#3776: Decoding bug when playing some MPEG-4 ALS streams

When I play some mp4/als streams with ffplay (and others players based on
it) at the end of playback it produces an artificial sound like a buzz, it
doesn't happen using ffmpeg.
I use mp4alsRM22rev2 for encoding (since RM23 version produces outputs not
fully compatibile with FFmpeg).
I attach some files with this problem, the encoding parameters used are
these:
"The Velvet Machina.mp4": -7 -g4 -p -t2 -o127 -r-1
"Starbeam Antarctica.mp4": -7 -g5 -t2 -o127 -n1800 -r-1
"Crushcrushcrush.mp4": -r-1
The bug occur with a 1/3 of encoded files.
I tried too with the latest ffplay & ffmpeg builds out today, but the
problem persist.
Thanks in advance.
