c# Stop Audio sound

Hi,

In my background task I play sound continuosly:

      private void bgw_DoWork(object sender, DoWorkEventArgs e)
        {

            myaudio = new Audio();
            while (true)
            {
                myaudio.Play(@"C:\windows\media\ding.wav");
            }
        }

When I click cancel button, in the completed task:

       private void bgw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            myaudio.Stop();          
        }

But the sound is not stopped. do you know the reason?

Thanks,
JT

Hi,

Here is working code for your reference:

 
private void btnAudio_Click(object sender, EventArgs e)
        {
            SoundPlayer wavPlayer = new SoundPlayer();
            wavPlayer.SoundLocation = @"C:\WINDOWS\system32\LoopyMusic.wav";
            wavPlayer.Play();

            wavPlayer.LoadCompleted += new AsyncCompletedEventHandler(wavPlayer_LoadCompleted);
            wavPlayer.LoadAsync();

        }

        private void wavPlayer_LoadCompleted(object sender, AsyncCompletedEventArgs e)
        {
            ((System.Media.SoundPlayer)sender).Stop();
        }

Open in new window


I hope this helps. Let me know if you need more help.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Hi,

Make sure sound file exists on this path i.e. "C:\WINDOWS\system32\LoopyMusic.wav"

Hi,

I checked c:\windows\media folder in my notebook, I found. ding.wav file. And go this folder (c:\windows\media),
and select ding.wav, and click play. It plays fine.

Do you know why it does not produce sound on the notebook?

Thanks,
JT

Hi,

If you play ding.wav, it's simply a beep. Try referencing some other file.
Also, this way of playing sound is standard and is not specific to any machine. May be you can check some machine configurations...

Thanks.

Hi asim,

Thansk.Your solution does not play sound continuously. Since during uploading file, I'd like
sound playing on until the end of file upload.
Do I miss something here?

Hi,

To play sound continuously, you need to use PlayLooping() method instead of Play();
So code will become:

private void btnAudio_Click(object sender, EventArgs e)
        {
            SoundPlayer wavPlayer = new SoundPlayer();
            wavPlayer.SoundLocation = @"C:\WINDOWS\system32\LoopyMusic.wav";
            //wavPlayer.Play();
            wavPlayer.PlayLooping();

            wavPlayer.LoadCompleted += new AsyncCompletedEventHandler(wavPlayer_LoadCompleted);
            wavPlayer.LoadAsync();

        }

        private void wavPlayer_LoadCompleted(object sender, AsyncCompletedEventArgs e)
        {
            ((System.Media.SoundPlayer)sender).Stop();
        }

Hi asim,

Yes. I can play any media sound on my note book: mp3, wav,...
But my program is not producing sound on this notebook.

Hi asim,

if i have a different wave file, and load it at run time, suppose I save it into my resources folder,
what api call to load this file from my project (subfolder resources)

Thanks,
JT

It's working on my machine and also on your desktop machine. So, this has to be configuration issue - as I wrote previously!
