Just wondering if anyone else has clicking/ticking and light squealing noises from the AA speakers when it's computer is processing? I find this most particularly occurs when I plug the AA back into it's power source after battery use. It produces these sounds for several minutes and eventually disappears.

Other times the AA can be completely away from potential interference and still when the AA computer is 'thinking', these sounds persist. Again, they eventually do go away.

Is this normal?

EDIT: I should add that these sounds do not always occur. For example (as noted above), when the AA is returned to a power source and the described sounds eventually go away, they often remain absent until the AA it is removed from the power supply and returned.
