optic probs
 

Hi there. Im new to this so sorry if im in the wrong bit. I have a splitter box which connects three items to my amp. sky, dvd and xbox. All three are patch leaded to a splitter box which then travels on one optic to my amp.
The wierd question is this...my sky box doesnt have sound to the amp? The only way I get it to work is to run the main optic lead into the sky box directly??
Ive tried using the different patch leads and tried different ports on the splitter, but nothing??
Can anyone PLEASE help...Thanks, steve
