PATC sound and MCE?

Hi,

I have MCE's copilot responding very accurately, but I've now resolved a sound problem with my networked PATC, and the voices of PATC's controllers and ATC chatter are causing my copilot to complain, and sometimes carry out procedures I haven't requested.  After a period he goes off in a huff, and ignores all my commands.

This is obviously caused by the stream of noise coming into my headset from PATC, not a problem within MCE, but I wondered if any one else had experienced this, and found a solution?

Thanks, Jim
