So, i've been having this problem ever since i got my monitor in February. I have a 23" LED 1080p Asus monitor (VS238H), and whenever i hook it up with hdmi to the monitor and try to get audio out of the 3.5mm jack on the monitor when playing PS3, it makes a static sound when i start a game. Audio works fine with my Xbox 360 and Macbook Pro, but for some reason won't go away with the PS3. I've tried headphones, iPod speakers, earbuds, different hdmi cord, nothing works! Please help. Thanks.
