Hi 0thd,
I am suspecting that as well, here is the issue, the ST has a twisted notch to secure the cable to the ST jack in the player. If I don't secure it and yank the cable a little bit. I can heard sound!! I have other ST cables such as audio specific or data specific (for networking usage). My data cable will not work period. But the same cable will work on my Wadia 860 all the way plugged in and secured it. I will try to use duster gas to see if I get better results. Just hope I don't have a faulty ST jack, sending the unit back and forth to Wadia is pain the ass and not counting the days w/o music.....
