It's not a big issue that's why I kept it close.

I just wonder if it's possible to poll HW and ask it "Hey, do you already have
firmware uploaded?" because it surely looks like Linux tries to upload it
without much success twice only to fail and realize it's not necessary.

I'm not sure btqca is affected by the same issue and it's not like too many
people casually switch between OSes all the time.

At the same time AFAIK ALSA has quite a number of workarounds to deal with the
exact same situation: Windows initializes audio HW a certain way and then it
starts malfunctioning after rebooting into Linux. It was the case years ago,
I've not heard much if any about this recently.

TBO, it more looks like the case of Windows not using cold reboot (and AFAIK by
default Linux doesn't do it either) but why would it if e.g. makes booting
slower.
