Can audio be relayed through a USB connection, or does this drive need an audio cable connected from it to the computer? I ask because i have tried to play it on my computer but get no sound. I installed the software into my windows xp desktop i then put the DVD into the SuperSlim DVD writer and it played fine but i couldnt hear anything. I checked to see if maybe my speakers were the problem but they good. I played the DVD on my laptop and it worked fine. What can i check to fix this problem?
