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?
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.
My case is likely different, but solution for me was to right-click the speaker icon on the task bar and select "Sounds". I cycled through the list until I found the sound that matched what I kept hearing. In my case it turned out to be the "fingerprint scan failed" notification and I realized I kept accidentally swiping my hand over the fingerprint scanner and triggering the sound, hahaha. But same method might help you troubleshoot your case.
I had this problem today. I changed from Windows (modified) sound to Windows default and it disappeared. Just a thought
Its most likely the close program sound which only plays a sound in some sound schemes. It is triggered Normally programs closing.
But is also triggered by processes (Which you can see in the second tab of Windows task manager.)
When the sound plays you can see the number of processes drops by one so it triggers the sound. (you can see this count in bottom left)
