I've compiled a kernel from 
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
uname -a is "Linux meschi-Precision-WorkStation-T5500 
5.10.0-rc7-next-20201208 #1 SMP PREEMPT Tue Dec 8 12:28:39 CET 2020 
x86_64 x86_64 x86_64 GNU/Linux"
The problem is still there. Is it possible to fallback to explicit 
feedback mode for the device from user space?
I'd like to learn more about these feedback modes, is there a place 
where this is explained?
I'm curious how this device is working on another machine. I'm not quite 
proficient with the alsa kernel subsystem to debug this myself,
but I would be happy to test patches and learn along the way if somebody 
is interested in debugging this.
