Setup guide

Assign a dedicated key or dial to each output device.

Requirements

• Windows 10 / 11 (x64), .NET Framework 4.8
• macOS 13+ on Apple Silicon (arm64). Run Stream Deck natively; Rosetta and Intel Macs are excluded.
• Elgato Stream Deck software 7.1 or later
• Stream Deck+ for dial and touch controls. Keys also work on other Stream Deck devices.

Installation

1. Download and double-click the plugin package.
2. Install through the Stream Deck application.
3. Drag “AudioSwitcher+ → 音声出力 / Audio Output” onto a key or dial.
4. Select your output device. Use the refresh button to reload the device list.

Stream Deck+ required for dial and touch controls.

Add dedicated buttons

Drag Volume Up, Volume Down or Mute onto a key. They automatically target the current default output, so no device selection is required. Volume changes by 1% immediately, then by 1% every 0.5 seconds while held. Release to stop. Mute toggles once per press.

Audio Output action settings

• Output device: identifies a connected playback endpoint by ID. Reselect if its ID changes.
• Title: selecting a device sets its model name as the default title, e.g. Speakers (Soundcore 3) becomes Soundcore 3. Edit it using Stream Deck’s standard title field. There is no separate display-name setting.
• Volume step: 1–20% per tick, default 2%.
• Hold threshold: 300–2000ms, default 600ms. Hold and release a key or dial to toggle mute. Pressed rotation adjusts volume only; releasing it does not switch output or toggle mute.
• Communications default: Windows only: optionally switch the default output for calls. Mac switches regular audio output; system alerts and app-specific call routing are unchanged.

Behavior

Volume and mute apply to the assigned device regardless of the default output. Changing volume does not unmute. Status refreshes approximately every 1.5 seconds.

Activation means selecting the default output. Enable disabled devices in Windows first. Apps with fixed output routing or exclusive playback may need their own settings changed or a restart.

Mac device limitations

No additional tools are required. HDMI, DisplayPort and some USB DACs may not expose volume or mute controls to macOS. Output switching remains available. Unsupported operations are explained in the inspector.

Uninstall

Remove the actions and plugin in Stream Deck. Uninstalling does not restore the previous Windows output setting.
