Sound on mac book pro
the sound output sound on my computer is shut off and the headphone adapter outlet is lit up red how can i fix this?
i have already checked system preferences but its told me i should take my computer in. also, every time i open system preferences folder to sound blue tooth pops up and says "continue using headset"
Plug in and remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.

Hi younesfromsouth pasadena,
If you are having issues connecting an external display to your MacBook Pro, but the same display and adapter appear to be working fine with another similar computer, you may find the troubleshooting steps outlined in the following article helpful:

Headphone / Sound Issues Mac Book Pro
Sometimes when I unplug or plug in my headphones the sound stops working completely on my Mac Book Pro.
It only starts working again when I restart.
When I restart it sometimes but not always comes up with the message that the iTunes volume is right down. Even though it wasn't when I pressed restart.You can expect the sound to be interrupted in some cases, especially if you're using a longer cable. Usually, if you wait a while, the sound will return when your MBP detect the signal. You shouldn't have to wait for a reboot to fix things.
What's happening is that your MBP is trying analyze whether to use the input or output. It seems it's taking too long, Go to System Preferences/Sound/Output; "Headphones" should be listed when your phones are attached. For "Input," make sure it's set to "Internal Microphone."
Or, as a test, plug in a pair of earbuds instead of a headphone.
Post with your results. -
I have mid 2009 Mac Book Pro running 10.9.1. The hdmi mini port no longer supports sound on the Sony TV. This is apparently a change. It no longer shows as an option in system preferences/sound.Any ideas?
The 2009's didn't support sound on HDMI. That came in 2010. Are you sure it ever worked?

Up grade now no sound on my mac book pro
I recently upgraded to mountain lion on my mac book pro 2009 and now I have no sound. Not sure how to fix it. The sound symbol is greyed out. When I select the increase sound button it has a international no symbol. My note book specks are listed below. I'm not sure if my computer meets the requirements of Montain Lion.
Hardware Overview:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,3
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number of Processors: 1
Total Number of Cores: 2
L2 Cache: 6 MB
Memory: 4 GB
Bus Speed: 1.07 GHz

Hardware UUID: 3523E80F-4FCA-5937-A329-9E230535C1F5
Sudden Motion Sensor:
State: EnabledI tried one last thing before I did this. I simply shut down my laptop and then restarted and the sound now works. My laptop was only rebooted after the install. The reboot was the second cold start since I installed Mountain Lion. I usually only put it in the sleep mode. I will continue to explore mountain lion and try these fixes if I have any more problems with the sound. Thanks a lot for the help.

I just bought 15' Mac book pro. as i work a lot on Garageband. I even downloaded all the drummers and loops to update the new Garageband 10.0.1
now my problem is that all my past work which i did on older version on GB, has missing sounds in it. so here are my questions
1. DO i have to install JAMPACKS on my new Macbook pro?
2. Are JAMPACKS still compatable with the new GB?
3. There is an UPDATE on the new GB on Appstore and once i click it, it goes to billing no detail is provided what this update is for so help!

See: This document explains what the in-App purchase is about.
Expanding GarageBand for Mac (v10.0) content with an in-app purchase
Do you still have your old Mac?
How did you migrate from the old Mac to the new Mac? Did you transfer your old software and documents using Setup Assistant? Then your old GarageBand '11 version should have been migrated, and all your instruments.
if you did not migrate GarageBand '11, copy your old Instruments Library and Loop Library over from the old mac. Copy the following folders to a thumbsdrive and merge the missing dontents into the corresponding folders on your new mac: (from the system library - the top level library folder on your Macintosh HD):
/Library/Application Support/GarageBand/
/Library/Audio/Apple Loops/
And if you would like to continue to use GarageBand '11 for access to missing features, copy also /Applications/GarageBand over, but to a subfolder of Applications. I recommend, to install the old GarageBand as well. It can be used in parallel to GB 10.0, and will come in handy, if your old projects are having problems.

The JamPacks are nice to have, a terrific collection of instruments and loops, but if you did not have them previously, that will not help with your missing instruments. You can instll them by buying Mainstage 3. They work well with GarageBand 10.0

My sound is not working anymore on my mac book pro
My sound on my mac book pro is not working at all anymore. I used it in the morning and it worked just fine and i came back at night and my sound was gone. I checked my output settings, raised the volume up all the way, made sure that i wasn't on mute, everything... Even when i plug my headphones in it doesnt work...
Any ideas???Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
Highlight Internal Speakers / Headphones
Make sure that Mute is not enabled.
2. Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
Audio Devices window
Side Bar
Click the Built-in Output.
Under Mute any of the boxes checked? If so, uncheck it. -
I am getting no signal to my dj mixer using m-audio firewire audiophile sound card connected to my mac book pro using Traktor Dj software can anyone help?
The firewire port reads the dj software and I can hear music playing through the sound card when I plug my headphones into it but there is no signal to the hardware (my dj mixer).
I have reset the firewire by turning off my mac book pro for a few hours and can see the sound card device in the fire wire section after clicking on the apple icon on the top left corner of my mac.
My dj mixer works on another mac computer with the same soundcard and different firewire cable.
Hope someone can help
Thanks
Waynekmiddlet88,
yes, it could be due to nearly anything listed in your kernel extensions, startup items, launch daemons, launch agents, or user items above. Please check all of your installed third-party software to make sure that the versions which are installed on your MacBook Pro are compatible with Mavericks; uninstall every software package which isn’t Mavericks-compatible. After you’ve done that, boot into Safe mode, and see if you still get the beach ball of doom there. If it doesn’t appear there, restart normally and see if it appears then. -
ive got a mac book pro i bought the lead to connect to the tv but is there a lead for the sound to come out of the tv and not the laptop?
Depends which Macbook Pro, depends what cable you have. MBPs from 2010 onwards can transmit audio through their Displayport connectors if you have an HDMI input on your TV and an adaptor which also transmits audio. Not all Displayport-HDMI adaptors do this. If you're trying a VGA input on your TV, that will not carry audio.
If your MBP is older than 2010, you will need to use a separate audio cable to connect from your computer's 3.5" mini audio connector to the appropriate audio input on your TV.

Go to sounds in system pref and select outputs. When the hdmi cable is plug into the tv it will show as an option under output. Just select that option.

On my mac-book pro the sound isnt working after I have installed OSX Mavericks, should I take it to be repaired, or can I do something on System Preferences?
In addition to checking system preferences/sound/output and selecting built in if that does not work, make sure volume is up and mute not checked.
You can try the following, Take a set of headphones and plug theim in and out several times (there is a micro switch that sometimes gets stuck)
Go to applications>utilities>Audio MIDI set up, see if you can select built in there, make sure volume is uo mute not checked.
Try a NVRAM/PRAM reset:
Power off, power back on holding the following keys OPTION + COMMAND + P + R
Continue to hold these keys till you hear the start chime 2 times, then release,reboot -

Install the required Windows drivers: Boot Camp Support Software 5.0.5033. Download this link preferably from Windows. Otherwise, download onto a FAT formatted USB disk from which you can copy to your Windows system.
