K2: Audio stops until power is cycled

I have an intermittent problem. It rarely occurs, but since I mainly use  
the K2 for Contesting, it is a real annoyance. Suddenly all audio will go  
dead. The only remedy is to recylce power to the unit. It is very possible  
that this happens just after I make some control changes (like changing  
bands and/or filters).

I have also had one other strange occurance, that may or may not be  
related. The LEDs on the KAT-2 will all go dark, and stay that way. I  
believe the unit still tunes, but no SWR indicators on the panel at all.  
Again, the only fix is to recycle power to the unit.

Any ideas? I am guessing a communication problem, maybe AUX Bus related?

73,

Tom, KG3V
