Big Picture Audio Switcher

Windows tray application for automatic switching between audio devices based on Steam Big Picture mode.

Build

There's an installer provided in releases (along with a zip of the binaries), but you can also build it yourself with the following commands:

cmake -DCMAKE_INSTALL_PREFIX=output_dir -S . -B build -G Ninja
cmake --build build --config Release
cmake --install build

Scripts

The application will run the scripts in the scripts folder. Specifically:

• onSwitchToNormalOutput.py - called when the application switches to the normal audio output
• onSwitchToTVOutput.py - called when the application switches to the TV audio output

These require Python 3 to be installed and accessible from the PATH.

Settings

In settings.ini next to the executable.

Items:

• normal - normal audio device
• tv - big picture audio device
• poll - polling interval in seconds
• show_balloons - show balloon notification on device change
• enable_log - enable logging to log.txt

In settings.ini in %APPDATA%\Roaming\BigPictureAudioSwitcher:

• startup_queried - set by the application, determines if the application asks about being started with Windows
