Popping noise on sleep

This is BRAND new problem for my 6 mo. old Powerbook. I have not tried it with the powercord in, but with the powercord out, after I close my book to make it sleep, a wierd popping noise occurs (rather loud) and as the noise pops, the blue 'sleep' light comes on. It's rather unsettleing. Any ideas?

My Powerbook G4 12" makes a popping noise before and after (there is usually a delay after a sound is played) a sound is played through the built-in speakers. It could be that when your Powerbook goes to sleep, the speakers were activated and then they are "turned-off," which results in a popping sound. To test if this is the case, plug in a pair of headphones and put the Powerbook to sleep. If it doesn't make the popping sound, it is just the built-in speakers. If it still makes the sound, then the problem lies elsewhere.

Popping noise while sleeping

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 eventhough 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.
Any clue to what this problem comes from? Some kind of ground loop?
/BE

Seems we've isolated the problem to Electrical at least. Sounds like a Ground loop somewhere.
See this nice article...
http://www.soundonsound.com/sos/nov04/articles/computerproblems.htm
Audio equipment which uses a double-insulated design needs no earth connection, and so is less susceptible to earth-loop problems. Such equipment will often use two-core mains cable, which has an oval cross-section, and the mains plug will sometimes use a dummy plastic earth pin, as shown here.
Disconnecting the earth wire inside a mains plug might solve an earth loop problem, but it's a dangerous solution, because you're removing an essential electrical safety measure.
And my best guess at this point is the PSU for the Speakers.

Loud Popping Noise when wake from sleep

On my new iMac CD 20" there is a load popping noise that comes from the speakers when I wake it up from sleep. Also, the hard-drive or the super-drive clicks a few when waken from sleep. Yesterday there was a static noise coming from the speakers while I was using the machine on the web, it was load enough to be annoying, I restarted it and the sound went any. I am wondering if any others have noticed this problem and should I take it back for a new one.
My wife has even said that the sounds don't seem right.
Any feedback would be great!
Thanks.
20" Intel iMac and 12 P-book- 867 MHz Mac OS X (10.4.4)

I conducted some tests on my iMac, and the problem, as it were, is related to having external speakers connected to my iMac. When I unplug my external speakers (JBL Encounter), I do not hear the pop upon waking my iMac from sleep. When I plug the speakers in again, the pop returns. I do not hear the pop when I mute the speakers before putting the iMac to sleep, either.
To rule out other devices, I unplugged all external devices and then reconnected them one at a time. Only the speakers triggered the pop.
I don't think this is a defect necessarily, even though I never heard the popping sound when waking my iMac G5 from sleep (with the same set of speakers). I think it may, as I suggest above, have something to do with the change in processors.
I may call Apple just the same to see what its tech. support people have to say on the matter.
Do those others of you experiencing the popping sound also have external speakers?

Popping Noise Then No Sound

I have a mid 2007 macbook with 10.4.11. I was listening to things on the internet (youtube, etc.), and it was working fine. I shut off the sound (F3), and a while later I wanted to listen to something else. I pressed F3, and I got a loud popping noise instead of the normal one. I pressed it again to shut off the sound, and got the same noise. I did this a few times, and it kept happening. I tried listening to sound with it turned all the way up, and there was no sound coming out of the speakers. I closed it to look at the speakers and see if there was something in them or something (there wasn't), and it went into sleep for a little while. When I opened it again, the sound was working perfectly fine.
It's still working like usual now - should I take it to Apple and see if something's wrong, or was this just a one time thing? If it happens again, should I just close the top again? What caused this?

Even if it's fixed now? Because it's been working fine since then.

Popping noise on Creative 6600's / Audigy

Hi there,
I've been using this configuration for a while now and haven't had any problems with it. Until now.
The speakers seem to have developed an annoying popping noise, but it only happens in 3 out of the 6 satellite speakers. The noise is the same level no matter what the speakers are set to on their wired remote, and only stops once the speakers reach volume 8, and then the sound is awful because the speakers can't actually cope at that level.
I've taken apart the little remote and cleaned everything out which seemed to stop the problem for about 60-20 seconds, then it started again.
The noise will stick around for a few hours and then dissapear for a couple of minutes ata time, before coming back to annoy me again.
Does anyone have any ideas on this? Thanks in advance...

