Macbook pro retina sound buzzing

Just bought a brand new MacBook Pro Retina, 13-inch, Late 2013 yesterday. I absolutely love it, but I have a small problem. On certain itunes movies, I have noticed, when the sound is high, that it will creat a very annoying buzzing sound. Is it a problem with the mac or the movie? I don't no. If there are any solutions to this problem, I would be very grateful to here them!

I have a simular problem. It happens all the time with headphones in or if I play sound through the speakers, in fact it happens once the sound is up more than half way even if nothing is playing.

Does your MacBook Pro Retina speakers buzz?

I have the new MacBook Pro Retina, which I absolutely love. The only issue so far is that the speakers buzz sometimes. I've tried different equalizer settings, which helps somewhat. Has anyone else experienced a buzzing or distortion in their audio output? It almost sounds as though a speaker is blown.

This is what I think the problem with the MB Pro Retina speakers is...
Frequency Response is very good. The speakers sound great with distinct sounds across a wide range of frequencies. But it sounds horrible with low quality TV or movie recordings where a lot of mid range and low frequency sounds hit at the same time in a muddled mess. Volume Handling is simply horrible across the mid and lower frequencies. Many movies will buzz when there is a lot of speech, music and bass going on at the same time unless you lower the volume to 1~2 bars.
This is not a problem with the recording except that the MBP Retina speakers don't like them. Recordings and low quality compression DOES NOT BUZZ, period. They may be low definition, they may sound muddled, they may have cut offs from exceeding the allowed dyanmic range, but they do not buzz. If you play the same movie on external speakers they will not buzz. If I play the same movie on my Dell Adamo it does not buzz. Listening to the same section of the same source on my earphones produce zero buzzing.
I am not sure if the problem is with the speakers themselves of other elements within the MBP Retina vibrating in resonance. But it is definitely annoying. And it sounds like component speakers with improper or missing crossover components allowing frequencies the speakers cannot handle at decent volumes to contaminate the driver or attempting to use mid-bass speakers as sub-woofers -- they actually have the frequency response just grossly insufficient travel of the diaphrams and cannot handle any decent volume.
We may be able to figure out the problematic frequencies and do a narrow cut in volume on them if we have a graphic equalizer. Unfortunately, unlike Realtek and IDT drivers, the Cirrus Logic drivers do not offer an EQ. I am tempted to open the MBP Retina up and try to graft an adhoc crossover onto the four speakers in form of caps and inductors. Given the low wattage of the components the caps and inds will be pretty small. But haven't gotten around to it yet... and part of me don't want to rip the MBP apart.

MacBook Pro Retina sound stopped working unless I put in and remove my headphones

I have a MacBook Pro Retina and the audio only works if I plug in my headphones and then pull them out. I hear the ding when I turn the computer on but nothing else once it's booted. Does anyone else have this issue? I confirmed that my sound settings are correct.

If you see a red light in the audio output port, then the headphones will be receiving the audio signal. When you insert and pullout your headphones you are probably tripping an internal switch that was stuck and now enables the sound to come from the internal speakers. This is a normal solution to that problem, but really should not occur. A trip to the Apple store genius bar might be a good idea. You still must be within the warranty period.

MacBook Pro Retina Sound Issues

Hi folks,
I used my MacBook Pro Retina with no difficulties over the last 2 month,
but recently I have experienced some sound problems.
Often, when I just want to play a video on YouTube or listen to some
music, the sound stops for a blink of an eye or is crackling throughout the
song or video.
It sounds a bit like the soundcard is having difficulties to play back the
sound, but I don't think a normal iTunes Song is causing this.
I furthermore imagine, that some driver is not running properly or
the threads for audio output are disturbing each other.
But I have absolutely no clue, what the cause is.
Maybe someone else experienced the same.
I would be grateful for any help.
Ps: I have the MacBook Pro Retina Mid 2012 (2,6 GHZ; 16 GB RAM; 512 GB SSD) Version,
if this is any hint.

