+;
+; This is a generic chip used in multiple products, including at least
+; Behringer U-Phoria UMC22, Behringer Xenyx 302USB, Intopic Jazz-UB700 and
+; some unbranded "usb mini microphone".
+;
+; Behringer UMC22 has stereo input (representing two physical mono inputs),
+; others have mono input.
+;
+; Some devices have a mic input path, but at least Behringer Xenyx 302USB
+; doesn't have any input mixer controls.
+;
+; Since the UMC22 card has only stereo input PCM device but is commonly used
+; with mono mics, we define special mono mappings using "mono,aux1" and
+; "aux1,mono" channel maps. If we had only had the standard stereo input
+; mapping, the user would have to record stereo tracks with one channel silent,
+; which would be inconvenient.
+;
+; This config also removes default digital input/output mappings that do
+; not physically exist on cards that we've seen so far.
+;
+; Originally added by Nazar Mokrynskyi <nazar@mokrynskyi.com> for Behringer
+; UMC22.
