Back in the summer of '03 this was a problem which was solved through a 
tweak in the KDSP2 code and in some cases a component change to the K2. 
  It occurred with K2s below serial number 3000, and mostly when they 
were using an external KAT100 as I recall.

What is the serial number of your K2, its firmware version, and the DSP 
firmware version?  Do you have an external KPA100 and/or a KAT100 
attached when this symptom is observable?