Im terrifyed right now. I just got home, sat down and plugged my headphones into my Mid 2012 MacBook Pro Retina to start producing some music. As fast as I adjusted the volume on the MB a loud noise was heard in the right ear. I played a song in iTunes to discover that the sound was slightly distorted and very noisy in the right ear while you could hear the music normally in the left ear. I switched between an additional pair of headphones and a pair of speakers but got the same result. I checked the preferences and rebooted the MB without any luck.
I have two theories why Im having this problem. Earlier today I plugged my computer into a soundcard via 1/8 RCA-cables, allowing me to play music through my schools monitors. The soundcard had Phantom Power enabled but I disabled it quickly when I realized. The cable I used was also a bit dodgy, it was noisy and didnt work properly. Could this malfunctioning cable or the fact that I Phantom-powered my MB have fried my AUDIO JACK?! I contacted my teacher but he said that this cant be the reason for my issue.
My other theory, and this is the one I beg to be the reason behind the problem, is that a software update caused the issue. A couple of hours ago I updated my MBs software. I dont remember what kind of update it was though, probably quite a few since I havent done it for a while. I read on some forums that people have had problems with the retina MB and the sound after certain updates. Could this be the reason?
Im frustrated, frightened and very eager to make some techno. Any help or tips would be eternally appreciated!
Thanks in advance!!

Macbook Pro Retina: Speaker Buzz?

I noticed recently that my speakers are buzzing in songs that's hard to make out but I'm sure it's there for sure. Is there any way to fix it or is this something I have to go in for inspection? .__.

If a PRAM reset does not solve the issue, the take advantage of your warranty and make an appointment at an Apple genius bar:

Macbook Pro Retina Display - Sound and video doesn't work at the same time.

I just bought a macbook pro retina display and tried to watch a movie by connecting my macbook pro via hdmi to my home theater receiver (Onkyo TX-SR309) and into my HDTV (Sony Bravia 42"). My problem is, i don't get sound from the speakers connected to the receiver.
When i disconnect the HDTV from the receiver (only the receiver is connected to the macbook pro), then sounds will comes out from the speaker.
Can somebody help me to fix this problem?

With the HDMI connected and the Onkyo powered on, open system preferences, go to the sound panel, and select the HDMI choice.

Macbook Pro Retina, HDMI Sound issues

When I connect my macbook pro retina to my SONY TV via HDMI the picture works but I can't get any sound. I went into the sound settings and selected SONY but it tells me the select a device has no output controls.

This happened to me the other day, with an LG TV. Although it's not en eegent solution, I found that unplugging the HDMI, turning the sound up on the laptop, then plugging it in again worked. Until Apple releases a fix for the OS, that's the only thing I've found to work.

My macbook pro retina F2 key makes a squeaking sound due to heat!?

Hello All,
My brand new Macbook Pro Retina's F2 key makes an awful squeaking sound when i press it.... The sound got even worse when the macbook ran hot and i had to presse the key for multiple times....... Now it seems like even my F3 key is slowly dying when my macbook is under heat stress and i am pressing it.
Does anyone else have this problem? Its really bothering cause its a brand new computer, its still practically warm from the production line..... I called apple and they told me to go to a service centre :-( but i need this machine for my work and a service centre takes the minimum of 10 work days to repair it.........
What can i do....
Kind Regards Cor.

Hi guys, i know exactly how you feel. The rmbp should be perfect, i mean common its a 2300++ system... After i posted the above i deceided to take it to the apple store and let them fix it. I must say they did a good job! I got my rmbp back within 3 days! I think thats very fast.
What they did is they replaced the top case, cause the keyboard and mousepad are fixed to it. Also the battery is so thats brand new as well.
Now everything seems to work properly, i tested every key and searched for scratchtes or any imperfections but all seems ok.
I can only give you 1 advice if your key squeaks, take it back it should be perfect! In my case the squeaking only got worse and i still think it has something to do with the heat of the rmbp cause it came when i was gaming and the macbook got really hot.

