ALSA: hda/realtek - Remodified 3k pull low procedure
Browse files Browse the repository at this point in the history
[ Upstream commit 46cdff2 ]

Set spec->en_3kpull_low default to true.
Then fillback ALC236 and ALC257 to false.

Additional note: this addresses a regression caused by the previous
fix 69ea4c9 ("ALSA: hda/realtek - remove 3k pull low procedure").
The previous workaround was applied too widely without necessity,
which resulted in the pop noise at PM again.  This patch corrects the
condition and restores the old behavior for the devices that don't
suffer from the original problem.
