[Gnash-commit] [bug #35984] I Love Traffic is not able to mute it's sound on Gnash

[Nutchanon Wetchasit]

Follow-up Comment #3, bug #35984 (project gnash):

This is still reproducible under current git version of Gnash, and is not
really specific to adjusting volume _while_ the sound was playing.

I have created simple SWF files (Flash 7, using MTASC and SWFmill) that tries
to play embedded sound with adjusted volume from ActionScript in five style:

# No volume adjustment, as a reference: `soundvolume-ref.swf`
# Reduce volume right before running `Sound.attachSound()`:
`soundvolume-preattach.swf`.
# Reduce volume right before playing sound: `soundvolume-preplay.swf`.
# Reduce volume right after started playing sound: `soundvolume-playing.swf`.
# Reduce volume 1 second after started playing sound:
`soundvolume-1secplayed.swf`.

It turned out that changing embedded sound volume using all of the way
mentioned here *have no effect under Gnash*; they all played in full volume.
(All of them works in expected fashion when running under Adobe Flash Player)

Test SWF files, source code, and sound (PCM 44100 Hz 16-bit Mono, 5.0 sec)
are attached as `soundvolume.zip`. Comparison screencast and logs will
follow.

Gnash: 0.8.11dev (git 4c03566 19-Dec-2015)
System: Debian GNU/Linux 7.0 Wheezy i386

Flash Player: 9.0r45 (9.0.45.0) Standalone
System: Microsoft Windows XP Professional SP3
