Re: Microphone detected, but no output for all ASUS G751xx with ALC668 chipset

[Håvard <hovardslill@gmail.com>]

Hi! Sorry for late response, was doing school stuff and had problems trying
to get nvidia drivers on 4.19-rc3 to work.

setting options snd-hda-intel model=alc668-headset
in /etc/modprobe.d/alsa.conf
on the 4.18.7-gentoo kernel it changed nothing (exept for the layout in
alsamixer - that is better).

I checked the source code in sound/pci/hda/patch_realtek.c and there seems
to be no difference between the code in 4.18.7 and 4.19-rc3

I could try testing more, but I am not good with sound tests without gui.
