That version number sounds like a RealTek version number. The latest version of the RealTek driver should be available via Windows Update and automatically installed. If no update is available there, then you have the latest version already.
If you are asking about the audio being delivered to your monitor/TV via DisplayPort or HDMI, then the necessary driver will be installed along with the graphics driver -- and this applies to driver packages for Intel HD Graphics, NVIDIA HD Graphics and AMD HD Graphics.
Hope this helps,
If you have a add-in (NVIDIA, AMD) graphics card installed, the Intel HD Graphics 4000 engine in your processor will typically be disabled. In this case, if you are connecting the TV/monitor to a DisplayPort or HDMI output from this add-in graphics card, you install the audio driver by installing the graphics driver for that card.
If you do not have an add-in graphics card, then the Intel HD Graphics 4000 engine in your processor will be your primary and you would be connecting the TV/monitor to a DisplayPort or HDMI output from this motherboard. In this case, if you install the Intel graphics driver package (download it from here: https://downloadcenter.intel.com/download/29473/Intel-Graphics-Driver-for-Windows-15-33-?product=814...), you will also be installing the audio driver..
