This is just weird. Yesterday I connected my new bit torrent computer to my Pioneer Elite VSX54TX receiver via the optical output on the Turtle Beach Sound Card. Everything played fine except the rear channels. When I went into the Turtle Beach software to try to get the rear channels working I lost the front left audio entirely! Here's where it gets really strange. I disconnected the optical cable from the Elite receiver and had no left channel from any audio source. But wait, it gets better. I unplugged the receiver and left it unplugged for about 3 hours. When I plugged it back in I had the left channel for about 10 minutes before it died. I have reset the receiver and left it unplugged for 24 hours and just checked it, plays for 10 minutes, left channel dies. I have swapped right and left outputs and it is most definitely a problem in the left preamp output. The optical cable has been unplugged since this started. What happened?
