Diagnostic s/w for spdif

[Dirk Bruere at NeoPax]

I have a problem on an AV system.
I want to use a prog of my own on the system that uses the spdif.
However something is holding the spdif and I cannot access it.
Does anyone know of any diagnostic s/w that will tell me exactly what
prog or service is tying up the spdif, or alternatively is there any way
of freeing it?

I'd guess you have it set as the default audio out. I forget
the exact term for this - WAVE MAPPER or whatever...

If not, uninstall and reinstall the device. If you can do what you need
done with it uninstalled...

By 'holding', what exactly do you mean? Are you getting some sort of
permission error, or resource in use error when you run your s/w? And now
for the big question: What sort of O/S is the AV equipment running? It
could be anything from a custom RTOS to Linux. And how an I/O port or
resource is 'held' depends a lot on this.

Yes - sorry.
It's Win7 embedded.
I am trying to use VST and output over spdif, however something seems to
be using it already. There's a big mix of AV s/w that might be
interfering and I am not in a position to uninstall all of it.

All the right boxes in the OS and apps seem to be ticked but something
is obviously not right.
