Hello,
I don't think this is likely to help your issue, but if you haven't
already, you should try booting linux with the option iommu=soft
That was necessary for an issue I had with another card that uses the
snd-emu10k1 driver.
Sorry if it doesn't help.

If the card is recognised well the card works out of the box, but in
half of all boots the card is not recognised. For some reasons the card
didn't get an interrupt and then the card is not available in
/proc/asound/cards
working state:

In the not working state the cards get no interrupt, but the interrupt
above ( 18) in not given to another card or something

Board is an Asus PRIME Z270-K with bios 1207.
I have tested the card in another pci port and also have changed the
card to a new one, both without success.
Can you please help me to debug this further? When you need additional
information, please ask and I will provide it.
