From bac4b92cf7a444c0af8dd7b269c8791595c44052 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 4 Jul 2011 17:35:51 +0200 Subject: [PATCH] ALSA: hda - Don't add aa-mix for VIA surrounds Since we now route the front DAC via aa-mix widget, adding the aa-mix to surrounds will result in a mix-up of both front and surround PCM signals. For avoiding this, the aa-mix routes have to be disabled for surround paths.
