Neptune users who are using pulseaudio may have noticed a sound volume issue with event sounds that weren’t controllable with kmix. This was fixed with the latest updates that you can get from our Neptune KDE Repo. Eventsounds now use the default pulseaudio mixer. The volume can be controlled by playing back an event sound and either using kmix or pavucontrol to set the right volume.

A new big update is arriving for all Neptune 3.x users currently.
We provide a big update for packagekit and apper aswell as systemd 204 which brings a new udev version.
This Update brings usability improvements and stability improvements when it comes to the default software and upgrade center apper.

After the update you need to reboot.
Note: Apper might show an unknown error after successfully upgraded. You can dismiss this error message and reboot the computer.
