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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539843 Title: Asus N551/N751: external microphone does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1539843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
