MacBook Pro :: A Single POP Sound From Left Speaker After System Heavy Load?
Apr 14, 2012
I bought Brand New Macbook pro 15" Late 2011 Ci7, this is incredible machine. But a month past and i started to notice a very strange behavior:Â When i using mac for resource "Eating" application or processes my computer starts to Heat-this is normal.
When i close all the apps here starts interesting) I have Istat installed, so i can see what temps are in my system. Computer is cooling, and when cpu reaches 50-55 degrees (Celsium, from 80 degrees, because of heavy load) ,my left speaker produces a single loud pop sound. (like something turning of may be)
Info:
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.3)
Over the past few months or so, I've been noticing a sound, much like a buzzing, coming from the left speaker area of my computer. It seems to be near the area where I plug in the charger. The sound is not terribly loud, but when it's quiet in my surroundings, it becomes quite evident. I'm not talking about an audio-related issue, but I am just unsure as to what may be causing the sounds and whether or not I should be worried.
i feel like i hear more from the left side of my mbp then the right. either that or my right ear is clogged with tons of nasty stuff......ive picked my ear (sorry for TMI) but its not working, so im pretty sure i hear more out of the left speaker. is this normal? i read something before saying theirs a "left speaker biased" or w/e
How many new macbook pro owners are hearing the macbook pro whine sound coming from the left near the speaker? is this normal? its getting very annoying. it stops for a min when i open an app or click or scroll.
Since updating the Windows 7 drivers with the Snow Leopard BootCamp version 3 I've noticed strange sound distortions coming from the left speaker of my iMac. This seems to be a driver issue because both under OSX as well with older drivers which came with Windows 7 RC1 the left speaker functions properly.
My iMac, which was new Christmas 2011, has developed a strange fault. If the computer is left idle for any length of time, I then find that there is no sound and the speaker symbol at the top of the screen has disappeared. Sound is only regained by rebooting.
I have a 2.1 Logitech Z4 setup, and the sound is only coming out of the left speaker. I have checked the wires, they are fine, and both speakers do work - but it could be the socket that's the problem. It's plugged into the line-in socket, I have put the output in System Preferences to Headphones, and everything is inserted correctly.
What do I do?
EDIT: My sound system is plugged into the headphones jack. I have tried putting headphones into the headphone jack and the sound also only comes out of the left earbud.
I noticed my Macbook White (late 2009 model) right speaker is slightly louder than the left one. I have checked the sound balance on my sound setting and its set to balance. Some things I have noticed when playing with the settings. When i shift the balance to the left, there's sound on the right when it's not supposed to. Then when I shift to the right, the left speaker is quiet. This problem seems to happened on older Macbooks - [URL].
I came across some youtube video with dual-language audio; ie. one language on the left channel and another language on the right channel. The Output page under Sound preference does not have the left/right balance control, probably due to the mono speaker in MBA. If I connect to an external speakers, or headphones, then the balance control re-appears. Is there a way to get around this problem, if I still want to use the build in mono-speaker?
My recently bought Logitech G5 'Gaming' mouse is no doubt a fantastic mouse. But everytime the CPU (Late 06 MBP) is doing something intensive, even if it's just one of the cores. When the mouse is moved, the pointer will skip to a random spot a few inches away on the screen. This happens over random intervals (from 2+ seconds).
Sure it's not so bad when I'm firing up VMWare and it skips around because response time isn't vital. But i'm playing games with it, and well, in WoW that means you run off cliffs and miss the potion, and becomes a major PITA.
I know the first version of the G5 (the rust coloured one) had similar problems. But apparently the new blue one (the one in question) is fine. The surface I'm using it on is a heavy sheet of cardboard (backside of a notebook).
Anyone else have this problem? And what does logitech do in these cases? I rang up tech support and got hung up on. Or do I need to go to the guy I bought it from?
EDIT: after running 'yes > /dev/null', it might not be totally CPU related, maybe the GPU has something to do with it. In any case, I'll be playing in another account to see if the problem arises there.
The tower speaker just doesn't cut it and I want to hook up my 5.1 Locitech speaker system. I couldn't find any Mac sound cards on newegg and am having trouble finding results anywhere else. What card is recommended by most Mac Pro users? My professions isn't in audio so it doesn't have to be perfect, just something to play games, music, and movies.
I have had my new pro since christmas, and it has been incredible. however i noticed from day one that periodically i get this buzzing noise coming from the left speaker - closest to the screen. is it the hard drive? what is it... and is it normal? sometimes if i tap the speaker area (next to the magsafe) it goes away.. and other times its pretty loud. i do NOT have applecare. should I purchase that as well.
i was playing Diablo3 when i suddenly experienced heavy, unusual lag. I tried to reboot to see if that could even things out. No success. It took longer then usual to boot up, and when i finally reached the login-windows asking for password, it wouldent react to my typing and clicking for about 5 minutes. I could move around the mouse and the keyboard did get signal (it un-dimmed the scren when i pushed any key after letting it dim over time).Â
Then i tried to do a clean install of OS X Snow Leopard (formating the drive and then install). After longer then usual,reached the "choose your language" window. This window too had extreem long respond-time. I managed to start the installation but it stopped at 33minutes remaining, giving me the "Install Failed" window. this told me "Mac OS X could not be installed on your computer. The installer could not copy the necessary support fies. Click restart to restart your computer and try again.". I tried it again but it gave me the same result.Â
it made me believe the hardware was the problem. First i swapped the Optical Drive with an older vrsion MacBook (2008), this gave me the same install-problem (stopped at 33mins left)Â Then i swapped HDD with the older MacBook. It managed to boot and start "normally" with exactly the same problems as the original HDD. The first thing that gets to my mind is that something might be fried inside the computer.Â
I restored the original HDD with TimeMachine (needless to say i still got the problem). I'm in the middle of my exam-papers, so its reaelly annoying its happening now.I also tried installing OS X SL using an external HDD with an image of the installer disk made in disk utilities, but this only gives me "kernel error" during booting (the annoying dimmed screen with a black box in the middle telling you to restart).Â
Today i took a look in the Activity Monitor and it shows the CPU acting strange, spending 100-120% on kernel_task ALL the time (see added picture).Is something wrong with the CPU? Is it possible to fry only one core in a CPU leaving the others intact?I have different components available for change as long as they match each other (Macbook pro 2010 and MacBook 2008). Â
I was wondering if there was any way to troubleshoot the sound error from my home or will it need to be taken in for service? Is it the same price at Best Buy as it is the Apple Store?
Ok so my iMac g3 has a left speaker that doesn't work. The right one works fine and when I turn the volume up the left speaker kind of buzzes. Is it even worth replacing the internal speaker? (IIRC it looks pretty difficult)
I am heading a strange sound from my speaker, sounds like an application is causing it. I check the logs and I dont see any errors. a good method of tracking down the error? Is there a log file for system sounds or do I have to kill each application one by one and wait 2-3 mins between application kills to see if the sound comes back.
today I noticed that my speakers have a buzz/hum sound coming from them. The speakers I have are the Logitech X-240 with a subwoofer. The speakers are hooked up to the subwoofer, which is hooked up to a sound base that is connected to my MacBook.
My sound works fine at first, then I plug in my headphones and sound still works but when I pull out my headphones I lose sound in headphones and speakers on my 13" MacBook Pro. Only a reboot (as far as I know) fixes it.

