[Gnash-commit] [bug #45722] Gnash emitted loud screech after playing PCM audio object

[Nutchanon Wetchasit]

Follow-up Comment #7, bug #45722 (project gnash):

I have made a dummy patch for showing some diagnostic information on
`AudioDecoder.decode()`, see the attached
`show-sound-decoding-diagnostic.patch`.

After applied the patch, I have tested Gnash with both FFmpeg and GStreamer
backend on both `pcmplay.swf` and `pcmplay-stereo.swf`. Result logs 
(verbosity 2 + action error log) and audio dumps (if applicable) from
each cases are attached as `pcmplay_gnash0.8.11dev-dc51f53_diagnostic.zip`.

Note: audio dump from `gnash --audio-dump` might not be read properly in
some sound editor/player. This issue was reported separately as bug #45887.

(Audio dumps attached above are already fixed using AVconv,
so they could be opened directly in an editor like Audacity)
