Злостный светодиод [РЕШЕНО]

/*
* using power check for controlling mute led of HP notebooks
* check for mute state only on Speakers (nid = 0x10)
*
* For this feature CONFIG_SND_HDA_POWER_SAVE is needed, otherwise
* the LED is NOT working properly !
*
* Changed name to reflect that it now works for any designated
* model, not just HP HDX.

CONFIG_SND_HDA_POWER_SAVE = y
но светодиод все равно не меняет цвет
