CopySound is a small utility for KDE Plasma desktops (Plasma 5 and Plasma 6) that provides audible notifications whenever the clipboard content changes.

On many Linux systems, there is no reliable system-wide notification when text or other data is copied to the clipboard. Users often repeatedly press Ctrl+C or Ctrl+Shift+C to ensure the content is copied. This utility solves that problem by providing a clear, audible confirmation using the standard KDE system sounds.

• Monitors the clipboard for changes in real time.
• Plays the standard KDE message notification sound (/usr/share/sounds/freedesktop/stereo/message-new-instant.oga) on clipboard updates.
• Compatible with both Plasma 5 and Plasma 6, requiring Qt6.
• Minimal, lightweight, and GPL-compliant.

• Qt6 development libraries (qt6-base-dev or equivalent)
• C++17 compiler (e.g., g++ or clang++)
• pw-play from pulseaudio-utils or pipewire for playing sounds

1. Clone or download the source code.
2. Create a build directory and navigate into it:

mkdir build
cd build

3. Build the program

cmake ../
make

4. Run it

chmod +x ./copysound
./copysound

5. (optional) Integrate it into your system by adding it

• into /usr/bin
• into session startup scripts
