Hi,
I just downloaded to latest Image (02.2017) and updated it to 03.2017.
After this I installed BT Streaming and connected my iPhone 6s to stream music to OSMC
I can see BTPlayer is playing the music and I can control the music on my iPhone from osmc 
but I can’t hear the music. 
→ System sounds are hearable.
→ RPi3 is connected directly via HDMI
Thats my log: http://paste.osmc.io/wiwudawiwi
hope you can help me!
