I have tested the fix suggested in the comment #2, and verify that the fix works on Ubuntu Yakkety (tested with kernel 4.8.0-34). Steps to verify: 1. edit the hwdb (/lib/udev/hwdb.d/60-keyboard.hwdb) suggested as https://github.com/systemd/systemd/pull/5012 2. compile the hwdb by "sudo systemd-hwdb update" (or "sudo systemd-hwdb update --usr") 3. reboot 4. now the fn+f4 should work to mute the mic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654827 Title: Microphone mute Fn hotkey does not work on Dell Latitude 7370 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1654827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
