From de3da4f696b473e7810bd9837c18bf9fd30a9a6d Mon Sep 17 00:00:00 2001 From: Gabriele Mazzotta Date: Fri, 8 Aug 2014 19:34:41 +0200 Subject: [PATCH] ALSA: hda - Fix pop noises on reboot for Dell XPS 13 9333 If nid 0x15 (Headphone Playback Switch) is in D3 and headphones are plugged in when the laptop reboots, a pop noise is generated. Prevent this by keeping nid 0x15 in D0 when headphones are plugged in.
