For those interested, I fixed the audio over bluetooth streaming issue (which indeed was caused by Beats audio & xloud) by removing the files from the beats audio cwm zip (0317 version) in the beats and audio thread:

and replacing the necessary files (because some files are updated by the beats and audio zip but are originally in the stock rom already) by copying them from the virtuous rom into wsg...
Now I can stream audio over bluetooth (well, until the wifi/bluetooth connection starts to crap)...
Not the easiest way but wanted to use WSG but also be able to stream audio over bluetooth
