From 1c716153a87ae75c8bd63f1b6f7916300d87df7e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 7 Apr 2011 10:37:16 +0200 Subject: ALSA: hda - Introduce shutup callback to Realtek spec struct Add shutup callback to be called codec-specifically for avoiding pop noises at suspend or shutdown. As a generic callback, just turn EAPD off.
