Hi! I tried to set up the MANHATTAN "2800 Acoustic Series" Bluetooth Bookshelf Speaker System, via A2DP (+EDF) on Windows 7 Ultimate (x32 or x64, both available). The Speakers use Bluetooth 1.2 and the A2DP protocol according to the manual/specs, but there were no drivers included (nor available for download on manufacturer's website). I bought 2 Bluetooth USB sticks, both Bluetooth 2.0 compliant (each supporting A2DP & EDF, at least one of them definately Bluetooth 1.2 compatible), and tried installing various software to get A2DP sound output, including the software delivered with one of the USB sticks/dongles (seperately, combined, etc.). The programs I tried included BlueSoleil, Broadcom, Anycom, Toshiba, Windows Mobile Device Center, and others I found in numerous Google searches. After trying all those, I returned the speakers, but they were sent back with a note "use pairing function" (which obviously can't work if the speakers aren't recognized/found by any other bluetooth device) after supposedly being tested by the (online) retailer. Does anyone know how to get A2DP sound output working on Windows 7? I managed to find cell phones with the Bluetooth USB sticks/dongles, but the speakers were not detectable. I guess I must somehow set up the A2DP sound output option before finding the speakers, but I barely have any experience with Bluetooth. Thanks. Hi! The speakers only have an "on" and an "off" button, so there is no "discoverable mode". Obviously it's either a problem with the speakers or a Windows 7 issue (quite sure it's Win7, since a google search for ""Windows 7 A2DP" turn up thousands of forums full of people describing similar problems on Windows 7).
