So I just got a PS3, horrary! Anyway all I have at my disposal is my PC monitor, it has HDMI in so picture is not an issue, but what about sound? So far the best looking thing I can find is http://www.youtube.com/watch?v=65pB1Zefsh8&feature=related (and it has awful music) but it seems like this would be a major oversite, plus don't you just hook HDMI up to a TV and get sound fine? Why not a monitor?
If it's not working, could you just double check that:
1.) The *monitor* thinks that sound is coming through via HDMI (instead of through the 3.5mm jack)
2.) The PS3 is outputting sound through the HDMI cable (instead of, say, the optical output)
I think I just have to use the guide in that video, I already have the 2 male to 1 male connector. I just need the female female connector.
The HDMI connection should work for putting sound to the monitor's speakers. Have you tried connecting headphones to the monitor?
Also check your PS3's audio settings: http://manuals.playstation.net/document/en/ps3/current/settings/audiooutput.html
