Hi guys, I have a problem with the line in jack (I think). When I connect my MD player to the rear Line In (Line In 1 in Surround Mixer), I can hear its sound from the speakers, but can't hear it through the headphones, which I connect to the headphones input on the Live!Drive IR. I tried reinstalling Drivers but it didn't help. Still, can't hear my MDs through the headphones. Please help me .
