The Question

SuperUser reader Dan Dascalescu wants to know what the Display Audio mentioned during his laptop’s driver installation process is:

I have downloaded an Intel HD Graphics driver for my Dell laptop and the installer’s welcome screen says it will install the following components:

• Intel Graphics Driver
• Intel Display Audio Driver

What exactly is Display Audio? Dell’s and Lenovo’s pages are spectacularly unhelpful.

The Answer

SuperUser contributors ultra sawblade and Techie007 have the answer for us. First up, ultra sawblade:

HDMI and DisplayPort are equipped for transmitting sound and in addition feature. To Windows, it would appear that an extra soundcard shows up in your framework, for which a driver is required. So on the off chance that you associate a screen on the flip side of your HDMI or DisplayPort and it can play sound, you can send sound to that screen by selecting "Intel Display Audio" or comparable as your sound gadget.

Followed by the answer from Techie007:

It is for sending sound through the feature connector (for utilization with feature interfaces that bolster it like HDMI and DisplayPort).
