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.
What is Display Audio?
SuperUser contributors ultrasawblade and Techie007 have the answer for us. First up, ultrasawblade:
HDMI and DisplayPort are capable of transmitting audio as well as video. To Windows, it looks like an additional soundcard appears on your system, for which a driver is needed. So if you connect a monitor on the other end of your HDMI or DisplayPort and it can play sound, you can send sound to that monitor by selecting “Intel Display Audio” or similar as your audio device.
Followed by the answer from Techie007:
It is for sending audio through the video adapter (for use with video interfaces that support it like HDMI and DisplayPort).
