This 'audio not playing' problem occurs because the default USB audio 2.0 driver (usbaudio2.sys) uses the WaveRT port for operation but the device-specific driver does not. Both the Windows Audio and the Windows Audio End Point Builder services must be running for audio to work correctly.
When you select the icon, you receive the following message:Īudio services not responding. The speaker icon on the task bar is marked with an X mark. In this scenario, the device cannot be used, and the computer does not have sound. The downloaded device driver replaces the usbaudio2.sys driver.Windows then downloads the device-specific driver from Windows Update.The operating system detects the device and loads the standard USB audio 2.0 driver (usbaudio2.sys).
