are you using the same sound in both the working and non-working fla files?

are you using the same method (eg, attached to timeline) in both?

yes... its same sound. same method.

my be my project is corrupt. because, I try to use the same project but the results of the previous save . and it runs . but there is another problem . I use 2 swf file to load movie . swf first making in adobe flash. swf second making in another program. The second swf file that can be heard the sound of his music . but if it is loaded in my main project . only that of the adobe flash swf that can be heard the music. why?? I am confused !...

there are many reasons a swf would work when played but fail when loaded.  the most common problem is the use of _root in the loaded swf.

adding

this._lockroot=true

to the loaded swf solves that common problem but it doesn't solve all problems.
