Mixer settings faulty on M-Audio C400 (usb) after suspend until they're touched in alsamixer

I don't know if this is the right place to report it, but:
I do a suspend and resume on my machine
Now, my mixer settings for my M-Audio C400 usb-soundcard are set to output all signals on the first pcm out
alsamixer doesn't reflect the true settings of the mixer, instead it shows the last used (correct, or wanted) settings
Once i touch one of the mixer controls in alsamixer, the settings get set to the correct values (+ that change i did)
This repeats every suspend/resume-cycle
I've observed this on Debian Bullseye and now on NixOS 23.05.
Thanks in advance, even if you point me to a better place to post this.
I can supply more debug info, once i know what you need, but the upload from alsa-info to www.alsa-project.org failed somehow without providing me a url. So, here's some basics:
