That's nothing related to any of our products, it's a plugin used by products like video editors from Adobe, Pinnacle, but maybe another FSX addon you have use it too.
We don't use that (I didn't even know what it was, before your message), fact that you are seeing this after installing GSX is purely coincidental.
GSX uses OpenAL for audio, but doesn't change anything in your system, all the files that it needs are included in its own folder.
