alsa-project/alsa-ucm-conf issue #385 was opened from Venkata-Prasad-Potturu: Hi, We have enabled ACP-DMIC endpoint support using SOF stack, and created mixer controls for capture switch and volume. Trying to link Mic mute button with amixer controls in the UCM config file, but unable to invoke the enable/disable sequence when we press mic mute button. Please find the below ucm configuration, amixer controls and pactl list.
