Multi Audio

A DankMaterialShell plugin that combines multiple audio output devices into a single virtual sink, so you can play sound through several headsets at once.

Built on top of PulseAudio/PipeWire's module-combine-sink via pactl.

• Control Center widget listing all available audio outputs with friendly device names
• Select two or more outputs and create a combined virtual sink in one click
• Newly created combined output is automatically set as the default sink
• View and remove active combined outputs at any time
• Bar pill indicator showing the number of active combined outputs
• Settings page with the same controls plus a configurable name prefix for created sinks
• Auto-refreshes device state, so hotplugged devices show up on their own

• DankMaterialShell >= 1.5.0
• pactl (provided by pulseaudio-utils or PipeWire's pipewire-pulse)

1. Open the Control Center and expand the Multi Audio widget
2. Tick two or more devices under Available Outputs
3. Click Create Combined Output — a new virtual sink (e.g. multi_output_1) is created and set as the default output
4. To dissolve a combined output, click the delete icon next to it under Active Combined Outputs

The name prefix for created sinks (multi by default) can be changed in the plugin settings.

Creating a combined output runs:

pactl load-module module-combine-sink sink_name=<prefix>_output_<n> sinks=<sink1>,<sink2>,...
pactl set-default-sink <prefix>_output_<n>

Removing one simply unloads the corresponding module. Devices that are already part of a combined sink are hidden from the selection list to avoid nesting.

Combined sinks created this way do not persist across audio-server restarts.
