[wdmaudiodev] Any sample code for using the device topology to access IAudioMute?

      I need to determine if a microphone supports a mute. I have a device
which I know does not support mute. Using the IAudioEndpoint interface
GetMute and SetMute do not report any error.

      Now I am think I m ay need to use the IDeviceTopology interface to
see if the device supports a mute. Any suggestions to how to code that?

Thanks,

Andy
