SimAudioFixer

The definitive solution for audio device renumbering issues in iRacing and SimHub

---

Problem It Solves

Tired of iRacing and SimHub losing your audio settings every time Windows renumbers your devices? SimAudioFixer creates a stable fingerprint for each device and automatically updates configurations when GUIDs change.

Features

• Smart Detection: Identifies devices by hardware ID (VID/PID), not by temporary GUID
• Automatic Updates: Patches iRacing and SimHub configuration files
• Active Monitoring: Detects external file changes
• Notifications: Alerts you when reapplying is needed
• Dark Mode: Eye-friendly UI for night racing
• Auto Start: Runs silently with Windows (no UAC prompts)
• Automatic Backup: Restores configs if something goes wrong

Installation

Using the Installer (Recommended)

1. Download SimAudioFixer-Setup.msi from GitHub Releases
2. Run the installer as administrator
3. Launch from Start Menu or Desktop
4. Enable "Run at Windows startup" from tray menu

Silent Mode

SimAudioFixer.exe init

Supported Games

• iRacing (app.ini audio device remapping)
• SimHub (ShakeIT Bass Shaker output remapping)

Why This Exists

Windows randomly renumbers audio devices when drivers, USB ports or updates change. This breaks sim racing setups with multiple sound cards. SimAudioFixer makes device IDs stable forever.
