MacBook :: Horrible Noise Emitting From Pro Speakers / Fix It?
Jan 11, 2010
I recently got a brand new 17' unibody MacBook Pro. Although it was brand new, there have been a flare ups. The last time I had the problem, (note: it is always while watching a YouTube video) this is what I captured before quickly closing the window. http://grab.by/1Gjt
That was New Years day. The first time I experienced this problem, I got nothing on the YouTube player and while skipping throughout the video to get it to stream, a noise that can't even be explained screamed out of the computers speakers. Today, I just had the same problem. I have no clue what it is except that I do know it comes from the speakers. Could anyone elaborate on if something similar has happened to you?

I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.

I have an Imac which used to emit sound from my desktop speakers. Now they've stopped. I've tried Iceclean, turning off bluetooth, and running disk utility repair. All of which hasn't solved the problem. I tried the speakers with my laptop and they work fine. So I tried a different set of speakers with my Imac thinking it might be the speakers, but they work fine with the laptop. The speakers are connected into the headphone jack. In the sound pane, output source does not show the connected speakers. When the jack is removed from the headphone connection sound is heard from the built in speakers from the Imac. I have the latest IOS software installed.

Yeah, so this morning I woke up and awoke my iMac from sleep only to have it make a horrible clicking noise multiple times and stay frozen on the desktop screen. I restarted it and made it spit out my Lord of the Rings DVD, held down the option key and brought it to the boot menu. Started it up from there and it is running fine, no clicking.
Should I be concerned about that horrible click?

I'm connecting my mbp to my new lcd sony bravia via dvi to hdmi lead and then connecting the sound via headphone jack to tv's 2 x phono, however i'm getting lots of audio noise bleeding through tv speakers underneath the main audio feed, i'm certain that its not a dodgy lead as iv'e tried 3 of them, however if i unplug the dvi lead the noise goes away, is it possible that the hdmi input is conflicting with the phono connection somehow.

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?

I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?

Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.

I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?

Just set up a new Mac Pro (8-core) and plugged in my old M-Audio powered speakers (about 10yrs old but still going strong!). I use a mini-jack splitter cable that outputs stereo RCA to the speakers, plugged into the speaker port on the nMP. There is a constant, low hum coming out of one of the speakers; it sounds a little like CPU noise and it is NOT affected by volume settings from the Mac or the speaker knob. It's the right-side speaker which is unpowered, connected to the left unit via speaker wire (the left unit has the power switch and audio inputs and is not affected.)
I've tried moving the speaker wire up and away from power cables (two Dell monitors directly next to the speakers) but that doesn't work; it doesn't sound quite like a DC hum anyway though. The speakers aren't heavily shielded (they usually pick up interference from an iPhone placed too close) so maybe it's always going to be an issue. I used to have them plugged into a 2006 Mac Pro via an analog mixer which I've removed from the chain.

I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.
I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.
Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.

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.

I just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.

I have a first generation macbook pro and lately the fan has been making some horrible noises. I opened it up and blew some of the dust off. My fans are running at about 3700 rpms and my cpu temp is around 60 C. Is this problem definitely one of the fans? My computer sounds like it wants to explode. I've attached a sound file of it.

