From: Takashi Iwai Date: Tue, 16 May 2017 07:11:33 +0000 (+0200) Subject: ALSA: hda - No loopback on ALC299 codec X-Git-Tag: v4.9.136~81 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ddf39e0f3cc2fada80d2795ca60777ec77fe6a7d;p=platform%2Fkernel%2Flinux-amlogic.git ALSA: hda - No loopback on ALC299 codec [ Upstream commit fa16b69f1299004b60b625f181143500a246e5cb ] ALC299 has no loopback mixer, but the driver still tries to add a beep control over the mixer NID which leads to the error at accessing it. This patch fixes it by properly declaring mixer_nid=0 for this codec.
