I guess I was wrong about that version of ffmpeg being sufficiently 
recent.  The PPA presumably provides only old versions for compatibility 
reasons.  If you have access to a modern version of ffmpeg (e.g., from 
Fedora), it's worth doing another test.

You also may want to try downloading with --no-tag to take AtomicParsley 
out of the equation as well.

Another thing to try is re-muxing your .m4a file into another .m4a file 
using MP4Box (apt-get install gpac), which will insert the audio into a 
fresh MP4 container not constructed by ffmpeg.  You will lose any 
metadata tags, though MP4Box supports adding a subset of the fields 
supported by AtomicParsley.

If all else fails, you can use --aactomp3 to generate MP3 files and 
(hopefully) avoid any MP4 headaches, though it takes extra time in 
transcoding.  For Radio 3 programmes, add --mp3vbr=0 for better quality. 
  You may want to transcode Radio 3 programmes in iTunes or another tool 
instead in order to get higher quality than get_iplayer delivers. As to 
the resulting audio, you'd have to decide for yourself if it's good 
enough.  Caveat listener.