MacBook: line out noise when sleep mode

Hi,
I have my MacBook hooked up to my hi-fi system with a line-out to cinch cable. whenever the macbook enters sleep mode or is turned off, a very loud noise is generated, as if I would have plugged the cable right off the computer.
Is there any way to circumvent this annoying noise? I fear that the permanent explosion-like-sound might damage my speakers.
Thank you!
Mark

thenk you for the answers so far. What I am doing at the moment is not perfect, because it does not work when I forget one step:
-I activate sleep mode only manually now
-before, I switch off the receiver (otherwise, the loud "pop" noise is still there)
I will try with a better quality-cable, but I can only imagine the sound quality of the loud "pop"-noise to be 'crystal-clear' with a better transmission (optical cable doesn't work on my system)
Thank you,
Mark

Macbook Headphones Pop Noise

Hello,
I recently purchased a Macbook 13" Retina. Thus far, the machine has been working wonderfully. However, I was listening to an online course via headphones today and noticed that, if I stop or pause the audio... after 30 seconds to a minute or so, there is a popping noise. Seems to happen each time there is any audio and it is then stopped.
Not a big deal, but I want to make sure there is nothing wrong with my system. From what I've researched, this may be the audio driver going to sleep to save on battery life. If that's all it is, I'm fine with the sound. Has anyone else with a Macbook noticed this or has any other information?
Thanks,
Tom

This sounds like a hardware problem but first lets try going to "Audio MIDI Setup" in your Utility folder and checking the settings.
An just to make sure you plugged your guitar into the mixer (no amp in between), mixer (line out / tape out) is plugged into macbook Line in.

Why is there a popping noise when I cut between angles in a multi cam edit? How do i get rid of it?

I shot an interview. I recorded it on an h4n-One person was on channel 1 and the other was on channel 2. When I cut between them in a multi edit it creates a popping noise. How can I get rid of this and/or prevent this from happening?

I had this.. I didn't cure it I just slipped the edit until it went. Not always possible. What I would do on avid or fcp 7 is add a dissolve to the audio tracks.. So you could do that in the fcp x way

"Popping" noise w/ Audigy 2

Hi,
I have had this constant, periodic popping noise through my 7. Creative speakers with my Audigy 2 ZS whenever I load windows and mostly when I have two sounds playing at once ie. Games and Winamp... please does anyone know how to fix this? It is very annoying...
The popping gets louder when I turn the speakers up and down when i turn them down ...

"The popping gets louder when I turn the speakers up and down when i turn them down"
That's normal for a volume control. How about a search on this forum, because what you asked, is asked before here really many many times.
I've also answered many many times, almost with the same answer.(irq/dma sharing of Motherboard&Windows. Put soundcard in a pci-slot that don't share with other equipment that is used at the same time.(like video = audiocard+graphicscard at same time, so you don't want these too cards to share irq/dma.)
well do a search on this forum for popping audigy, and you'll find tha answers.

How do you solve popping noise??

Does anyone have a solution, or can suggest a course of action to address the popping noise that occurs when my macbook Pro's speaker turns on, say when launching a song from itunes. It is not super annoying yet. But it would be nice to solve. Is this a 10.4.8 thing or software glitch, or hardware related. I have a new MBPCD2 2.16

Are there any technicians from apple that review these forums? I have the issue of the popping noise and was very concerned, but it make sense that for power saving that the speakers get de-energized.
Should I be concerned?
I just bought this MBP. You think that something that costs this much, wouldn't have this kind of issue. I've been faithful to PC for 15 years and finally converted to MAC because I was getting tired of PC issues (like this) It is extremely pleasing to fire up my mac and not have to work on it, check virus definitions. I kinda don't know what to do with my time now!!!
Thanks in advance.

