We can't confirm that your issue is with Debian until we fix this issue with apt, since it directly involves your kernel. Perhaps there is some underlying issue that it is getting at?
I appreciate your patience, the issues you are experiencing are very strange and frustrating. I am wondering why /boot/firmware doesn't exist on your system (it exists in mine), since you plan to install Debian 11 and upgrade to Debian 12 we will skip this mystery.
We are so close to release the installer should be very close to the final product, and many have already used it, the existence of raspi-firmware shouldn't outright brick your ability to upgrade your kernel, perhaps you did something strange with your partitions or how the disks are booting?
Anyways, I mainly want to see if you can get this system working on clean Debian 12 to see if the issues with the kernel have hopefully been fixed in a newer version.
Really narrowing down the issue at this point on stable likely involves some much more indepth technical debugging of your audio systems and the kernel which I think you would like to avoid :P. Sadly I think you have just some atrocious bad luck. Upgrading from 11 to 12 should be the safest upgrade path, remember to include non-free-firmware in your sources.list so that any non-free-firmware will be upgraded to the newer version aswell.
