Hi, Johan, thank you for looking into this. I tested your patch, and it
works! (5.4.11 and 5.5.0).

I haven't performed extensive tests, but the card is again recognized as
both playback and capture device. Thank you!

Is this and acceptable solution and will this patch be integrated into the
kernel?

OTOH, you said:

I can't say I understand exactly what you're saying, but do you think it
could be worth contacting the company and see if they are willing to fix
this with a new firmware?

Anyway, it's working now, thank you again.
