Probem using mute audio using MMAPI...

Hi all,

I am doing audio operations with MMAPI. I am trying to Mute and Remute the audio. The following codings are not working. Anybody help to solve the problem. Coding is as follows

if(vc.isMuted())
{
setUnmute();
repaint();
}
else
{
setMute();
repaint();
}

public void setMute()
{
try
{
if(vc == null)
vc = (VolumeControl) player.getControl("VolumeControl");
vc.setMute(true);
}
catch (Exception e)
{
System.out.println("Error = "+e);
}
}

public void setUnmute()
{
try
{
if(vc == null)
vc = (VolumeControl) player.getControl("VolumeControl");
vc.setMute(false);
}
catch (Exception e)
{
System.out.println("Error = "+e);
}
}

Thanks in advance.

Regards,
Dhanalakshmi.
