Mystery sound

A program on my computer keeps making one of two different sounds. Now, this is not as simple as you might think it is to solve. First off, I cannot describe the sounds very well, but they are extremely annoying considering I have had it for longer than I can remember. It sounds like a high pitch sound, either becoming progressively higher or progressively lower, lasting for only about one second. It happens entirely randomly, there is nothing I do that relates to when the sound is played, sometimes it plays in the middle of the night while my computer is idling but more often when I am using it. I can’t just close a program, wait for it to happen, and close a program and figure it out that way because often my computer goes weeks without playing the sounds and other times it goes just a few minutes.

Does anyone have any ideas? Perhaps even some sort of program I can run that will log what programs play a sound, when it is played, and where the sound file is?

It’s not just a faulty speaker or sound card or driver or motherboard. I’ve been through several sets of speakers and headphones and even got a new motherboard during this frustrating period of time I have had this problem (for different reasons, it was already obvious to me that none of those components were the cause of the sound). I doubt it’s a virus either, I’ve been through lots of virus scans.

Sounds like it could be one of the cooling Muffin fans inside your pc doing that. Might check that out if you already haven’t. :slight_smile:

I thought somebody might say that… I can say with confidence that that is not the case either. I’ve been through my share of fans, including case fans, power supplies and the new processor fan that came with the processor that came with my new motherboard. It’s definitely a sound coming out of the headphones/speakers. I last heard it in my noise-cancelling headphones, too (crisp and clear). And it’s volume seems to vary with whatever my speakers and/or Windows volume are set at.

EDIT: what’s a Muffin fan?

All sounds used by avast are stored into its folders…
For instance, \English*.wav ::slight_smile:

Hmm… Doesn’t seem to be Avast that’s making the noise then :frowning:

Softwares use sounds, not noises.
If you disable the speakers, will you still heard the sound? If so, other piece of the hardware is making it…

Sound is noise. Anyway I am quite sure that it is a program on my computer that is making the sound. I’ll try to call it sound from now on if you wish, it’s not coming from anything but speakers or headphones. I can’t just turn them off and wait for the sound to not play, because, well, it’s not exactly scheduled… I like using sound sometimes…

I thought I had a mysterious sound a while back, but I figured out that it was my Epson printer shutting down. Often the sound did not occur until a half-hour or so after I pushed the stop button. Could you have some hardware doing something similar?

I doubt it, I didn’t even have a printer until recently, and don’t have a scanner…
