Per-application volume control and OSD for Linux desktops.

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.

• Runs on virtually every desktop environment (via SNI)
• 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)
• Mouse-wheel support
• On-screen volume display (OSD)
• Supports X11 and Wayland

Available in AUR: volctl or volctl-bin

Install from source using Cargo:

cargo install --git https://github.com/buzz/volctl.git

Install the GSettings schema manually.

1. Clone this repository and build in release mode:

   cargo build --release

2. Copy the binary to a location in your $PATH:

   cp target/release/volctl ~/.local/bin/

Install the GSettings schema manually.

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:

PREFIX="${HOME}/.local"
mkdir -p "$PREFIX/share/glib-2.0/schemas/"
curl -fsSL https://raw.githubusercontent.com/buzz/volctl/main/data/apps.volctl.gschema.xml \
  -o "$PREFIX/share/glib-2.0/schemas/apps.volctl.gschema.xml"
glib-compile-schemas "$PREFIX/share/glib-2.0/schemas/"

cargo run

cargo clippy
cargo fmt

This is a Rust rewrite of the original Python version. The Python implementation is still available on the legacy-python branch.
