Cmedia had early success with its PCI multi-channel chip and later by successfully developing the PC motherboard AC’97 that evolves as an application of Intel High Definition Audio.

To fix this problem, use one of the following methods.Cmedia Electronics specializes in USB and PCI audio processing solutions for USB audio peripheral applications including headsets, handsets, microphones, speakers, sound stations, sound cards.įounded in 1991, Cmedia started as an audio chip designer. Because the new driver doesn't support the WaveRT port, the system can't access the driver. Therefore, the operating system assumes that the new driver also supports the WaveRT port. 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. However, both drivers use the 'wave' reference string when the device interface is registered. 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 doesn't.

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 can't be used, and the computer doesn't 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).

You connect a Universal Serial Bus (USB) audio device, such as an audio adapter or USB digital-to-analog converter (DAC), to a Windows computer for the first time.

This article discusses the 'Audio services not responding' error and USB audio device doesn't work in Windows 10 version 1703.
