Area 51 M7700 with Windows 7 Bluetooth?

I am running Windows 7 Home Premium on this old laptop.
I purchased a Sony bluetooth headset and have used it on my wife's Samsung tablet and her Acer Chromebook. Headphones pair with both items and sound great.

I purchased a USB Bluetooth dongle for the M7700 and installed the dongle and it shows up in the device manager as operating correctly. The Bluetooth icon is in the taskbar.
When I attempt to pair the Sony headphones with the USB dongle it finds the headphones but says there is a driver missing. Windows goes online to find the missing driver but finds nothing.
I cannot get these headphones to work with this computer.
This M7700 was purchased by me, new, and I did not order Bluetooth at that time.

Any ideas what I can try to get these phones to work?

Thanks

 

Have you checked for the obvious like driver's on Sony's site? Also what dongle did you buy? There are new/old bluetooth revisiosns floating around out there. Perhaps, depending on what revision the headphones are using if the dongle was a cheap ebay part it may not support the headphones. For example I have a 2005 Dodge & a 2013 Subaru both with factory Bluetooth. Both work fine to make phone calls however only the Subaru supports playing of audio music over bluetooth. The 2005 dodge has an older bluetooth revision that does not support this most likely due to lower bluetooth bandwidth. Again these are just thoughts based on my own experience.

 

HI,

Thanks for writing back.
I did purchase a cheap Bluetooth dongle version 2 on ebay for .99
I'll pick up a better dongle and see what happens.
There were no drivers at the sony site for my model headset.

Thanks again
