Details:

Hello, I have used Gnash 0.8.9 and Gnash 0.8.10 to play flash7 file that tries
to invoke sound within ActionScript 2.0, by using this code

snd=new Sound(this);
snd.attachSound("beep-note");

trace("sound: starting (repeat 0)");
snd.start(0.0,0);

It supposed to play sound from offset '0.0' with repeat value '0' which Flash
Player will treat it like a repeat value '1' (aka. play the sound once)

But on Gnash, it was treated as an infinite-looped sound, which was an
incorrect behavior.

This is a 'correct' result from Macromedia Flash Player 7
You will notice that sound was played only once.

This is a video result from Gnash 0.8.10
You will notice that sound was looped infinitely, and there was also a gap
between loop, which seems to be a symptom of bug #24481 (ActionScript sound
loop gap)

These are my dummy flash files (created from Flash MX 2004), accompanied with
source code, and also attached here.
(These videos was recorded using soundrepeat.0.swf [SoundRepeat0.as], but
other files will behave the same)


Note #1: both zero and negative repeat value was treated by Macromedia Flash
Player as it was '1'.

Note #2: both zero and negative repeat value was treated by Gnash as it was an
infinite repeat (any negative value will get the same video result as above)

Gnash: gnash_0.8.9-1~lenny and gnash_0.8.10-1~lenny from getgnash.org APT
repository (both yield exactly same result)
System: Debian GNU/Linux 5.0 Lenny on i386
