Quality Windows Audio Video Experience

Services Most useful for those running Media Center, Quality Windows Audio Video Experience (qWave) is described by Microsoft as:
“qWave is a collection of QoS-related software modules that run on devices in the home network. qWave supports multiple A/V streams (real-time flows requiring QoS) and data streams (best-effort flows, such as e-mail) simultaneously over the home network, while providing a high-quality A/V user experience. qWave is targeted for home A/V scenarios and is disabled in other environments, such as an enterprise.”

Since it is set to start manually by default, it will only run when needed, so disabling it will offer little benefit.

  1. Some versions of the Creative Audo Products do not require this service to be running. For example the XF-i Series.
    any Creative sound card before this series of products in Windows Vista 64 Bit will requires this service. This is mainly as a base driver for the plug and play installtion of soem of the older legacy based audio adapters. This is however needed if you are going to be using an onboard audio adapter when it is capable of using High Definition Audio or known in the labeling/branding as a HDA.
