    mciSendString("close recsound ", "", 0, 0); 
    Computer c = new Computer(); c.Audio.Stop();


}

protected void btnRead\_Click(object sender, EventArgs e)
{
    //Read
    Computer computer = new Computer();
    computer.Audio.Play("c:\\\\record\\\\record.wav", AudioPlayMode.Background);
}

}

This is the basics of ASP.NET. If you play audio using Computer.Audio.Play it will always run in the server. What you have to do is to download the wav file to the client and then invoke the browser media object installed to run your wav file. For simplicity you can also use

Body BgSound ="~/record.wav"

I recommend to read basic books before you do programming in Web Environment, as there is some problems in the basics of this environment. Hope you understand. :cool: Also on your problem if you are using BgSound or anything, always refer to the Virtual path, as Physical path of your server is different from the clients. ;)

Yes. Say you upload a file into the server say abc.wav save this file into a directory which is within the virtual path. say c:\mywebsite\xyz folder. so that you can call http://yourserver.com/xyz/abc.wav Now create your webpage such that it plays audio using this path.. not your original physical path. Finally take any of the different steps mentioned here to play your sound in the browser: http://www.phon.ucl.ac.uk/home/mark/audio/play.htm[^] Hope you understand this. :)
