Okay, I tried the 244 build and the stutter is gone as you said.

I still got a highfrequency pop when switching inputs. But only at first. After I messed with it a little while, the high pop stopped happening and was replaced by a low pop. Don't know why. I think it was after I started going to AM bands and back again. Doesn't really make sense.

Not certain, but I think the FM bass boost might still be there, despite my config.ini having the correct option to disable it.

I'm going to mess with the volume boost levels some more to make sure they're working.
