问题

超级用户读者Dan Dascalescu想知道在他的笔记本电脑的驱动程序安装过程中提到的显示音频是什么：

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.

什么是显示音频？

答案

超级用户贡献者ultrasawblade和Techie007为我们提供了答案。首先，ultrasawblade：

HDMI and DisplayPort are capable of tran**itting 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.

然后是Techie007的答案：

It is for sending audio through the video adapter (for use with video interfaces that support it like HDMI and DisplayPort).
