Audio Hardware Connection: The Miles Sound System often fails to initialize if it detects no active audio output device, such as when speakers or headphones are unplugged.

Outdated Audio Drivers: Incompatible or old sound drivers can prevent the system from properly communicating with the game's audio engine.

Corrupted Game Files: Missing DLLs or corrupted installation files can break the initialization sequence.

System Permissions: Lack of administrative rights can block the .exe from accessing necessary audio components. Step-by-Step Solutions 1. Enable Stereo Mix

For many users on Windows 10 and 11, the game requires an active recording device to launch.

Right-click the Sound icon in your taskbar and select Sound Settings or More sound settings. Go to the Recording tab.

Right-click in an empty space and select Show Disabled Devices. If Stereo Mix appears, right-click it and select Enable. Restart the game. 2. Verify Audio Output Connections
