2.96 failing to produce playable files

[Charles Johnson]

I decided to revert to 2.96 after 2.97 failed for me (see postings 
above) and now even that is failing in that the .m4a file is unplayable, 
containing, seemingly, silence with the odd crackle here and there. My 
command was as below and the log file mentioned (seemingly error free?) 
is here: http://sprunge.us/RhdI

get_iplayer --mode=flashaaclow1 --start=0 --stop=0 --pid b084tjt3 --force --verbose --overwrite 2>&1 | tee b084tjt3.log
