I use my computer monitor to play my ps3 on and lately i cant get my sound to work. i have my picture working and i bought one of those converters that you plug the red and white cord things into and then i have that plugged into my Line In socket on my computer and im pretty sure i did that before and the sound worked great but now im getting nothing. i went to the sound settings on my ps3 and put it to Audio Input Connector/SCART/AV Multi and yea...nothing. im completely stumped as to what i need to do now
