Sounds similar to white noise, very loud. Happens only when playing hi res DVDs on the PWT.
It occurs when a new track is selected but only once in a while.
After the second time it happened on its own I was able to duplicate it.
With the volume set very low I played a hi res DVD and just hit the skip button over and over till it happened. I would estimate it occurred about 2% of the time.
What do we think is causing this?
