Windows 7 – What process is making that sound?

My Windows 7 system makes an intermittent ding sound (like a single chime, or bell).  I don’t know which process does it.  So, my question is: Is there software/method out there that can tell me which processes are currently sending output to the sound device?

Solution:

Fire up the volume control which will list all applications that recently made sounds. If you have it open while the sound plays you can also see which application is doing it.
