From 8822702f6e4c8917c83ba79e0ebf2c8c218910d4 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Fri, 7 May 2021 10:44:52 +0800 Subject: [PATCH 01/10] ALSA: hda/realtek: reset eapd coeff to default value for alc287 Ubuntu users reported an audio bug on the Lenovo Yoga Slim 7 14IIL05, he installed dual OS (Windows + Linux), if he booted to the Linux from Windows, the Speaker can't work well, it has crackling noise, if he poweroff the machine first after Windows, the Speaker worked well. Before rebooting or shutdown from Windows, the Windows changes the codec eapd coeff value, but the BIOS doesn't re-initialize its value, when booting into the Linux from Windows, the eapd coeff value is not correct. To fix it, set the codec default value to that coeff register in the alsa driver.
