Verification failed. It seems we need to fix this problem not only in notify-osd-icons but also in unity-settings-daemon.
The steps I performed verification as below: I Installed 14.04.3 LTS to a lenovo laptop enabled -trusty-proposed source from Software&Updates run Software Updater to update all packges run dpkg --list to check notify-osd-icons, this package is not updated download the this package from https://launchpad.net/ubuntu/trusty/amd64/notify-osd-icons/0.8+14.04.20151016-0ubuntu1 manually install it run dpkg --list to verify this package is installed reboot test microphone mute, the osd icon is still speaker rather than microphone. So it looks like we need to upgrade the unity-setting-daemons for trusty as well. ** Tags removed: verification-needed ** Tags added: verification-failed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1381856 Title: [Dell Latitude E5550] Microphone mute key does not work on this system To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1381856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
