On a Dell laptop, there is no global adcs for all input devices, so the input devices use the different adc, as a result, dyn_adc_switch is set to true. In this situation, it is safe to control the micmute led according to user's choice of muting/unmuting the current input device, since only current input device path is active, while other input device paths are inactive and powered down.
