Ahh, thanx EvilSOB! That solved my beep problem
Default beep was empty! I had it on windows default so kinda strange.
Now I can finaly test if my functions actually are called but I don't think it will solve the other music/wav playing problems.
EDIT: Suddenly got the wav working when copy and pasting from AUM 69 menu code, that changed the name from testwav = "mouseover.wav"; to mouseover_wav = "mouseover.wav";
What was wrong with testwav??
EDIT2: And what format should I use for the music files, since mp3 not suported? Need to find a converter...
