My laptop model is lg r480.Bluetooth is not working properly in windows 7. But working fine in linux. I installed the latest drivers also.

Make sure the Bluetooth drivers are properly installed on the computer, dont use the generic basic Bluetooth driver from windows.

Use the manufacturer Bluetooth drivers, cause it will resolve the Bluetooth connection issues between your computer and whatever the devices you are trying to connect to. Usually any small USB Bluetooth device will come with a small disc to install proper drivers or you can get it from the website of the manufacturer for the latest one.

Suggest you use Windows update to resolve this.

You need to install the Bluetooth driver and application, and later run the application.

Lenovo do not have Windows 8 bluetooth drivers on their support site.
You could try loading the WIndows 7 drivers (Broadcom Bluetooth Driver for Windows 7 32-bit or 64-bit)

Maybe there is no Windows 7 driver for it. That's one of the pitfalls of Windows 7.

Do a system restore and bring computer back in time before this was an issue.

Try to install the latest audio driver.
You can download the audio and device drivers for your model LG laptopor desktop from this WEB site.Make sure you select the correct drivers that match theversion of Windows that is installed on your laptop or desktop.
You can download the drivers from this site : -

When stepping up to a new operational system there are dangers where compatability will be an issue, I would go to the Samsung site under driver download to see if they offer a driver update for windows 7 for your model.

The drivers for Wndows 7 most likely will not work on Windows XP.
If this laptop came installed with Windows 7 it may not have Windows XP drivers.
Before you install Windows XP check the LG WEB site for Windows XP drivers for your model laptop. If there isn't any XP drivers then I suggest you stick with Windows 7.

try to uninstall the software, and installing it again in windows xp sp 3 compatibility, you can do so by right clicking on the installation exe of the drivers, select properieties, compatibility, windows xp sp3, check Run as administrator, OK. Install it now, and it could work now.

Hi, Please try downloading the latest soundcard driver from the sound card provider and it will fix the issue. I too did the same and now it works for me.
