Sound output in macbook pro (speakers vs headphones)

Every time I plug in my headphones, the output from the speakers to the headphones does not happen immidiately, it takes about 3-5 seconds once the headphones are plugged in for the signal to switch from the speakers to come in through the headphones. Why is that and can that delay be changed?

That is because it has to execute a change in the routing and such, it "system world" all of my machines do the same thing. The speakers and headphone jack are not a paralleled signal path they are two seperate devices and need to switch over. (Think of the system as opening a micro app)
As far as I know there is no way to change this, it's just the way it is.
Hope that helps

Troubleshoot Sound output for Macbook Pro 2009

macbook pro 2009 Sound output choice does not drop down anything but "internal speakers" choice. HDMI cable streams video and no sound. Have swapped out HDMI and it recognizes no sound for either. I think it could be a faulty adaptor for HDMI cable connection? It used to work fine then it stopped working and gave me a planet screen on TV when video was playing fine on computer. I tried again after software updates and a new hard drive and now it streams the video but sound only comes out of internal speakers. Wondering if I could be missing something on my mac before I buy another adaptor.

Another option, if you need a multi-channel sound support is to use a Optical cable like -

The sound on my macbook pro does not work if I plug headphones in I can still hear but it will not project volume out loud and when I try to turn up the volume it is just greyed out what do I do ?

The sound on my macbook pro will not project anything if I plug in headphones I can hear but when I take them out and try and turn up the volue the speaker is grey and the bars under it are white with a no volume sign ( circle with a line through it) how do I fix this ?

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers
    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.
6. System Preferences > Sound> Sound Effects
    Play sound effects through:
   Select "Internal speakers" and then back to "Selected sound output device".

I am getting no sound on my macbook pro. The sound does not play when I plug in headphones either. I have tried making it louder quieter, restarting my computer, HELP!

There are many possible causes for this issue. Take each of the following steps that you haven't already tried.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. If your model has an audio-out (headphone) port, and anything is plugged in, unplug it before putting the system to sleep.
3. If you've installed something called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and reboot. You should do that even if the software is not causing the problem, because it's useless.
4. If you've installed an equalizer called "Boom" or anything similar, update or delete it and reboot.
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select the Output tab. If the Mute boxes are checked, uncheck them. Move the Volume sliders all the way to the right.
7. If a red light is coming from the audio-out port, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Reboot and test.
9. Boot in safe mode. Don't log in; just reboot as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
10. Reset the NVRAM.
11. Reset the SMC.
12. Reinstall OS X after backing up all data. For a possible shortcut, see this thread.
13. Make a "Genius" appointment at an Apple Store.

The sound on my macbook pro is not working

The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!

The sound on my Macbook Pro does not work.

The sound on my Macbook Pro does not work. When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done. I went into system preferences, but there aren't any options there that I can see to change it.

"Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
Au contraire. TS1574's title and affected products are thusly:
"Troubleshooting issues with no audio from built-in speakers on Macs
Products Affected Mac mini, MacBook, MacBook Pro, iMac"
As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
2. Remove any external audio devices from USB, firewire, etc.
3. Open Sys Prefs > Sound > Output
If Internal Speakers is listed, select it and test again.
If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
If mute is selected, unselect it.
If the volume slider is low, raise the volume.
If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
I hope it gets resolved for you. Good luck.

The Sound On My MacBook Pro Isn't Working

The sound on my MacBook Pro is usually fine, but today it didn't work. For example, I tried listening to music on iTunes and watch videos but the volume wouldn't work at all. When I go to turn up the volume, it seems to turn up ok, but when I try to put on some music, it doesn't work at all. I then tried using my brother's Apple headphones on my MacBook Pro, and then the sound worked normally. I really would like this fixed so if someone could help me that would be great, because I don't want to keep using my brother's headphones just to watch a video or listen to music. Thank you to anyone who helps!

Hey
I did a NVRAM reset, and nothing happened. The sound stayed the same. Whats an audio output port, where can you find it, and where can you find the red light? When I try turning up the volume, instead of turning it up a cross sign appears under the speaker, thus no volume turns up. The menu bar right at the top of the screen - the speaker icon is not black, but more a very light grey.
Thanks for helping though!

MacBook Pro Speakers have a 'start' click. How can I disable it?

Hello all,
It seems that my MacBook Pro Speakers make a 'start' noise, when they have to 'play' a sound from absolute silence. Why is that? This has become extremely annoying, especially when I get notifications from Adium every now and then. Any workaround on this?
Thank you in advance.

It is quit possible that one of your speakers has become defective. A had a similar issue with my previous MB, brought it to the Apple Store and the genius determined that i need to replace one of my speakers and sub.
If you are still covered, i would advise you to get it checked out.

Macbook pro speakers stopped working, earbuds fine

My macbook pro speakers stopped working, but the earbuds work fine. Tried restart and preferences. Volume icon is grayed out, except when earbuds are plugged in. What am I missing?

Look in the audio output port. If there is a red light, the internal switch is stuck. Insert the earphone jack a few times. Blow into the port as hard as you can. Use a toothpick or something similar and jiggle it inside the port. If no success, bring the MBP to the Apple store genius bar.
Ciao.
If there is no red light, try a PRAM reset:

I can't get sound on my MacBook Pro

I can't get any sound from my MacBook pro. I have checked setting and volume is at full sound

Have you gone to settings > sound to make sure your built-in speakers are selected? That would be my first guess for troubleshooting.

How do i stop the chiming sound on my macbook pro?

There's an annoying chiming sound on my Macbook Pro that goes off sporadically when I have the volume turned up and I have no idea how to turn it off. I'd like to make it go away. Any answers would be appreciated.
Thanks.

Check the iCal app to make sure you don't have a periodic event set up to go off every so often.
Or check the Date & Time preference pane in System Preferences to make sure the clock isn't set to chime on the hour.

Dust and debris in the Macbook Pro speakers

I've noticed that there is a small buildup of dust and debris inside the small holes of my Macbook Pro speakers. Can anyone recommend any ways of cleaning this debris out, such as removing the top cover, or using a suction device? Any help would be greatly appreciated.

Either blow out the dirt with a can of compressed air (but not too close), or use a small vacuum cleaner designed for computer use (anti static). I wouldn't remove the top cover unless you are certain you'll put it back exactly as it was so as not to void the warranty.
