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.
Available in AUR: volctl
Install from source using Cargo:
cargo install --git https://github.com/buzz/volctl.git
Install the GSettings schema manually.
sh
cargo build --release
$PATH:sh
cp target/release/volctl ~/.local/bin/
Install the GSettings schema manually.
volctl uses GSettings to store preferences. The schema file must be installed for the settings to work. Copy the schema XML and compile the schemas:
PREFIX="${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
