@heinzelrumpel: the only problems I had with Bluetooth (same as yours: disconnect sometimes while playing) was, when the powersupply was not giving enough power. If you have some kind of powered USB-Hub, you could try to connect the Bluetooth stick there and see if this solves your problem. What else do you have connected to your Pi? You may also (just for testing) remove everything but the Bluetooth dongle, to see if the power is a problem.
