Awful sound output threw audio jack on macbook

hi, i have a new issue with my macbook :
i can't use airtunes anymore because of the dropouts, so i use the internal speakers to listen to music.
the thing is when i use headphones, the sound is awfull : there are like audio cuts every second.
and whatever headphones i use (including the iphone ones).
has anyone experienced this ?

Internal speakers not shown in sound output, no audio jack red light

Hellooo!
So basically my internal speakers in my mid-2009 Macbook pro are not working. When i try and change the volume i am getting the greyed out speaker symbol. Strangely, when a pair of headphones are plugged into the audio port and set to 'audio input' the internal speakers show up in system prefs, and the sound start working! When the headphones are removed it reverts back to not working again. I'm not getting the red light in the audio port.
This must be a software problem as they physically work when headphones are plugged in and i can hear the chime on startup.
I have tried repairing disk permissions, resetting the PRAM/NVRAM, re-installing OSX and the whole toothpick in the audio port thing.
I dont really want to have to take it to apple but I dont have any options left. My mac is pretty old, so i dont feel it is worth spending loads of money on it should the motherboard need replacing or anything similarly costly.
Has anyone else had similar problems, or a solution?

Route sound output to microphone jack?

Hi,
I have a 5.1 Soundsystem I want to use.
My Notebook has 2 headphone jacks and one microphone jack.
Is it possible to route the sound so that micropone jack outputs front/center headphone1 gives front and headphone 2 gives rear with ALSA?
I already used the board search and found a thread that links to this page. But I did not really understand what's done in this .asoundrc file.

You will have to experiment with ttable entries, to see if it will work - see upmixing examples.

Routing Sound Output - M-Audio 1814

Hello,
Just got a Mac Book Pro and am using an M-Audio 1814 as my sound card. The 1814 is connected to my stereo via s/pdif, but I cannot for the life of me figure out how to change the output in the system preferences so sound from the web, itunes etc. comes through the s/pdif output rather than the analog channels.
Any ideas?
Thanks!

Problem solved...this was the answer for future folks in need:
In the FW 1814 control panel set the the Digital Port Selection to SPDIF
Set the SPDIF input port to the desired selection
Then go into you computers HD and go to Applications>utilities> Audio Midi Setup
Mske sure you are in the Audio Devices window and click configure speakers
Set left front to 5 and set right front to 6, then click apply down below

Is there a cable that works to hook up iPad to an older Bose sound dock without audio jack?

I want to be able to watch videos on my iPad while hooked up to my Bose sound dock, and from what I've read on various forums it seems that simply buying an extension cable is not the answer, unless the cable has all of the correct pins wired end-to-end. And I'm trying to find a store or site in Canada where I can get one.
Thanks for your help on this!

I'm not aware of one. it doesn't appear Bose has jumped on making products specifically for the iPad at this point.

Audio jack from laptop outputting louder sound on the Right

My laptop which is an HP ENVY 15 Notebook PC with Windows 8.1has been outputting louder sound from the audio jack louder on the right earpud/headphone side than the left (or the left side is softer than the right). The sound outputs normally from the build in speakers though.
The speaker properties on it has both sides balanced on the volume output. I have tried resetting the BIOS and deleting the sound card drivers from Device Manager in the Control Panel. Also I've tried deleting the driver, redownload a new one, turning off the laptop, take out the battery and drain the power, then start pressing Esc...F10...F5...and so on steps (for the people that will tell me to do this).
Is there any other solution (besides resetting the laptop completely)?

Hello @danielmc4102 ,
Welcome to the HP Forums!
It is an excellent place to find answers and information!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I see that when you connect your headphones that the audio is unbalanced, but when you are using the internal speakers it is fine.
When you connect your headphones have you gone into hardware and sound and configured the headset?
Here is a link to HP PCs - Resolving headphones and headset problems (Windows 8).
Have you tried different headsets or this headset in another computer and is the issue the same?

Boot Camp Windows 7 do not recognise wifi, ethernet, USB ports and has a scary red light in audio jack output!

Hi!
I have just tried to install Windows 7 x86 version on my MacBook Pro running Mountain Lion and a couple of strange things start appearing:
    1. On the Boot Camp Assistant first screen, I tried to download the drivers and after about 15min the system responding that the server did not responded.
    2. I went further and installed the Win7 without making the ISO as requested by the assistant and with no driver burned on a CD
    3. After installed the Win7 I noticed that it did not recognise the WIFI in my home nor any other in the area;
    4. There is a freaking RED LIGHT coming from my Audio jack output that I have never seen in my life... and that scares me!
    5. The USB ports does not works on Win7 side !
    6. The ethernet does not work, Win7 just don´t recognise it...
    7. There is no Boot Camp on Win7 side to be deployed...
Basically I will use Windows to run Quicken for Windows, but I can´t acces my backups on Dropbox because I do not have intercet access, and obviously I am not going to be able to back up new files.
Is there someone able to help me?
I have:Boot Camp 5.0.0 / Win7 Ultimate x86 / MacBook 2,5Ghz Intel Core i5 MID-2012 / Memories 4GB amd 500GB/ OS X 10.8.1 / Boot Camp partition with 50Gb for Windows.
I appreciate all help!

