OutOfMemory Exception when running "The Dig"

[dellis1972]

I upgraded the WindowsGL project locally to use the latest version of MonoGame.
This involves using MonoGame's DynamicSoundEffect code.

When running the Dig I get a weird OutOfMemory Exception at the following location https://github.com/scemino/nscumm/blob/master/Engines/NScumm.Scumm/ScummEngine6.cs#L180

The call stack is as follows
