There are a few bugs in the AN1x that only surface after a long
period. I've noticed that the right channel goes off, crackling,
after the unit has been turned on for some time.

At one point, my AN1x became virtually unusable. I had to reset
it to factory defaults, which solved the problem. So, if all else
fails, save your patches and reset the AN1x.
