AudioPlaybackConnector2 is a small Windows tray app for connecting paired Bluetooth audio devices as Windows playback outputs. It uses the Windows AudioPlaybackConnection API so you can connect, disconnect, and reconnect A2DP devices without opening Windows Settings.

Built with WinUI 3 Desktop, C++/WinRT, and distributed as MSIX.

Quick Start

1. Pair your Bluetooth speaker, headset, or other A2DP audio device in Windows.
2. Download the latest .appinstaller and .cer from Releases.
3. Trust the .cer certificate once.
4. Open the .appinstaller file to install the app with its update feed.
5. Launch AudioPlaybackConnector2 and use the tray icon to manage devices.

For commands and certificate-store options, see Installation.

Features

• Tray-only workflow with no main window.
• Fast device picker on left-click.
• Connect, reconnect, and disconnect devices from the picker.
• Double-click the tray icon to toggle the most recently connected device.
• Disconnect or reconnect all active devices from the tray menu.
• Global and per-device auto-reconnect on startup.
• Guarded device actions so repeated clicks do not start overlapping connect/disconnect work.
• Animated, theme-aware tray icons for idle, connecting, connected, and error states.
• Toast notifications for connection events, failures, and available updates.
• Optional start with Windows.
• Manual update checks through GitHub Releases and the App Installer feed.
• Settings window placement persistence.
• Local crash reports and minidumps for troubleshooting.
• Localized UI in eight languages.

Requirements

• Windows 10 version 2004 or newer.
• A Bluetooth adapter with A2DP support.
• A paired Bluetooth audio playback device.
• MSIX installation through a release package or local build.

Usage

• Open device picker: Left-click the tray icon.
• Open tray menu: Right-click the tray icon.
• Quick toggle: Double-click the tray icon to connect or disconnect the last connected device.
• Settings: Open from the tray menu to configure language, startup behavior, reconnect behavior, notifications, and update checks.
• Command line: Use apc2ctl.exe from PowerShell, MacroPads, Stream Deck actions, or scripts:

apc2ctl status
apc2ctl list
apc2ctl connect --name "Device Name"
apc2ctl connect --mac "A1:B2:C3:D4:E5:F6"
apc2ctl disconnect --id "<Windows device id>"
apc2ctl toggle --last
apc2ctl reconnect-all

Add --json to status, list, or device actions for machine-readable output.

Installation Notes

The recommended install path is the .appinstaller file from the latest release. It preserves update-feed behavior and pulls in required framework packages such as VCLibs and the Windows App SDK runtime.

Direct .msix installation is still possible, but missing framework dependencies may need to be installed manually and update-feed behavior is not preserved.

Releases are currently signed with a self-signed certificate, so Windows must trust the release .cer before installation.
