WOW there everybody, you missunderstood what I said.
Thru both the speakers, and headphones, the left & right sound constantly swaps over.
In the test mode, if I press the L button, the sound will come out the right hand speaker.
Press L again, and now it comes out the left hand speaker.
Press L yet again, and now it comes out of BOTH speakers.
This happens randomly of course, every time you press L it "randomly" chooses which speaker/headphone to play out of!!!!!!
It changes every time you press L or R, and is both with the speakers or headphones, so turning headphones around will not help!
Yes, I've tried 3 sets of headphones, and all are the same.
As others have said, its not a huge problem, specially when using the speakers, just annoying more than anything.
