ALC1220 Broken Front Panel

[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #123 was opened from vs49688:

Since upgrading from v1.2.4 -> v1.2.5.1, I can no longer get any input/output from my front-panel.

I've bisected the issue to 5947daef124c84fae511233248196576dfbfab7c. Reverting fixes it, but this may break other cards.

The hardware is an "AX370-Gaming K7", with a ALC1220 chip.
