I think it's a bug's AUDYA 4, I have the same problem, I turn on the AUDYA 4 and there's this problem, but if I charge a SINGLE REG. (anyone) the problem disappears.

And everybody think: Charge the SINGLE REG., and after save the CUSTOM STARUP, (if there's a information that set the AUDYA the next time you turn on the AUDYA will work well) but don't work.
