Audio output through bluetooth problem

Hello,

few day ago I bought my first Dell laptop (Inspiron 7720) and I can't make my bluetooth audiosystem (Logitech Mini Boombox) to work. I've got positive experience on Fujitsu-Siemens Amilo Xi2550 and on HP Compaq 6530b, where I had to just download another drivers for widdcomm bt adapter. I tried to do this trick o this computer, but I get only three bluetooth peripheral devices, which I can't install, because there is no driver for them. What shoud I do to make audio transfer through A2DP to work?

Thank you for your replies and pardon my english.
