If I had to take a blind guess ... I'd say it is far more likely that the problem was not with the radios themselves, but with the audio selector ... you can even route the audio to the speaker if your headsets fail ... and of course there are more than enough mic's to choose from ... however, if the ACP is hosed, all bets are off.
