Alright, so I'm working with a computer in one room, roughly 50ft away. I need to get USB, audio out/mic, and display to a monitor in a room over. What would you guys recommend?
Currently I'm toying with the option of a USB cable and then a displayport or hdmi run along with it. The less cables the better. One issue I've run into with audio over hdmi or displayport as there seems to be a complete lack of information about it. Video cards are supposed to be able to support audio over hdmi in the form of sound. They also supposedly support audio in over the auxiliary channel, but finding a video card that is compatible with that or lists it as a feature is a crapshoot. The same holds true for displayport.
Adding to the confusion is the fact that AMD video cards actually have a sound chip on board where as Nvidia cards supposedly act as a intermediary between whatever sound solution you have and the HDMI/DP cable. Yet, from what I've heard and read Nvidia cards are outright atrocious when it comes to this specific feature, it doesn't work a lot of the time and there are almost no features to tweak it with in the control panel (I don't have a Nvidia card so I can't confirm it).
As a AMD owner though I know there is a audio output listed in my sound devices, but there is no conforming audio input for the HDMI jack. Furthermore it's listed specifically as a HDMI audio device so I don't know if sound works over displayport. I don't know if this pertains to my specific video card, the model of video card, or even the series of video cards. I have a AMD 6970.
Really this is a huge crapshoot. I know audio over USB is an option, but I'd like to stay away from that as there is better use of remote USB bandwidth, I'd rather not to deal with the hassle of it, and purchasing a few USB audio devices can get expensive (this is for more then one computer). Running analog over another cable is a option too, but I could see that degrading over the runs, it would add another cable as well.