I woke up this morning and tried to watch a linked video on a webpage. I saw the video, but there was no sound (this had not been a problem the evening before). I am using USB soundsticks, so I checked to make sure that they were plugged in, and they were. I opened iTunes and sound came through the Soundsticks; I switched to the internal speaker and it worked there as well. When I tried the same with another embedded video, however, I only got sound from the internal speaker.
Has anyone had a similar problem or does anyone know how to fix this?
For the last two weeks I have been using my new macbook pro. I'm a bit concerned about the sound quality that i get from the speakers. According to specs it has a subwoofer (I know you can't expect much from a tiny laptop) but I still can't really hear any base/low frequencies and it sounds like a tiny cheap transistor radio . The volume is pretty high, I can listen to youtube etc, but its really almost only trebble. I expected a bit more. Is it normal for those macs or is it just mine?
I had Sony Vaio before and then Dell XPS 1530. Sony had way better speakers and even Dell seems to sound a bit less can-like/tiny...
Whenever my MacBook's sound is on mute and the computer wants to play a sound, the speaker has this little click noise.
For example, I mute the sound and go to trash a file. It trashes normally, but at the beginning, the speakers click (almost like they want to play that empty trash noise, but cannot because it is mute).
After I upgraded OS X Yosemite on my Macbook Pro that seems I can't play sound with my external speaker, I hope that this issue is only Bug not impact with my hardware.
I just purchased a Bose SoundLink Mini bluetooth speaker. It pairs up and connects fine with both my iPad Mini and Macbook Pro. The sound quality is excellent on playback from iTunes on the iPad Mini, however when I connect with the Macbook Pro....I am getting terrible popping and cracking sounds. I am using Lion 10.7.5 on the Macbook Pro. Wondering if it must be some issue with the operating system since I DON'T have the problem when I play audio from the iPad Mini.

I have been having this issue forever and want to do something about it now. Whenever the sound is mute on my notebook, and there should be sound playing (Ex.: Startup Chime), instead I get a LOUD pop noise. I understand the whole thing with the sound chip powering down to save battery life, but that requires the speakers to be un-muted. In my case, they are mute, and never get un-muted. What do you guys think. Logic Board/Speaker System Replacement?

It's only today that I noticed my MacBook's right speaker is considerably louder than the one on the left. I opened Sound panel in System Preferences to see if the balance was off, but it was set at dead center. Then, I dragged the balance slider all the way to the left to see if the sound coming from the left speaker was okay at all. Well, it sure isn't. Very muffled, muddy sound. No highs at all. Dragging the slider to the right side reveals a very different sound texture. Very crisp, as it should be. Really weird. Anybody else experiencing this odd speaker behaviour?
I googled for this problem and found this thread, right here on Mac Forums. It's a thread for the MacBook Pros, though. The people with a MacBook Pro think it's because there's a subwoofer on the right side. Well, the MacBook doesn't have a subwoofer, so it can't be that. Any ideas? Is it repair time?
By the way, I have a late 2008 unibody MacBook, the 2,4GHz model.
