From 62cbde1868b16e7cf1ed115cdfb9cbe82e230f0a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 14 Sep 2012 11:58:54 +0200 Subject: [PATCH] ALSA: hda - Add mic-mute LED control for HP laptop Some of new HP laptops have a LED for microphone (or recording) mute, and it's controlled by GPIO pin 3. Bind this with the capture switch to turn it on/off properly by the mixer change.
