From d590ee14c2952ac07e368430c8b985424c0641d5 Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng Date: Wed, 11 Mar 2020 14:13:28 +0800 Subject: [PATCH] ALSA: hda/realtek: Fix pop noise on ALC225 commit 3b36b13d5e69d6f51ff1c55d1b404a74646c9757 upstream. Commit 317d9313925c ("ALSA: hda/realtek - Set default power save node to 0") makes the ALC225 have pop noise on S3 resume and cold boot. So partially revert this commit for ALC225 to fix the regression.
