audiosrv.dll - What is audiosrv.dll?


audiosrv.dll File Description:

Audio functions in Windows are executed by the module audiosrv.dll. This module together with the DLL winmm.dll controls sound capability.

In initializing the Windows Audio Controller, the DLL audiosrv.dll implements functions based on Remote Procedure Call services. The Windows Audio service can run on one or multiple RPC services that are available on the following endpoints: the AudioSrv LPC port and the AudioSrv named pipe (Windows XP before Service Pack 2).

In Windows XP, the audiosrv.dll file is essential in the seamless operation of applications linked with the file winmm.dll. If the audiosrv service is not present in the system, the setupapi.dll file will interrupt the application's execution, which will slow down or hang up the system. The application PlaySound relies on the audiosrv.dll file and the winmm.dll file. It does not need the setupapi.dll file until it actually starts playing sounds, which is rarely called by the user.

At the same time, the audiosrv.dll file monitors for plug and play notifications. This provides the application lead time to respond to plug-and-play changes without having to burn a thread and a window pump. Whenever a user plugs in their USB speakers, the audiosrv.dll file automatically detects it and notifies the appropriate application.

The audiosrv.dll file is also called to manage audio preferences and audio effects. Its management functions even extend to global audio digital signal processing. But probably the most important or widely acclaimed function of the audiosrv.dll file is its ability to offload PnP (plug-and-play) functionality. In lower versions of Windows, this functionality was actually a part of the Windows client/server runtime subsystem, but in Windows XP it was broken out into its own service to ensure better performance.

For the audiosrv.dll module to do its job, the following functions need to be loaded in Windows Audio:

* Multimedia Class Scheduler

* Remote Procedure Call (RPC)

* DCOM Server Process Launcher

* Windows Audio Endpoint Builder

* Plug and Play
