I'm having some audio problems with the Mooney M20R pack.Basically I can hear ATC audio, but it keeps cutting in and out so I only hear fragments or individual words at a time.I've tested other planes, for example the 172SP with G1000 and it works fine. Also, the Mooney with G1000 panel works fine. It's the standard Mooney M20R with GMA 340 audio panel that seem to have this audio issue.Any ideas on how to fix this?
