[Jorge]

Hello I have an ASUS ROG-G752VM computer with Ubuntu 16.04 installed with and new kernel 4.12.0-041200-generic.

I'm having problems when I plug in the headphones and microphone, they don't work.

What I need to do?

From https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653456 comments #89 and #97:

To fix headphone jack, you need to use hdajackretask to override pin 0x16 to Headphone. This fixes the Headphone jack.

Please attach the output of alsa-info.sh.

[Kai-Heng Feng (kaihengfeng)]

Add "snd-hda-intel.mode=asus-mode1" your kernel parameter.

Chang the number "1" to 2~8 and see which works.

I confirm this bug also applies to Ubuntu 17.04 as well.

I haven't tested the microphone or SPDIF capabilities. But this is a workable pinout for most uses.
