I.e. is there an audio driver for it? If it is, look at the audio-micmute LED trigger. If you can't use the audio-micmute trigger because the microphone isn't supported via Linux, I still think the LED should the LED should be read-write. You can then register a LED private trigger. The driver should change the state of the LED according to the microphone mute state only if these trigger is enabled. Marek
