BugLink: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4792 Cristian reported that these models have really bad sound above 6 dB and proposed the original patch. I've updated the comment to reflect this change. Signed-off-by: Daniel T Chen <crimsun@ubuntu.com> Reported-by: Cristian Klein Signed-off-by: Takashi Iwai <tiwai@suse.de>