Did you make sure to install the Bootcamp utilities after installing Windows? They can be found in the boot disk/usb flash that Bootcamp creates (check for a folder called "Windows Support").These should enable sound/video/trackpad/etc.to work with full functionaliity under Windows (you may need to reboot after doing so). After installing them, you may also want to run Windows Update to make sure you get the latest drivers.
As far as the red light, many models of Macbook Pros are equipped with a digital Audio out. You can either use the standard analog 3.5mm Stereo jack (standard headphone connector), a 3.5mm miniSPDIF digital coax or miniTOSLINK digital optical cable (hence the red light). Windows may not know how to handle to audio out port until the proper drivers are installed and it may be enabling the digital signal by default. Installing the drivers mentioned above should set this back to normal operation.
hope this helps.
Toodles!

How can I change default audio / sound output or remove the displayport audio option?

I upgraded from Mavericks to Yosemite and while I don't have any of the number of issues that see to accompany that move, I've discovered a different one that is not necessarily related to it, but is irritating.
2014 Macbook Pro Retina
I use a thunderbolt to displayport (AKA just displayport) cable to attach a Dell monitor to my mac at the desk.
Prior to this update, the mac ignored the display as far as audio was concerned (the Dell does NOT have audio built in). But now it seems to think it does.
Moreover, it continually switches back to that Sound output in the preferences whenever I plug or unplug an audio source from the audio jack. This is Annoying!
Is there any way to either
1) set the default to prefer the internal speakers / headphones instead of the DP?
2) remove the Sound output for the DisplayPort connection (which is a false connection since the Dell doesn't actually have AUDIO)
Thanks much

I found the com.apple.audio.SystemSettings.plist and Com.apple.audio.DeviceSettings.plist, but can't make sense of either enough to feel confident in altering any entries there. here's the SystemSettings one that seems like it might have something you could change, but...

Audio out jack malfunction macbook pro 15-inch (late 2008)

The audio out jack on my MacBook Pro is functioning intermittently. I am sure this is a mechanical problem effecting the analog signal (no red light indicating digital output). I have checked the system prefs for sound-- output shows device connection and mute box is not checked. If I jiggle the plug I might eventually get a connection. Did a little research and the problem seems to be occurring in the 15-inch Unibody MBP from late 2008 (my machine) due to faulty design of the jack. Most sites do not recommend replacement of the jack due to the necessity of resoldering to the logic board. Some suggested inserting a piece of tinfoil to tighten up the loose jack but I am not comfortable with this. Any suggestions out there?

Resetting SMC could solve the problem.

And you need to install more RAM, I think.

No sound from audio jack and screen doesn't dim, using BootCamp 3.1 in Win7

I'm using BootCamp 3.1 in Windows 7 on a MacBook Pro (13-inch, Mid 2009)
When I plug in headphones I get no output sound; however, I do get sound from the main speakers (regardless of the headphones being connected or not). Side note, there is no red light coming from the audio jack.
Another problem that I'm having: when I try to dim the display, using either F1 or F2, or from the BootCamp Control Panel in the Dim tab, it doesn't dim.
I've saw in Apple's Support Download section that there is "Boot Camp Update for MacBook Pro (13-inch, Mid 2010) (Windows 64 bit)", but as you can see it's "Mid 2010" and not "Mid 2009".
However, for the sake of exhausting everything I can think of before posting here, I tried to download and install it. Only to get an error that states "The patch upgrade cannot be installed by the Windows Installer service because the program to be updated may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be updated exists on your computer and that you have the correct update patch."
Any suggestions?

NO SOUND output (except for start-up chime) on MacBook Pro

I've been looking all over the discussion boards but haven't been able to figure this one out.
Suddenly for no apparent reason I have no sound output. I've checked all the settings, repaired disk permissions, restarted, etc. with no effect. I DO get the start-up chime but then nothing. Also, I do NOT have a red light emitting from my adio out jack. F3, F4 and F5 show the volume icon changing on-screen but with no actual sound output. Switching to a speakers or earphones doesn't change it either.
The only thing I can think of is that my battery has been slowly dying and has just recently started to crap out when the battery life indicator shows more than 50% charge. For this reason the computer has lost power and suddenly shut down once or twice without having been properly shut down. But the loss of sound input did NOT happen directly after this.
Any suggestions?

I Finally figured it out...
For some reason, my audio setting got changed in my audio prefs:
System settings --> Audio
On the "Sound Effects" tab, it was set to "Internal Speakers", which explains why I was getting the startup chime, and alert sounds just fine.
However on the "Output" tab, it somehow got changed to "Sunflower" which causes the sound not to work. As soon as I changed it to "Internal Speakers" everything went back to normal.
Hope that helps!

After attaching the headset to the audio jack, i get sound from the laptop speaker

after attaching the headset to the audio jack, i get sound from the laptop speaker

This worked for me as well. Great find! I have gigabyte ep45-ud3r motherboard and I was getting all sound through external speakers except itunes was playing the sound out of the digital output instead of the speakers. I could see this when I went to control panel > hardware & sound > manage audio devices. I did the repair as described above and now I have sound in iTunes.
