora trying to solve it as this workstation is supposed to be a DAW, can’t have underperforming audio levels or lack of controls.
Couldn’t find any similar case, thanks as always for the Community Support. #fedora41#alsamixer#behringer
The live install is using an older Kernel. The newer kernel is still missing drivers. Have you checked on the Behringer Page if the device already has dirvers for 6.12 kernel?
Thanks, I have reinstalled the system from scratch.

The first boot after the fresh install works fine with kernel 6.11.4-301, same as the live install media. After system update and reboot anyway the kernel 6.11.4 generates same error with alsamixer. Anyway both 6.11.4 and 6.12.5 have now full sound level, though still no alsamixer.

Yes but unfortunately couldn’t find any support to linux kernel.
Prefer to stay with secure boot and fully supported kernel for some irrational reasons.
So, the correct sound level is back, the DAW is operative, unfortunately still no alsamixer so not confident it’s secure solution, but fine for now.
Thanks.
