[SOLVED] Do computer and GPU DisplayPorts contain the computer's audio (when converted to HDMI)?

[tomreedtoon]

I'm just beginning to work with DisplayPort equipped PC's - primarily the Dell Optiplex 9020 MiniTower. Its current GPU doesn't have HDMI (but a future one might). I know it has DisplayPort connections on the motherboard's built-in graphics. My question is this: do DisplayPort sockets carry the computer's audio, what you would normally have on the audio output jacks? And is that audio also present on the DisplayPort socket on a graphics card, without having to separately wire the audio inside the computer?

I ask because, if I was watching through the DisplayPort to an HDMI connector, I'd like to have that audio present. If it isn't, would I have to run a separate audio cable to the TV, or even worse, to a separate amp and speaker system, to hear the computer audio?

Or is there some kind of "breakout box" that would let you put the computer's audio down the HDMI cable - by cutting whatever was coming into the box and substituting your own audio?

Thanks for your help. I just want to understand what I would hear coming out of converted HDMI.

Inline audio from DP to Hdmi is supported via passive or active adapters. The need for a passive or active adapter will depend on resolution and refresh rate requirements for your TV.
