Public bug reported: [ Impact ]
* New Intel WCL platform with CS42L43B codec will find dummy input audio device [ Test Plan ] * Install the updated alsa-ucm-conf * Remove the existing alsa state in /var/lib/alsa/asound.state * Reboot the system by $ sudo echo b > /proc/sysrq-trigger * Verify the audio function after reboot on machine with CS42L43 and CS42L43B machine - built-in input/output should work - plug headset input/output should work - All function should keep working after suspend/resume [ Where problems could occur ] * To enable CS42L43B, it modifies the setting of CS42L43B as well, which might breaks CS42L43B's function.
