Chromebook pro (caroline) and c302ca are two different variants of same google mainboard glados.
they used same codec nau88l25 but different Amp (ssm4567 or max98357)
is it possible to fix chromebook pro sound in a similar way?
I found some config file have different cset configuration,
what should I do to modify it for nau88l25max?
I compiled the kernel and replaced the firmware and configuration text from nau8825adi
cat /proc/asound/cards
displayed nau8825adi
but
pactl list cardsstill empty
Is a configuration problem?
thanks!
