We are able to manually toggle the mic mute LED status by following commands echo 1 | sudo tee /sys/class/leds/platform::micmute/brightness - Mic Mute LED turns on echo 0 | sudo tee /sys/class/leds/platform::micmute/brightness - Mic Mute LED turns off It seems mic mute LED trigger event is not functional as expected. For the legacy stack(No DSP enabled) Soundwire + PDM IO combination, since the ACP PDM Mic Mute control is linked with the HDA UCM, As per our understanding LED event trigger needs to be checked from HDA UCM perspective. @perexg could you please share your inputs. @mrhpearson please add if we miss any relevant information.
