🔊 volctl

Per-application volume control and OSD for Linux desktops.

Screenshot

I couldn't find a simple tray icon that allows to control multiple applications easily from the task bar. So I wrote my own.

Bug reports and patches welcome!

It's not meant to be a replacement for a full-featured mixer application. If you're looking for that check out the excellent pavucontrol.

Control main volumes as well as individual applications
Mute individual applications
Shows application icons and names
Per-application VU meter
Click to open the mixer popup; right-click to open pavucontrol (or custom mixer application)

GSettings schema installation

volctl uses GSettings to store preferences. The schema file must be installed for the settings to work. Copy the schema XML and compile the schemas:

cargo run
