There have been numerous issues with the audio level being
too low with the Roady.

P.S. Missed that -- There is a line level adjustment on the Roady if that's
any help, but since I've not yet tried the Roady in the airplane I can't
speak with authority -- line level is great at the default, 5, for good
speakers but I had to lower it to 3 so that cruddy speakers didn't buzz.
