I have not tried this before but it looks possible. Use this to do the pairing:

Having done this ensure that both the PP Track and the Show have the audio device set to 'blank'. PP should then play through the device selected in the Raspbian Task Bar.
It would be nice to add Bluetooth as a PP audio device. Do contact me via pipresents.wordpress.com and tell me how you get on. I don't see everything on the Forum.
