I have a LG G2 with stock Android 4.2.2. (build number JDQ39B)

Spotify is version 0.7.4.606.gd2ce8b10

The bluetooth "server" is latest version of software in a BMW 3-series 2013 model (aka F31) (TN-1.37.1 and MN-1.36.2)

When I connect with bluetooth from the phone I am able to start beyondpod and wimp, but not spotify. I can switch between beyondpod and wimp, and they work flawlessly (the app I switch to start playing, and the other one pauses), but when I switch to spotify the player starts to play, but no sound is coming out of my car speakers.

This seems to be a bug in Spotify. Please help.

btw: I tried using Media Button Router, but no help there.

Thanks in advance
