Comment # 2 on bug 1178203 from Takashi Iwai

... and scratch my previous comment, now I see the suggested commit showing the
implicit fb quirk for this device, which explains the situation.

It's a long-standing problem with those devices and we're still working on it,
but the fix is still not present yet.

As a quick workaround, you may try to pass a module option for the quirk
aliasing.  e.g. Create a modprobe conf file /etc/modprobe.d/60-UR22C.conf
containing the following line
  options snd-usb-audio quirk_alias=0499172f:04991111

which should prevent applying the quirk matching to 0499:172f.