Pop Noise from Audio Out While Using iTunes 9.0.1

I have a black MacBook with Leopard 10.5.8 and iTunes 9.0.1. I have a a pair of computer speakers plugged to the MacBook's audio out minijack. Every time I run iTunes to play my music everything goes fine until I stop the music (you know with the space bar or the stop button). 30 seconds after I stop the music a loud pop noise comes up and stops, as if some electrical device was receiving a charge of electricity. When I play music back again on iTunes, the same noise comes up again with the music and goes away immediately while the music continues all right.
This is what I have done so far:
Change my energy saving parameter to several different configurations (perhaps the hard drive stopping when unused was the cause) but none fix it.
Turned off Airport...did not fix it
I timed the pop noise and it happens exactly 30 seconds after I stop my music on iTunes and then again 30 seconds after music has been stopped unless I start playing the music back again and the pop noise sounds again.
Any help would be appreciated as I use my MacBook to play music sequences for my band (I am the drummer) so the darn noises come through our PA system (and I also tried my small computer speakers and it does the same thing).
Thanks,

I spent a good amount of time reading several discussions. Apple is aware of this issue but no solution as of yet. The popping noise is "normal" behavior and happens because of how the sound system is programmed in the computer.
The solution (sorry for the bad news) is to not use the audio out minijack at all. Instead, get an audio interface that connects to your USB port and then route the output signal from your audio interface to your speakers, headphones or PA system. The popping noise will not sound. I tested it several times.
If the only cable you have is a minijack male type then go to Radio Shack and get adapters. I had to get me an adapter that takes two RCA males and converts them to a female minijack type.
Good luck.

Cracking and popping noise Sound Blaster x-Fi Platinum Running on Windows 7 32 Bit

Hi everyone, I am using a x-fi platinum card and it simply wont work with Windows 7 Ultimate 32 Bit. I have been using both windows 7 public beta and release candidate for last 8 months. Let me give you my PC configuration.
Intel Pentium D 3.4GHz
2GB DDR2 Memory running in Dual Channel Mode
ATI Radeon HD 4670 Video Card With 52MB DDR3
It has a built in sound on mother board (Disabled at the moment)
With the above configuration I tried using my x-fi platinum on both Windows XP and Windows Vista, and it worked perfectly without any problem. When I upgraded to windows 7 beta for the first time with the creative beta driver for windows 7, I noticed that whenever there is any on screen activity, such as minimizing and maximizing windows, switching windows, scrolling, photo or webpage transition, etc. there are cracking and popping noises. And if there are continuous or too much activity on the screen at some times the sound card completely fails and unable to provide any sound. When I took the sound card out and enabled the on board audio chip (Realtek HD Audio), the sound was fine without any cracking or popping issue. I eventually upgraded to Windows 7 RC and also currently using the latest driver for windows 7 and I am still having the same problem. As a reasult I am being forced to use the on board realtek audio solution which provides really crappy sound compared to x-fi platinum.
It appears that the problem exists only when I try to run x-fi platinum on windows 7. I really hope there is a solution for this otherwise I will have to sell my beloved sound card which I have been using for at least 3 years on ebay and stick with low quality Realtek HD sound system.

Popping noise after export

So my song plays just fine in GarageBand, but when I export to iTunes, there are some popping noises that come in (very subtly) at the same parts in the song. Here are some troubleshooting things I've already checked:
1) It is not my speakers -- I've tried two different pairs of headphones, and another set of speakers.
2) I do not have the decibels amped in the GarageBand edit.
3) I've tried reducing the decibel levels to all negatives, and it still pops in the same spots.
4) I've tried exporting the song in all different formats, compressed and uncompressed.
Anyone know of something else that might work? Thanks!

Did you change your song's tempo after recording? If GB has to re-render a sound file, it often introduces artefacts.

FIOS router causing static and popping noises on computer audio

Hi, I'm a less than two week old FIOS internet user and am loving the speed and service but I have one problem. The FIOS router seems to be causing static popping noises my desktop computers audio that is connected to the FIOS router by the yellow Ethernet cable. Theses noises don't occur on any of the laptops connected to the router by the wireless or when I connect a laptop to the router via a Ethernet cable.
Ways I found to eliminate the noises temporary:
Restarting the desktop computer or shutting down then turning on the desktop computer.
Ways I found to eliminate the noises permanently
Turning off and unplugging the router.
Hooking up the FIOS router via the Ethernet cable to a laptop. I unfortunately do not have a wireless built into my desktop.
What I've tried and failed
First I thought it was the Ethernet cable, so I replaced it. The noises did not go away.
I thought it might be the headset I use which are connected to the computer by a usb port. Unplugging the headset and using earphones which are connect to the computer by the audio slot did not eliminate the noises.
Then I contacted Verizon, and they thought it might be a faulty router, so they sent me a new one. The noises unfortunately did not go away.
I then thought the noises might be occurring because the router was close to the computer. So I moved the router as far away as possible from the computer (its connect to the router by a Ethernet cable so it wasn't that far) but the noises didn't go away.
Notes & Points
The noises do not start the moment I turn on the router and computer, but a hour or two after.
I think I've narrowed the problem down to occurring only when the desktop computer is connected to the router by the Ethernet cable. Though replacing the Ethernet cable has not resolved the issue.
I also have found that location of the FIOS router also doesn't matter since the noises did not return even though the router was right up against the computer when I connected the FIOS router to my laptop.
I have Windows 7 Home Premium 64, 3.5 gigs of ram, and a dual 2.0 GHz processor.
So that sums up my problem. If you guys have any tips or ideas of how to fix my issue, it would be greatly appreciated.

