alsa-project/alsa-ucm-conf pull request #837 was opened from lofiwatercat:
Got an SSL 2+ MK II and hit the UCM errors described in #795.
#681 added MK II support, but the author had no SSL 2+ MK II and could
not verify it. The merged regex (`USB31e9:000[29]`) therefore gives the SSL 2+ MK I the SSL 2+ MK II channel counts of 4 playback / 4 capture.
The SSL 2+ MK II actually has 6 playback and 8 capture channels, so the
config describes the device incorrectly and the card shows as
`[ALSA UCM error]`.
