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

[Håvard <hovardslill@gmail.com>]

I am sorry for replying once again, but since we are already fixing this,
we might as well look into another one.

Many people are reporting that the headphone out port (wich is also an
SPDIF out port) is not working. I can get it working by overriding pin 0x16
to Headphone in hdajackretask, but this makes the internal speakers useless.

Reports online of this issue:

And, as mentioned in the last link, setting model=asus-mode5 seems to fix
that issue.


I know this is much to ask, but could you take a look at this as well? It
seems to affect a lot of people - I have been avoiding it by plugging my
headset in the line out port, but that should be a last resort option.
