At first glance it looks like corruption. But it could be a fail-to-start error...

Are your audio services functioning correctly? Windows Server can often end up with disabled audio services.

Shove these into a batch file (in order) and run it with Admin privileges to check:

sc config MMCSS start= auto
sc config AudioEndpointBuilder start= auto
sc config AudioSrv start= auto
sc start AudioSrv

If it has to start any of them, components or dependencies of the Windows audio subsystem was disabled at a service level.

Also, try another codec - g722 or g729 - and see if that works OK.

Or maybe something in your program (perhaps the Opus DLL) is corrupt or you're trying to reference a library or framework you've not got installed?

I’ve developed a SIP softphone using liblinphone library.

It works as an automatic answer machine.

It accepts every call and records it.


I’m having some troubles running this app in a Windows Server 2012 R2 system.

It’s in a VMWare virtual environment (if it helps).


At the moment the app answers a call, and starts recording it, app crashes.

Looking at event viewer I can see an error with this info:


Exception code: 0xc000001d

Offset: 0x00027cdf

Faulting module: Opus.dll


Any idea what is happening here?

Many thanks in advance,
