alsa-project/alsa-ucm-conf issue #489 was opened from rfvirgil:

Originally the configuration for sof-soundwire/cs42l43*.conf had the headset mic and internal mics on the same ALSA capture device 4. The Headset Mic enable and disable sequences ran as expected when the headset jack was inserted and removed.

But SOF expects that device 4 is the internal mics, and headset mic should be on device 1. So we made this change to move the headset mic to capture device 1: https://github.com/alsa-project/alsa-ucm-conf/commit/30989bd0c2aa3f9f4b6f5e3...

But now the Headset Mic enable and disable sequences do not run when the headset jack state changes. Seen on multiple systems with Pipewire + alsa-ucm + CS42L43 on sof-soundwire.

Example from a system that booted with jack unplugged. The jack was then plugged in. The CS42L43 has reported that the headset mic is present:

``` Simple mixer control 'Headset Mic',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] ```

But the enable sequence has not been applied (DP2TX1 and DP2TX2 should have been set to Decimator 1):
