Asus N551/N751: external microphone does not work

[Alexandr]

Asus N551JM
In this laptop is combined jack for microphone and headphone. I use headset A4Tech Bloody G500 that nice work in Windows. But in KUBUNTU 15.10 and ubuntu 14.04/15.10 they do not work (work only as headphone). System don't see that i connected headset and in pavucontrol i see only embeded in laptop microphone.

Official support for Ubuntu 15.10 "Wily Werewolf" ended on July 28, 2016.

The fix for this issue will be in the 4.12 kernel. Ubuntu 17.10 "Artful Aardvark" is scheduled for release on 19th October 2017 and will be based on a 4.12 or later kernel. If you want to try the 4.12 kernel on Ubuntu 14.04 "Trusty Tahr", when the 4.12 kernel is released you can get it from the mainline kernel PPA page at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds
