Fix OBS Studio Startup Crash Audio Driver

If OBS Studio crashes immediately upon launch, a corrupted or incompatible third-party audio driver or software is often the culprit. This guide provides a straightforward, step-by-step walkthrough to help you identify the problematic audio driver, disable or reinstall the conflicting software, and restore OBS Studio to full functionality.

Step 1: Identify the Crashing Driver via Crash Logs

To fix the issue, you first need to confirm which audio driver is causing the crash.

  1. Press Windows Key + R to open the Run dialog box.
  2. Type %appdata%\obs-studio\crashes and press Enter.
  3. Open the most recent crash log text file.
  4. Scroll down to the “Thread” section that mentions the crash, or look at the “Loaded Modules” list.
  5. Look for common problematic audio DLLs or drivers, such as:
    • Nahimic (NahimicMSIOps.dll or NAHIMICV3OSD.dll)
    • A-Volute / Sonic Studio (LgLgKeyHook64.dll or similar)
    • Realtek Audio (rtkaudservice.exe)
    • Virtual Audio Cable / Voicemeeter (vbaudio...)

Step 2: Disable or Uninstall the Problematic Audio Software

Once you have identified the software associated with the crashing DLL, you need to disable or remove it.

Option A: Disable Nahimic Services (Most Common)

Nahimic audio software, pre-installed on many MSI, ASUS, and Lenovo laptops, frequently conflicts with OBS. 1. Press Windows Key + R, type services.msc, and press Enter. 2. Scroll down to find Nahimic Service. 3. Right-click it and select Properties. 4. Change the Startup type to Disabled and click Stop if the service is running. 5. Click Apply and OK, then restart your computer.

Option B: Uninstall Conflicting Drivers

If the crash is caused by virtual audio drivers or companion software (like Voicemeeter or Sonic Studio): 1. Open the Windows Settings app and go to Apps > Installed apps. 2. Locate the offending audio software. 3. Click the three dots (or select it) and click Uninstall. 4. Restart your computer.

Step 3: Reinstall or Update Essential Audio Drivers

If the crash is caused by your primary audio interface (like Realtek, Focusrite, or Elgato Wave Link), the driver itself may be corrupted.

  1. Right-click the Windows Start button and select Device Manager.
  2. Expand the Sound, video and game controllers section.
  3. Right-click your primary audio device and select Uninstall device. (Check the box that says “Attempt to remove the driver for this device” if prompted).
  4. Restart your PC. Windows will automatically reinstall a clean, generic version of the driver.
  5. Alternatively, visit the manufacturer’s official website to download and install the latest stable driver version.

Step 4: Run OBS Studio in Safe Mode

If you have cleared the drivers but OBS still struggles to launch, try running it in Safe Mode to bypass third-party plugins that might be hooking into your audio system.

  1. Right-click your OBS Studio shortcut.
  2. Select Properties.
  3. In the Target field, add --safe-mode to the very end of the file path (ensure there is a space before the dashes).
  4. Click Apply and launch OBS.
