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: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (125011 125012) PERIOD_SIZE: 5513 PERIOD_BYTES: 22052 PERIODS: (3 4) BUFFER_TIME: 500000 BUFFER_SIZE: 22050 BUFFER_BYTES: 88200 TICK_TIME: 0
