You should check the realtek website. All required drivers should be available there for your laptop audio device as well as any other realtek audio devices you may be using.
Typically the latest drivers are the best Realtek Drivers available. The driver in question would depend mostly on your hardware. Such as your soundcard and speakers. The latest version is currently R2.71 which is available since May.
RealTek's latest version is 2.63, but you should make sure that your motherboard manufacturer has not done some customizing to the Realtek hardware. The best place to get the latest version for your computer is the computer or motherboard manufacturer's website.

As of my last update, Realtek does not provide official drivers for the RTL8732BU WLAN-plus-Bluetooth 4.0 specifically for 64-bit Windows 7. Users often have to rely on generic drivers or third-party solutions, which may not guarantee full functionality. It's advisable to check Realtek's official website or forums for any updates or community-contributed drivers.
Use windows update, it will automatically locate missing drivers (sometimes it does not work).
