VB-Cable Integration

[akonopcz]

Problem

• Users need VB-Cable for Discord sound routing but setup is manual and confusing
• VB-Cable installation changes Windows default audio devices unexpectedly
• No way for friends to hear both sounds AND the user's voice without complex configuration

Solution

• Detect VB-Cable devices automatically
• Provide one-click installation with automatic configuration
• Route microphone through VB-Cable so friends hear everything
• Document VB-Cable setup

Progress

• VB-Cable detection via cpal device enumeration
• Smart retry logic (5 attempts, 1s delay) after installation
• Save/restore ALL Windows default devices (prevents VB-Cable becoming system default)
• Silent VB-Cable installation (-i -h flags) with official CDN download
• Auto-configure as broadcast device after install
• Donationware notice (VB-Audio licensing requirement)
• Microphone routing to CABLE Input via cpal (so friends hear voice + sounds)
• Enable/Disable toggle for microphone routing
• Persist routing settings across app restarts
• Auto-enable mic routing on startup if previously enabled
• Setup guide documented
