Hi SlackJaw,
Sorry for the late reply. I had some shows which kept me busy. And sorry for my unknowing, I am a complete beginner in this area.
I was looking a bit more and found this thread:
This explains the issues i have and managed to fix them. Just that the volume increases a lot but that’s not such a big issues for now 
I have some more questions relating the OneLibrary system. Should i open a new thread? I did find some info but it’s dated and sometimes confusing.
Thanks for your time!
