From cd896c331dd442c43cd9e23de3f1a4f3c111c292 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 18 Nov 2008 12:36:33 +0100 Subject: [PATCH] ALSA: hda - Allow multiple imux for matrix-type mixers of ALC codecs Allow the multiple imux instances for matrix-type mixers like ALC882. So far, only ALC260 used this feature, but other codecs may need a similar stuff.