Sounds like a shielding problem on the AUDIO cables or a grounding issue. PC sound systems are notorious for having lousy audio cables feeding (I regularly pickup the local FM station on my speakers).
Try replacing the audio cables with better quality shield cables and see if that helps.
Are the router, speakers, and PC all plugged into the same outlet? Are they all polarized plugs? If note, try flipping the power plug on the non-polarized connections.
The sound could be coming from interference INSIDE the PC itself ... the proximity of sound cables inside and the audio chipset to the ethernet chipset. You didn't indicate if the audio/ethernet are on the motherboard or seperate cards. If they are seperate cards, try relocating the cards furfher from one another inside the chassis and also look at the audio cable (particularly the analog cable that runs from the CD to the audio card to make sure it's not routed past or near the ethernet electronics.
How far distant is the router from the PC? If you pull the ethernet cable from the router (not turn if off, unplug the ethernet cable running to the PC), does it stop?

Final Cut 10.1.1 Export Issues & Popping Noise

I've been having some very strange problems that I've never heard of before in Final Cut. First off, I downloaded historical footage I needed for this edit from Youtube as .MP4's, cut them together with some audio, and had everything ready to go. Inside of Final Cut, play back was great. I then tried exporting, and I got the "The share operation "Master File" has failed. The operation could not be completed because an error occurred when creating frame 80 (error -1)." The frame number changed between frame 80 and frame 23, seemingly at random. I started out by Goggleing. I tried deleteing my render files, turning off background render, deleteing my preferences, making a new project and pasting everything in, duplicating the project, and more. Absolutely nothing worked. I then started the process of elimination, and deleted parts of by timeline to find the problem. As it turns out, I had to delete my two compound clips (both only audio) and put them in the timeline without a compound clip. It then finally exported, only to find that one of my clips had a ridiculous popping noise, exactly like the Final Cut 10.0 bug. I've tried changing my sample rate, converting the video, exporting the orginal clip's audio with Quicktime then syncing it with the clip in Final Cut, and even just adding an effect to see what happens. The popping still remains. Any ideas? I couldn't find anyone on the web with this problem that's back from the dead. Being able to use compund clips would make the edit a whole lot easier too. Thoughts?
Here's my computer specs, if they help:
2011 27' iMac
Quad core i7 processor with four virtual cores (8 cores total)
16 gigabytes of RAM
256 gigabyte SSD
2TB HDD (I've tried transfering the edit to both drives, no luck.)
At this point I'm ready to reinstall Final Cut, but I haven't done it before, and I don't know what it entails. I'd prefer not to lose prefernces, etc. In general, I'd rather not have to do that though.

Luis, just to add to my previous post, I just found a removal process online that is specifally for removal from Mavericks. Can you verify if this is the one to use over FCS Remover (which I think is for previous versions). Here is what I found:
In Finder, choose Applications from the Go menu.
Locate the Final Cut Pro application and drag it to the Trash.
In Finder, hold down the Option key and choose Library from the Go menu.
In the Library folder that opens, open the Application Support folder. Move the Final Cut Pro folder to the Trash.
Return to the Library folder and open the Caches folder. Move the "com.apple.FinalCut" folder to the Trash.
Return to the Library folder and open the Preferences folder. Move the following files to the Trash:
com.apple.FinalCut.LSSharedFileList.plist
com.apple.FinalCut.plist
com.apple.FinalCut.UserDestinations.plist
I just want to make sure so I don't have any problems with a fresh download from the Apple Store.
Thank you again!
