Can I identify what process plays random beeps in Windows 7? [duplicate]
Solution 1:
If this happens frequent enough, you could right click the audio icon in the notification area and click on Open Volume Mixer; there you can see which application is currently playing audio. There is no history available for this, and it is really impractical to figure out the sound file given that it might not have an obvious extension. Process Explorer allows you to search for open handles, just hit CTRL+F and search for common extensions like .wav and .mp3 and so on...
