Follow-up Comment #15, bug #45722 (project gnash):
Workaround included: patch #8736
This patch (_hack_) does not address the issue itself, but rather
works around it by always requesting the decoder to read in block size
that is a multiple of PCM frame size (both mono and stereo).
Which this patch, Gnash (both FFmpeg and GStreamer backend) seems to play
both `pcmplay.swf` and `pcmplay-stereo.swf` properly.
Underlying issue of frame boundary rounding (or why the decoder didn't
keep the remainder bytes for the next decoding round) should be fixed
in the each respective backend (both GStreamer and FFmpeg).
This patch should not affect other codec if their decoder do not have
framing problem similar to ones described in comment 12
