From 97a2657076f463ef06b6ef4ab6d54bb903ea9ff3 Mon Sep 17 00:00:00 2001 From: Kailang Yang Date: Fri, 29 Nov 2013 00:35:26 -0500 Subject: [PATCH] ALSA: hda/realtek - Remove depop delay for suspend and resume if applicable This patch defines a flag "no_depop_delay" in alc_spec. If this flag is set, delay in alc_eapd_shutup and alc_resume will be skipped. Machine-specific fixup can set this flag to reduce suspend/resume time, if the codec and hardware analog design can avoid pop noise without this delay.
