```
it seems that the card is not supported by ALSA lib.
How is the procedure to add new cards to the driver?
How can I help to do this?
Thank you

Hi,
some other Roland UA-* cards are supported:
- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/usb/quirks-table.h?id=14335d8b9e1a2bf006f9d969a103f9731cabb210#n510
- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/usb/quirks-table.h?id=14335d8b9e1a2bf006f9d969a103f9731cabb210#n1752
it is probably needed to add similar block of code for UA-4FX2.
You may also try whether an existing "quirk" would work with your card - through quirk_alias:
