OS X :: Internal Mac Speakers Making A Sharp Popping Noise?
Jan 9, 2010
Occasionally I'll be listening to music or just changing the volume and a sharp popping sound will occur from the internal speakers and then they shut off. No sound can play it all. To fix the problem I just have to reboot and then the speakers work fine. Does anybody know why this happens?
This happens on my iMac sometimes and it just happened on my new MacBook Pro and I'm wondering if it's damaging the speakers in any way.
Edit: I don't remember what I was doing on my iMac to cause this, but I do know what caused it on my MacBook Pro. I was recording my canary singing (don't ask why) using Quicktime Pro, and then listened to it (it worked fine). I imported it into GarageBand to crop it and when I previewed it there to figure out where to crop the file, my speakers popped and GarageBand gave me a warning about the current track not being optimized or something. Note that never happened on my iMac.

Yesterday my speakers stopped working. It's not software based, the audio drivers are working properly. Whenever a sound that is over a certain volume is played, you can hear a pop come from the speakers. For instance, if I play a song that has fluctuating volume, every time the volume goes up, there's a pop, and every time it goes back down, there's a pop. The volume the computer is set to doesn't effect this. Even if it's muted, there's still a pop that's the same volume as if the volume is turned up all the way. Any ideas what could be causing this?

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

Before making a slideshow in iDVD the pics were sharp (& in preview), but after burning the show to disc the pics had become fuzzy. How do I keep this from happening?

My new 13.3" Unibody MacBook Pro has been great up until now. I've had it since September and it's worked without a charm. For some reason, as I went to close the hinge (slowly) today, it made an extremely sharp cracking sound, as if the screen had broken off. I had mini-heart attack on the inside, thinking that the screen of my MacBook Pro had just broken. I quickly opened the screen to see that nothing was damaged. I went to close it again and I went past the point that the cracking noise happened at (it sounds like it gets caught). As I kept closing it, the cracking noise happened about 3 more times. No noises come from it as I open the MacBook Pro, but when I slowly close it, it cracks (really loudly).
I've been closing the lid really quickly now, and no cracking sounds occur when I do that. Do you think it's a loose screw or something like that? Should I take it into an Apple Store to see if they can fix it? This laptop is like my baby. I somewhat temporarily alleviated the issue by pushing a piece of paper through the hinge and out the back of the laptop an pulling it back and forth. The hinge worked well for about 5 times, then started cracking again. Now that I think about it, it might be caused because it's been on for about 11 hours. I've never worked it this hard before. I'll try again after I go to sleep, and see if the problem has gone away. the problem is a little better now. There are still tension points (there are less though), but they don't crack very often as I go past them.

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

Situation: no sound out from speakers in admin and user account and newly created account. Headphones work, startup chimes work on speakers.
Go to Sound in Preferences and only shows Digital Out for output. Should show Internal Speakers. Ran Diskwarrior and Applejack and zapped pram. Took mac apart and confirmed speakers wired correctly which is verified by the start up chimes being audible on the internal speakers. tested all accounts and created new account all with the same results. Did search of Google and MacRumor. Found one unaswered post indicating same problem. Had same problem with another macbook pro, ran same steps, take apart, confirm wiring setup, Diskwarriored, applejacked and zapped pram and it fixed the problem. I'm not sure what else to try. Did check Audio Midi Setup util and it also did not see the internal speakers.

Whenever I put my mac mini to sleep, my speakers will make a pop sound about every second. The speakers are powered via usb cable plugged into the mac but they'll also pop if plugged into my dell. There's no popping if the speakers are plugged into my sleeping dell, when my mac is on, or if I turn the mac mini off.

I just received my new MacBook Pro (2.4GHz) to replace my older CD Macbook Pro from 2006 which was suffering fan problems.
My new MBP is great and faster, with the exception of a really annoying "popping" sound that is coming from the left hand side of the laptop. It's sporadic and might happen every few minutes, or every 30 sec. or varying lengths of time in-between "pops."
I searched the forum hear and didn't come up with virtually anything at all, but the Apple Support Discussions had several threads on the topic, most pointing to the Hard Drive and the sound possibly coming from the heads parking on the disk.
Could anyone offer any advice on the subject? I just got this brand new MBP from AppleCare and really don't want to have to go through all the work on getting another replacement if this sound is normal.

I was messing around with Garageband today with my instrument and then suddenly there was a loud pop, and then audio went out. What's going on?

I started to notice a "popping" noise (about 1 Hz) when I got external speakers for my Mac Mini. It occurs when the Mac is sleeping and the external screen is on (but sleeping its own "sleep"). If I disconnect the analog audio out (from where the external speakers take their signal) the popping ends. If I connect headphones to the same jack, I hear no popping in them. If I hit the power button on the external screen and power it down, the popping ends. It will not return even though I power the screen on again.If I disconnect the USB cable that power the speakers from the Mac, the popping ends, but returns when I connect again.

I was reluctant to update my 27inch i5 iMac with the new graphics card firmware update since I wasn't having any flickering issues. I finally caved in and did it thinking that nothing bad will happen, well of course something did. Ever since I updated it yesterday my computer makes a distinct and random popping sound from the speakers, it is soft but audible in my quiet room when I am working and it is driving me crazy.

2 days ago i received my new mac pro 6-core 3,33GHz...now something really weird and super annoying is going on with this computer...From time to time there is this really loud POP trough my speaker. I'm absolutely 100% sure this has nothing to do with my amp. cables or whatever and its definatly a problem with the MacPro, i know because of the following:
Plugged in new cables, removed every installed software, plugged onto different amplifier, when there are absiolutely no audio cables plugged into the computer and when i use the build in speakers of the mac pro i still hear the POP/distortian like sound, and finaly even took it at my friends house and tested the machine there on his audio instalation...problem remained! not knowing what to do next i decided to go and see a very good technician (music instruments and studio recording) and told him about the problem, he imediatly stated that it "could be" because of the harddisk drive giving like electric impulses or whatever that causes the distortion...or that the sound card or audio chip set waking up from sleep and every time it does there is this loud POP?..................

I have an early 2008 Mac Pro. For the past 6 months or so, it has been making a whirring, clicking, chirping noise. It does this constantly, no matter what I'm doing. I replaced the hard drive, but that didn't help. The sound appears to be coming from the rear of the computer, near the top. (where the power cord plugs in).

Whenever an application uses the internet, such as Opera, Safari or aMSNn the speakers create a static, crackling sound thats incredibly annoying. The only way to get rid of it is to shut down the app that makes it (usually aMSN or Safari) but it may start again soon. It must be an issue wtih the speakers as it doesn't have any effect on headphones.

Yesterday my PB from 2004 started to make a noise like an angry mosquito. Is it the hard drive dying on me? This is just a take-along-when-I-need-to-be-mobile computer, there's nothing there that needs to be backed up. But I wonder what the noise means.

I was just downstairs in my basement using my macbook and I decided to come upstairs and when I got up here I noticed that my fan is making a weird buzzing noise. I can tell it is my fan because when I make the fans spin faster in smcfancontrol the noise gets louder. Could this be something that is in the fan or could this be a more serious problem? I can take the back case off and check but I just wanted to know if this could be a serious problem with the fan. Is there any chance I could have bent something by carrying it wrong?

My Mac Pro 8 Core 2 x 2.8 GHz Quad-Core Intel Xeon with Leopard 10.5.8 started making a humming noise about a month ago. The humming noise is very consistent in pitch and is always humming whenever the computer is on, except for when sleeping.

My iMac 20" G5 (PPC, working with Tiger 10.4.11), bought in April 2006, has the following illness:
When I work locally, it functions fine. When I go into Internet, it starts purring and whining.
When I watch a video on YouTube, for example, the purring and whining increases and finally the screen blacks out. With a mouse click, the screen comes back but goes out again immediately.
After shutting down the system and giving it some rest, everything starts working again normally, but only until I go online.
I have tried to use Disk Utility, but the install disk that came with my Mac gets ejected.

My MacBook Pro just started to making a clicking/ticking noise. I am assuming that it has something to do with the fan because when I shut my computer down, the noise stops, but once I start my computer back it, it starts once again.

My macbook pro was on while I was sleping and I think the power got disconnected and it shut off on its own. I woke up to it making this ping noise every 20 -30 seconds.
Here is a link to the YouTube video: [URL]
The computer works fine I've tried to turn it back on and off and it works ok.
