From 068fd3a0811c0aace07ff9c3e1d17bbd1802f4b9 Mon Sep 17 00:00:00 2001 From: Kailang Yang Date: Fri, 27 Sep 2013 14:02:28 +0200 Subject: ALSA: hda - Fix Internal Mic boost can't control with ALC283 ALC283 pin control for Line1 default control by hidden register. Use line1 as internal Mic will not get sound when boost value up. Set control by verb for hidden register will solve this issue.
