alsa-project/alsa-lib issue #401 was opened from davidmcnabnz:

I just purchased a generic USB audio interface, which shows up in `lsusb` as: ``` 4c4a:4155 Jieli Technology USB Composite Device ``` The device on the whole seems to _simply just work_. But the level control for the stereo capture seems to be completely ignored, both in `alsamixer` and `pavucontrol`.

My setup is Debian GNU/Linux 12 (bookworm), standard apt including contrib. General stack is wireplumber and pipewire, implementing JACK via pw-jack and pipewire-pulse. This is working very well for my music work.

Lastly, below is a paste of my currently installed packages relevant to ALSA and JACK.

Grateful if anyone can advise.

Cheers David
