Maestro has audio clicks and buzz

Two possibly related Maestro only problems:
  • Disconnecting the AC power (with a connected bay battery) forces a drop of radio connection.  i.e. a mains failure disconnects the radio.  It will reconnect OK
  • As soon as the radio connects the Maestro speaker and phones connection starts with a combination of, fairly loud, background buzz with overlaid crackle.  No controls will affect the sound (AF/AGT/RX/TX/etc).  Then it may stop and normal operation starts. 
I am expecting a trip home may be necessary but want to exclude software.  I have seen no mention of this here so it is likely a hardware problem; just unusual to be present only while a radio is connected; sound is gated on when connected and very quiet without a connection.

An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