Let me start by saying I just bought a brand new, less than a week ago, (from the Apple Store) 17" Santa Rosa MBP with the hi res screen (matte), 160GB 7200 RPM HD, 2.4Ghz CPU and the 256MB 8600 GT. For some more background I am a system administrator and a PC tech so I know what I'm doing with computers (most of the time anyway ). Anyhow, after getting my MBP and installing Vista on it via bootcamp and thoroughly enjoying the dual booting, I notice the thing runs hot. Ok, I do some google'ing and find the various thermal paste horror stories floating around. In windows (I've been spending more time in windows since I got it) I notice that it is IDLING at ~ 53-60C!!! I think perhaps this is not right, something may be wrong with the temp monitor software I use? Well, I use several, one of which is Intel softare called Intel Thermal Analysis Tool that monitors the DTS (Digital Thermal Sensor) in each core, it also will load the pants out of an Intel CPU - ~ 20% higher load than Intel's specified TDC. So for living with the heat for almost a week I decide I must bust the machine open, remove the logic board (mother board for you non apple folk) and see what kind of thermal paste job is in there.
Let me say that removing the logic board from these machines IS NOT FOR THE FAINT OF HEART!!! It scared the #@#$%$ out of me a few times! I took my time and marked where every last screw went and every cable, even the yellow tape. Once I had the board out and turned it over (the CPU, NB and GPU face DOWN so they can't be seen unless you remove the logic board) the sight was HORRIFIC!!! In my professional opinion they used about 40x too much paste, yes I said FORTY TIMES! All thermal paste is supposed to do is fill the micro groves and pits in the heatsink so VERY LITTLE IS NEEDED! Too much is worse than none. Anyhow, I'm sure you want pics so here they are. Oh, and my idle and LOAD temps dropped by ALMOST 20C!!!
Shame on whoever is assembling these machines as the average user will NEVER fix this and would perhaps think 'this is just how hot it is supposed to run'. I would demand Apple fix this, I would show them pictures etc, etc.
Oh the HORROR!
Now the heat pipe cooling system before:
Here is a CLEAN logic board - From left to right: GPU, North Bridge, CPU:
Proper paste applied - I have some special diamond dust thermal paste that is VERY durable so I used it - I have seen others apply the paste to the chips AND to the heat sinks, THIS IS BAD, VERY BAD!!! ONLY APPLY TO CHIPS.
And finally the cleaned heat pipe cooler:

so my brand new 13" macbook air arrived last tuesday. over the last few days i've noticed that i only get 2-3 hours of battery life even with the screen brightness nearly all the way down. right now, i have 79% battery life remaining and it only says 2 hours 24 min left. I've only used it for about 30 minutes this morning and it was fully charged. i'm about ready to return it, this is extremely disappointing. anyone else having this issue???

I have iTunes 10.6.1 (7) an Airport Extream Version 6.0 Airport Utility (600.92) That I use with two airport express stations, an Apple TV 2nd Generation with latest software up date. Also have Ipad 3rd Generation and two I phone 4's. Issue: After installing the latest Airport Utility software update I'm unable to connect to my remote speakers in iTunes. The speakers are visible in the pop up menu but iTunes times out when trying to connect. If I use remote to select Apple TV and then via Apple TV select my Computers Library I'm able to play music on the Apple TV / Home Speakers... but still not the Airport Express Stations.
When using remote on the iPhone or iPad the speakers are visible as well but I'm unable to select them... iTunes times out. I can steam music from that is on my iPhone or iPad to each individual speaker, but multiple speaker control is not available and the music from my library is not available. I believe the problem is in the Airplay feature of iTunes and I believe the problems arise when you install the latest version of Airport Utility. You can play on remote speakers, only one at a time, and only if you have the music on a stand alone device (iPhone or iPad)... in summary, bypass iTunes and you can be successful... marginally successful.

that cool majestic sound is unworthy of the internal speaker.
My standard speakers play sound, but I've not gotten the power-up noise to go through them.
Do I have to use the fiber optic connections to get this sound routed?
Or is it wired into the main machine's speaker only?

My Early 2009 MacPro4,1 is emitting regular repeating tones from the speaker at about 1202 am every night. I have no alarms set. I can't stop these tones unless I shut down. The computer is set to not sleep.

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.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

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?

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.

Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was
in the other room.Is my PISMO dying?
(400 mhz pismo G3 500 sdram, osx-10.39, no os-9 or Classic, new 80g HD)

Sometimes (about one-fifth of the time) when I do a screen capture (using Command-Shift-4) there is a horrible loud cracking in place of the camera clicking sound. I have a pair of Yamaha speakers which are about nine years old but they work fine otherwise, no static, play iTunes great, etc.
Is there a setting I can change that would obviate this from happening? It's getting on my nerves because I'm starting to expect it each time, even though it's the exception rather than the rule. Or does it mean my speakers need to be replaced? I don't do anything musically-intensive on my iMac so I can change settings, but I would like to keep a decent basic level of stereo output.
I'm using a first-generation 1.8GHz 20" iMac with 10.4.11, but will probably upgrade to Leopard sometime this summer.

I've been having trouble calibrating my display on my 2010 Macbook Pro with Spyder3Pro properly. The calibrated profile is much warmer unless looked perfectly straight on, which is impossible, and when the screen is tilted down it becomes a deep yellow. I've tried different ambient lighting sources and screen brightness however none of the profiles look good. Has anyone been able to properly calibrate their 2010 Macbook Pro's screen with a Spyder3Pro?
