Found a working solution, aac audio, changing the ac3 audio profile line to:
ffmpeg-audioac3=-acodec aac -ab 256k -strict experimental -cutoff 15000
Produces good results, good audio, good video with default settings in the profile.
Not sure what was up with MKVMerge but it is working with aac.
Onward!
