If you want to enumerate audio devices, it becomes very easy by using SlimDX . It requires DirectX to be installed in the computer though.

For example, to enumerate the audio capture devices:

 DeviceCollection coll = DirectSoundCapture.GetDevices();
 foreach( DeviceInformation dev in coll ) {
    ...

 }

To enumerate audio playback devices:

DeviceCollection coll = DirectSound.GetDevices();
   foreach( DeviceInformation di in coll ) {

   }

The DeviceInformation class has a Description property of type string . It also has a DriverGuid property of type Guid that enables you to "select" the device to perform either audio capture or playback (that can also be done by means of SlimDX).

EDIT: a method using Winmm.dll Please take a look at the following entry in Code Project. It builds an enumerator using Winmm.dll only.

Hope this helps!
