Spotify has a problem with stand-by and Bluetooth on Mac OS X. When I open my Macbook Pro and it comes out of stand-by it automatically reconnects to my Bluetooth-speaker. When the Spotify-app is still open and I hit play I see the song playing (the seconds count up), but I don't hear any music.
I have to shutdown the Spotify-app and restart it, only then when I hit play I will also hear music.
I have tried this on multiple Macbooks and reinstalled Spotify several times. It really looks like a Spotify software issue in de Mac OS X-version.
