Audio is done in hardware inside of the RRC, using the red straps. If you didn't push the straps all
the way in the socket carefully, then they can easily get loose when you move the RRC. I would first
open up the RRC's and make sure that these are properly in place.´
If you are using a TS-480 or K3, I could test your system from here to see if audio is working ok. First
step would however to do the above, although it would be more likely that the problem is at the radio
RRC that was physically moved.
