How to config audio output to bluetooth instead of HDMI ?

[rafaeldeocosta]

I connected my rpi on my JBL speaker via bluetooth and it worked very well when I play a video in the rpi's browser. But when I try to cast videos using the raspberrycast, the sound goes out to HDMI instead of the bluetooth (JBL speaker).

When I connect the JBL speaker on the rpi via jack cable, the sound goes out to the JBL speaker when i cast video using the raspberrycast.

So, I figure out that could be a config option on the raspberrycast which I can choose the audio device where the sound must be played. Then, I looked up on the config file raspberrycast.conf but I didnt found such option.

Since, I cannot find any documentation about it, I decided to ask here.