My apple macbook pro retina 15'' ME664 has problems with sound.Either there will be no sound at all or at startup there il be very scary and broken sound and afterwards still there would be no sound.Secondly , it does not start in one shot.atleast 2 to 3 times pressing power button for longer time starts it up and afterwards still there will be no sound. Please help

This morning i was not able to hear sound on my recently purchased macbookpro retina 15 inch model.My attempts to resolve this issue by going to system preferences and removing the mute box that was ticked as active. i had downloaded much earlier a mac version of logmein app and noticed that in the sound box noted above that there was a bar indicating that the default was now to logmein. i had never used this app. Why it started today, i have no idea. I moved the logmein application to trash and deleted the app , however it did not remove the default option which still blocked the sound.
Going to a macforum gave the tha anser that to remove the logmein app, it first had to be reinstalled a nd them use the uninstaller option ftrom the dropdown menu. for now that has resolved the failure to allow sound oputput.

MacBook Pro Retina 13" makes a scraping sound when waking up.

MacBook Pro Retina 13" 2,6 Ghz 128 Flash storage started to make a short, mechanical, scraping sound when waking up from sleep. The noise seems to come from the right hand corner next to the trackpad. Did this anybody deal with something like that?

There are no moving parts in your Mac, take it to an Apple Store and ask them.

Macbook Pro Retina - Weird sound when plug in adaptor

Hi,
I have had my Macbook Pro Retina 15inch now for about a year and a half and suddenly it's making a sound whenever I plug it in. It's like the sound of a hard drive, but it's in sync with when I scroll up and down. There's no sound whenever it's unplugged, it's very strange. Any ideas, could it be a faulty adaptor?
Thanks
Lewis

It is better to take the computer to the Apple store and have it checked out.
If this does not help, contact Apple.

Sounds in the display - Macbook pro Retina 15"

I had a problem on Macbook pro retina 15 "after 7 months of use. If you gently shake the laptop horizontally, then something starts to hang out in the display. If you press on the screen and shake - sound disappears! What could it be?? Tell me please.

Hi David. I don't have as modern a Macbook Pro as you, mine is a 2012 model, but perhaps I can help. I often find that my SD card will not load when I first insert it. I have to remove it and then put it into the slot again firmly.
You also haven't posted any information about the SD card. What size is it, do you know how it is formatted, has it worked in that same mac previously, where did it come from, does it currently work in another device (such as your camera)? This sort of information will help to narrow down the problem.
If you post some more information I'm sure people will try to help you. In the meantime, if you look at your post again you should see "More Like This" at the bottom of the page and you may find an answer in some of those related posts.
Hope that helps.

Odd alert sound from Macbook Pro Retina

Hi, my 13-in MacBook Pro Retina is late 2013 version installed with OS X Mavericks 10.9.4.
Recently, every now and then there will be a "ding" tone that sounds.
I have checked. I do not have any alerts on nor is it the incoming email alert.
I also could not find this sound under the sound alerts menu.
Anyone can be of help?

sorry to hear about your problems. Try running Audio MIDI, see what's it's set it for both the line out/digital out. Holding down the Alt Key (next to the space bar) gets you a list of all the input and output devices on your macbook pro. Also, see if accessibility is turned on under system preferences. Other than that, I can't say. if you have wifi problems, see if there's an update for it (airport?) or see if you can change Wi-ifi channels on your printer
well, I tried anyways

NEW MacBook Pro Retina cracking sound problem

I recently bought a MacBook Pro Retina after using a MacBook Pro for a year. From Day One my MacBook Pro Retina makes a cracking sound from the body on the right side. not acceptable from such a expensive machine. Apple would not replace it! Now I don't know what to expect, but I never expected this. Laptops worth 400bucks are not this cracky. After browsing through i see im not the only one with this problem. The local apple service center said they have checked it everything is fine and it is not damaged, it was a manufacturers defect. Why should I be the victim here?

Resetting the NVRAM/PRAM didn't work. The crackling sound is especially bad around the 4:00 mark in the following Killzone Shadow Fall preview:
http://www.engadget.com/2013/02/20/watch-the-ps4s-killzone-shadow-fall-shared-di rect-from-the-con/
Several songs in the iTunes store, when previewing, also have the same crackling issue.
I'm just glad it's not crackling for every single video or song, at the very least.
