DAPM PIN switches do not update in alsamixer when changed through UCM profile

Hi All,

I notice that DAPM PIN switches, such as e.g. the "Headphone" SOC_DAPM_PIN_SWITCH defined in: sound/soc/intel/boards/cht_bsw_nau8824.c:

static const struct snd_kcontrol_new cht_mc_controls[] = { SOC_DAPM_PIN_SWITCH("Headphone"), SOC_DAPM_PIN_SWITCH("Headset Mic"), SOC_DAPM_PIN_SWITCH("Int Mic"), SOC_DAPM_PIN_SWITCH("Ext Spk"), };

Do not get updated to reflect state-changes when the output is switched between e.g. Headphone / "Ext Spk" by pulseaudio/pipewire through the UCM profile mechanism.

If I exit alsa-mixer after changing the output and start it again then the control does show the expect value. So it seems that we are failing to send a change event about this somewhere?

Regards,

Hans
