Question

I have tried this for HOURS. There must be a simple solution to stop the sound and unload it in as3.

This is not all of my code, but in short I am loading random sounds. I need certian vars to be outside of the function so I can reference them with other functions for a progress bar.

How do I unload a sound so I can load a new one using the same names without getting an error the second time its called?

I have two buttons in this test. A play Sound and a Stop Sound Button.

here is my code:

var TheSound:Sound = new Sound();
var mySoundChannel:SoundChannel = new SoundChannel();

PlayButton.addEventListener(MouseEvent.CLICK, PlaySound);
StopButton.addEventListener(MouseEvent.CLICK, Stopsound);

function PlaySound(e:MouseEvent)
        {
        TheSound.load(new URLRequest("http://www.MyWebsite.com/Noel.mp3"));
        mySoundChannel = TheSound.play(0);
        }

function StopSound(e:MouseEvent)
        {
        delete TheSound;
        }

HERE IS THE ERROR I GET:

Error: Error #2037: Functions called in incorrect sequence, or earlier call was unsuccessful.
    at flash.media::Sound/_load()
    at flash.media::Sound/load()
    at Untitled_fla::MainTimeline/PlaySound()[Untitled_fla.MainTimeline::frame1:21]

UPDATE…. I TRIED STOPING THE SOUND AND THEN UNLOADING IT AS FOLLOWS

mySoundChannel.stop();
TheSound.close();

BUT NOW I GET THIS ERROR:

Error: Error #2029: This URLStream object does not have a stream opened.
    at flash.media::Sound/close()
    at Untitled_fla::MainTimeline/shut1()[Untitled_fla.MainTimeline::frame1:35]

I believe I am closer. Thanks so much for your help so far.

Answer 1

In order to stop the sound from playing, you first have to tell the SoundChannel instance to stop like so :

mySoundChannel.stop();

Once you did that, you can close the stream used by the sound instance by invoking the close method like so :

TheSound.close();

Also, the delete keyword is rarely used in as3 and you should not it while some methods are trying to access the variable you are deleting. If you want to dispose of the instance that is currently assigned to your TheSound variable, you should set its value to null. This way, flash will properly garbage collect the old Sound instance that is no longer used when it finds the appropriate time to do so.
