Well I have this lcd but does not have hdmi in it so i was out and found some $7 hdmi to dvi cables from an automotive/tool store, any way when i try to get the sound from av cables it will only work if im on the av setting or ybpcr or somthing like that setting anyone else have this problem and fixed it because i dont feel like getting opitical speakers. by the way this is for my ps3.
