Thanks for your report. Someone else complained too. I am currently
travelling, but I am currently trying to reproduce.
I will report  back when I have something useful to share.

In the meantime - you can try this firmware:

https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/log/?h=Core6

Of course, even if this one does work, we'll still make sure that your
current firmware will work with the current driver.

Thank you.
