Atheros Ar3012 A2DP Profile Problem

[mesay4]

I have Atheros Ar3012 which I found impossible to work A2DP bluetooth profile on it to pair with Logitech Bluetooth Adapter which only supports A2DP bluetooth profile. I have read related posts and tried each solution, unfortunately none worked. My ultimate goal is to use my Logitech Z906 sound system wirelessly with Logitech Bluetooth adapter; however, while my Sony Xperia Z mobile phone flowlessly works with Logitech Bluetooth adapter, whenever I tried to play music or video via laptop, things go wrong and I experience huge lagging, and stopped osund in every second. I am giving the details of Atheros Ar3012:

USB\VID_0489&PID_E036&REV_0001
USB\VID_0489&PID_E036

Thanks for support

Make sure you've got the latest Atheros drivers for your OS.
