Help: IntelAudioService doesn't start and logs errors

Anonymous

On a almost pristine Win10 installation as provided by my reputable laptop manufacturer ('almost' = pristine + a few updates: Windows, manufacturer drivers, a couple of personalization things), I have the IntelAudioService that can't be started.

This service is set to automatic, but the System log reveals regular 'critical' events (Service Control Manager: 'The Intel(R) Audio Service service terminated unexpectedly.  It has done this 1 time(s).') (manual start attempts result in 'Error 1067: the process terminated unexpectedly').

At the same time, the Application log reveals two consecutive events:

The second being an 'Application Error' in 'IntelAudioService.exe, version 1.0.748.0', Faulting Module 'ControlModule.dll'

and the first containing perhaps hints on the source cause (see below):

The laptop Support engineers are not too keen to help me out (fingerpointing), so if anyone here could hint me .....It could be interesting to know is this service is part of the generic Windows10, or if it gets installed with some audio drivers or other OEM software ? Interestingly, there are no apparent malfunctions with the system (so I wonder what the IntelAudioService is supposed to do ?)

    Method1:

    • Remote Procedure Call (RPC)

    Running OK

    • Multimedia Class Scheduler

    No such service found on any of my Windows computers

    • Windows Audio Endpoint Builder

    Running OK

    Method2:

    I've been through most of this already; as explained this is a scratch reinstall.

    Method3:

    Is already OK

    To confirm that my current workaround (set the startup to Manual-> do not run the service) is harmless, please try to find out:

    • is IntelAudioService part of the generic Windows10 installation (or is it an OEM or third-party driver component) ?
    • [if the former is true] what is the purpose of this service ?

    This would help a lot before deciding if I should spend more expensive time troubleshooting the issue

    Hi,

    Thank you for writing to Microsoft Community Forums.

    This can be if the service is corrupted or the corresponding services are not working. Here are few methods you can try:

    Method 1: Check if the corresponding audio services are also working.

    1. Open Run (Windows key + R) and then type: services.msc.
    2. Now check if the following services are running.
    • Remote Procedure Call (RPC)
    • Multimedia Class Scheduler
    • Windows Audio Endpoint Builder
    1. If the services are not running, right click on them to start them.

    Method 2: Uninstall the drivers.

    1. Open Device manager (right click on Start button and then click on device manager).
    2. Then expand Sound and Audio drivers. Uninstall all the drivers by right clicking on them (one by one).
    3. Restart your computer. This will restore the drivers to default.

    Method 3: Modify Registry key

    1. Open Run (Windows key + R) and then type: regedit. This will open Registry editor.
    2. Navigate to location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioEndPointBuilder\Parameters
    3. Locate ServicDll and if the value is %SystemRoot%\System32\Audiosrv.dll, this is the cause of the problem.
    4. Replace the above value with this: %SystemRoot%\System32\AudioEndPointBuilder.dll
    5. Restart your PC and check.

    Disclaimer: The registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles of each of the user accounts on the computer. Windows often reads and updates the information in the registry. Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry. Changing registry files incorrectly can cause Windows to stop working or make Windows report the wrong information.

    Please take a backup of the registry. Here is an article to help you: How to back up and restore the registry in Windows

    If the above doesn’t work, then you will need to replace the registry from a different computer with the same architecture (32 bit or 64 bit) running Windows 10.

    1. Open Run (Windows key + R) and then type: regedit. This will open Registry editor. Note: You will need to open this on a system where this service is running and which is on Windows 10 with the same architecture (32 bit or 64 bit).
    2. Go to HKLM/system/current controlset/services/audiosrv click on audiosrv and then on the file menu select export and save the file on a USB drive or disc. Then copy that on your machine and merge it. To merge it, please double click on the registry file. Then restart your system.

    Happy New Year. Have a great year ahead!
