• Method 3 – Restart & Disconnect USB Devices. The next thing you can try is to disconnect all USB devices and then restart the machine. Once you have restarted, try to connect the USB device that was causing the problem. If that particular USB port doesn’t recognize it, try another one.
• Short description. This driver/program is intended to 'overclock' USB mice (and other devices) under Windows 98, 98SE, ME, 2000, XP, Vista, 7, 8, 8.1, 10 including x64 versions. Also may be used for downclocking (and downclocking shall work always).

Symptoms

Consider the following scenario:

1. You connect a Universal Serial Bus (USB) audio device, such as an audio adapter or USB digital-to-analog converter (DAC), to a Windows 10 Version 1703-based computer for the first time.
2. The operating system detects the device and loads the standard USB audio 2.0 driver (usbaudio2.sys).
3. Windows then downloads the device-specific driver from Windows Update.
4. The downloaded device driver replaces the usbaudio2.sys driver.

In this scenario, the device cannot be used, and the computer does not have sound. The speaker icon on the task bar is marked with an X mark. When you select the icon, you receive the following message:

Audio services not responding. Both the Windows Audio and the Windows Audio End Point Builder services must be running for audio to work correctly.

Cause

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. However, both drivers use the 'wave' reference string when the device interface is registered.When the device-specific driver replaces the default driver, the device interface that is created by usbaudio2.sys is still used because the reference strings overlap. Therefore, the operating system assumes that the new driver also supports the WaveRT port. Because the new driver does not support the WaveRT port, the system cannot access the driver.

Resolution

To fix this problem, use one of the following methods.

Method 1

Uninstall the device. To do this, follow these steps:

1. Open Device Manager.
2. Select and hold (or double-click) the name of the device, and then select Uninstall.

Note:In step 2, don't select the Delete the driver software for this device check box.

Method 2

Connect the device to a different USB port. The problem may not occur if the device is connected to a different USB port.

Method 3

If the device is not yet connected, install the device-specific driver first. You can do this by using the appropriate installer for the device. Then, connect the device. Windows now selects the device-specific driver instead of the default USB audio 2.0 driver. This method works in this situation because the problem occurs only if the device-specific driver replaces the default driver after the device is connected.

Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as keyboards, mice, joysticks, printers, scanners, storage devices, modems, and video conferencing cameras. Migration to USB is recommended for all peripheral devices that use legacy ports such as PS/2, serial, and parallel ports.
