Windows 10: Help: IntelAudioService doesn't start and logs errors

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 ?)
