It's likely the issues with the implicit feedback.
The latest development tree (either linux-next tree or topic/usb-audio-refactoring branch of my sound.git tree) contains the improvements of the implicit feedback mode.

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 Playing WAVE './file.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:1407: Unable to install hw params:
It's a known side-effect of the implicit feedback mode, and the latest patchset I mentioned earlier addresses the issue.
