From: Takashi Iwai Date: Fri, 28 Jul 2006 12:47:34 +0000 (+0200) Subject: [ALSA] Fix noisy output with shared channel mode with hd-audio X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4e195a7b78618c89b06547f3140e67a69ec23272;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [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.
