SUMMARY
When clicking "Play" in the information panel to preview sound files in Dolphin, with bluetooth headphones paired, Dolphin plays with the built-in audio device instead of the bluetooth headphones.    

STEPS TO REPRODUCE
1. Pair bluetooth headphones
2. Select audio file (ex. mp3 file).  
3. In the Information panel, click on the triangle/play icon.  

OBSERVED RESULT
Sound is played with the built-in device instead of the bluetooth headphones.  It is also impossible to select "play audio using" bluetooth headphone in the mixer (systray) / Audio volume > Applications.  It is also impossible to select "play all audio via this device" [bluetooth headphones] in the mixer (systray) / Audio volume > Devices.

EXPECTED RESULT
When clicking on the play icon in the Information panel, the sound should play in my bluetooth headphones.
