From 5b0cb1d850c26893b1468b3a519433a1b7a176be Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela <perex@perex.cz> Date: Tue, 8 Dec 2009 16:13:32 +0100 Subject: ALSA: hda - add more NID->Control mapping This set of changes add missing NID values to some static control elemenents. Also, it handles all "Capture Source" or "Input Source" controls.
