Subject: ALSA: hda - Fix volume-init of ALC299 & co
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=050ea75317f33e376cc413359c0319ad5cc86e2a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda - Fix volume-init of ALC299 & co

ALC269 and compatible codecs have the output volume in DACs, thus we
can't use the ALC880's code as is.  Fixed by checking the amp caps and
picking up the right widget for initialization.
