[firestorm override my music]

Hello,
i have a problem with the firestorm audio and my bluethoot headphones.
When I start the client if I have the voice enabled I can't hear other audio sources (for example spotify).
I have tried all kinds of possible settings but nothing to do, when I start firestorm the only audio I can hear is the one produced by second life.

Is there any way I can work around this problem?

P.S. use of Beats solo 3 bluethoot headphones

 

Thank you
