Sound "pops" and begins to squeal until restart.

Recently, certain sounds on certain games have caused the sound on my computer to "pop" and begin to screech/squeal/high pitched noise which lingers until I restart the computer. The noise is both with headphones and speakers and you can NOT hear the noise when you turn the volume down. As soon as you turn the volume back up and it makes the "sample" noise the screeching begins once again. What is the problem here and how do I fix it.

*Note* This issue started recently, one game I played for over 200 hours never had this problem but now when I perform a certain action which makes a certain noise, the sound pops. When I restart my computer the sound finally stops and I can resume using my computer normally.

Time to talk to this PC's maker.

This can be heat related or a PC in need of repair. Your post left out PC details so the answer is to talk to its maker.

Dell XPS 15

Intel(r) Core(TM) i7-4702HQ CPU @ 2.20GHz

(RAM) 16.0 GB

64-bit OS, x64-based Processor

Intel(R) HD Graphics 4600
NVIDIA GeForce GT 750m

What else need I include?

(NT) BTW This is a laptop

Does a factory restore clean this up?

If not, you talk to its maker about repair costs.

I don't think I want to factory restore...

That would be a whole lot of backing up to do, any other ideas?

- Collapse -
Arrange for repair.

The factory restore would have told us if it's some software or driver issue. If you are serious about diving into this, you would clone the drive, then put in your clone copy and factory restore then see if the problem is there or gone.

Now we know it's software. It costs about 50 bucks for a 500GB laptop drive so to me this is a bargain compared to repair counter costs.

Now I can compare drivers and what's running on working and non-working drives.

Painful but it could find what's up IF it's software and drivers.

So you have no backups?

And you don't want to do the work? Then it's very hard to help you.

- Collapse -

If you have not already done so at least backup 'your stuff'.

You have a machine with a problem.

It might croak at any time and then your screwed.

Make plans for a rebuild from bare metal.

Thanks anyways.

For some reason my whole post didn't come through. You said it could be heat related I'm thinking that is the problem. Guess I should try investing on a cooling pad or something and trying to clean up the fans.

- Collapse -
Wait, you are not cleaning on schedule?

Here I've changed from every 3 months to every 1st or the month for canned air to the laptop vents. The reason for the schedule change is the sheer number of clogged heatsinks I've seen in the field.

I know a lot of laptop owners that never knew these machines need regular maintenance. My bet is that 3 months might be enough but gaming laptops and higher performance models don't react well to even the slightest cooling loss. So back to 1 month. Let's call it the 1st of the month routine.

Issue Persists.

Thought I was good until I watched this video How To Be Ninja Fails! (BTS) at around 1:11 while he is playing the piano my speakers/headphones begin to squeal until I mute the video or turn off my sound, because any sound made from that point on makes the high pitched noise continue. When I restart my computer everything is fine again. I tried watching the video multiple times and the high pitched squealing begins at that same point every time. Something else I noticed, it seems to be only the left earphone/speaker.

It's back to the maker unfortunatly.

The factory reset and the above tells me it's time to get it fixed.

Remember I take it at your word this is a factory installed load and all drivers are what Dell tells you to do.

I'm Confused

"Remember I take it at your word this is a factory installed load and all drivers are what Dell tells you to do."

What exactly do you mean here?

Sorry... I haven't really understood a lot of what you've said this whole time, but thanks for continuing to check up on my post. Not sure if English is your L2 or if I'm just not reading it what you write correctly.

he means;

It's a hardware problem and no amount of software changes or reloading is going to change it.

Try a LIVE DVD of Linux, such as Mint, Ubuntu, Zorin. If it also does the same thing from a totally different operating system, then you can be certain it's NOT software related.

Sounds to me like you have a failing sound chip on the motherboard. Your fix without factory repair would be something like this.

Self Repair

How safely/easily could I replace the sound card myself? Is there a huge risk in damaging all the internals if I were to attempt to do so?

This Is What's Inside

What happen when you disconnect the microphone?

Just as a test, because the sound you describe sounds like feedback to me.

- Collapse -
most sound is on the motherboard now

but if you have a free slot, you can put a sound card in and use that, or use the USB type soundcard.

I like the suggestion about the location of the microphone being too close, creating feedback. Wish I'd thought of it myself. anytime a mike is too close to a speaker you can get that squealing.

I Disabled The Microphone

Didn't seem to help.
I guess I'm using Ryan Higa's video as a test now because that spot is still setting off the high pitched sound. I like the idea but this issue happens with BOTH the internal speakers AND earbuds (Left side only on both). Perhaps if I uploaded a recording of the sound someone could find it useful?

Another Note

I just tested it on a fresh boot up, everything cool as a cucumber and it happened. I think we should rule out heat (unless of course heat caused a now irreversible problem).

Do you set a cellphone down near it? Speaker wires can act like antennas too, maybe picking up some nearby broadcast and adding that as noise to them. Try using the computer in a different spot. Turn off wifi on router and use wire for awhile, see if the wifi signal is interfering. If you can't track this down to some broadcast interference, you just have to accept the sound chip may have gone bad on the motherboard.

- Collapse -

Yes, my cellphone is typically near by, I'll try turning it off and moving it elsewhere.

I just find it really weird that only very specific sound frequencies (such as that coming from the piano in the video I linked) cause the problem. Most of the time there is nothing wrong, I've gone several days without setting off the sound unless I go looking for it in places that have caused it before.

Unfortunately this laptop has no Ethernet, but I'll try turning off the wifi and attempt to find the sound in an offline game.

I have only what you post here to work with.

If the OS delivered and configured as per Dell is bombing out and there are no other factors like you are running torrents, using drive emulators and such, then it's not a software failure. It must be hardware.

There are clients that refuse to do a factory restore and our office will offer to look at it on a per hour basis with no guarantee. A small percent will pay for that deep work. Here you have done a little but may be thinking it's something everyone knows how to fix. Well, that's partially true. I know to scan for bad things, head back to stock and if it looks like OS damage or we get even a whiff of OS issues, we slip in a blank HDD and do the factory restore or install. Then we know where the issue is.

As to English. I write as if I talk to our techs. You as the person who has to repair the machine may not understand a phrase so go ahead and ask for clarification.
