Here is the cropped lsusb -v output:
I also have dmesg output with debug boot flag enabled.
Bus 001 Device 003: ID 0499:1509 Yamaha Corp. Steinberg UR22
OK, so it's a different device than UR22C.
Try to pass the module option quirk_alias=04991509:0499172f to
snd-usb-audio. This will make the device compatible with UR22C.

I removed snd_usb_audio and reloaded it with modprobe with the
parameters.
$ modprobe snd_usb_audio quirk_alias=04991509:0499172f
When I try to play a file now this happens:
$ aplay -D plughw:CARD=UR22 ./file.wav
