From 4e195a7b78618c89b06547f3140e67a69ec23272 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 28 Jul 2006 14:47:34 +0200 Subject: [ALSA] Fix noisy output with shared channel mode with hd-audio - Fix the wrong initialization of num_dacs when changing the channel mode between 2 and multi-channel modes. It must be evaluated after calling snd_hda_ch_mode_put() - Added the similar check of num_dacs fix in Realtek code.
