Intermittent sound problems on MacBook Pro.

I have for the last few months had this intemittent sound problem. The speaker greys out and the sound 'jumps' between speaker and internal sound. The little red light inside the headphone port comes on. This could last for a few minutes and then everything is fine again. It happens when I play DVD's as well. The sound goes and the DVD practically stops playing or the picture is slowed down and jerky. Usually after ejecting the DVD and inserting it again it sorts the problem out. It used to not happen very often but for the last two days it has happened at least 5 times. It happened during a presentation once and I need this to work. Any advice please. I am worried it could be a hardware issue.

Sound problem on MacBook Pro with XP

Hi all...
When I have headphones or an audio cable plugged into my MacBook Pro running XP and BootCamp 2.1, the sound will occasionally distort digitally for a second or two, then the sound will cut out, go through the internal speakers, then go back through the cable an a message will pop up in the tray telling me I just plugged something into the audio jack. This happens about once every five minutes or so.
Is that a driver issue, is it the headphone jack, or is it the cable?
Any ideas welcome!
Thanks,
marcintouch

Hi guys,
I just updated bootcamp few hours ago with xp pro 32 bit on 2.2ghz macbook
and as I tried to use the audio jack, the sound never goes through my earphones but went to the internal speakers instead.
So I googled the problem and realized it should be the driver's problem
I've tried to repair with the leopard cd to fix the problem, but since it's now 2.1 based so it didn't work
Here's what I did to roll back to bootcamp 2.0 driver without touching other 2.1 udpates
Go to start->control panel->system, a small window should now pop out->choose Hardware tab-> Click on Device Manager button on the top, another window should now pop out too-> roll down to the section saying 'Sound, video and game controllers' and expand the list by clicking the '+' symbol on its left->you should now see a list with a several names, one of them should say 'Realtek High Definition Audio', when you see it, right click on it-> after right clicking, a drop down list should appear, click on uninstall-> it should now be gone from your list since it's now uninstalled, at this point, click on the button on the top of this window where it's under 'Help' near middle left with a symbol looks like it's a computer with a magnifying glass, it's next to a button with a big question mark. The button will scan any hardware that has no driver on your computer, of course including your just uninstalled Audio device. Now, DON'T CLOSE Device Manager window(still need it), but grab your leopard 10.5 disk and insert to the optical drive, when it prompts to ask you what to do, you click 'Cancel'. After that, go back to Device Manager window, you should now see big yellow question mark popped out from no where saying it's the Audio Device, right click on that one and choose update driver. Another window should now pop out asking you what to do, choose 'No, not now' then click on 'Next'. Now, here you should see a several way to update the driver, choose the 'automatically (Recommended)' one then click on 'Next', it should now run by itself through optical drive so just wait for now. Afterwards, it might say cannot update but make sure in Device Manager the 'Realtek High Definition Audio' appear properly under the sound list (that's what happened to mine) now it should work, or else just use the Repair function of leopard cd if this ultimately fails
*This is my personal experience, it worked for my case but I am not responsible to ensure it will work for other cases as well.*
Please do let me know if it works after you try it though
Thanks.

Sound problem on Macbook Pro (Windows 7)

I have installed windows7 on late 2011 macbook pro but sound not working.
I have used bootcamp for installation.
Also the audio jack emitting red light.
Please help

Assuming you are running Lion or Mountain Lion, did you download the Windows Support software when you ran Bootcamp Assistant? Did you save the Windows Support software per the instructions you printed from within Bootcamp Assistant? Did you install the Windows Support Software from within Windows per the instructions in Bootcamp Assistant?
If you are running Snow Leopard the Windows Support Software is not downloaed it is on your Snow Leopard install disk.

Sound problem with macbook pro! help please

hi guys!!
my mac sound is not working also the headphones however if i plug the hdmi cable it works on my tv !!!!! I think it is a hardware problem!!
what do you think guys !!!!

Hi a,
Have you checked the settings in System Preferences > Sound?
There is a switch inside the audio jack that may be stuck. Try gently inserting an audio plug, gently wiggling it, and then removing the audio plug.
See if this discussion helps: https://discussions.apple.com/message/16201033#16201033

I can hear a loud 'CD spinning/fan like' sound from my MacBook Pro intermittently. Definitely not the audio as i muted it. No CD either. And I don't have any

I can hear a loud 'CD spinning/fan like' sound from my MacBook Pro intermittently. Definitely not the audio as i muted it. No CD either. And the only programs running are words, safari and mail.

It sounds like the fan but this is the first time I hear it in the past 6mths using this Mac. If its the fan, shouldn't the sound be there all the time and not intermittent?

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!!

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure 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 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".
4. 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.

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.

No Sound, Safari Slow & MacBook Pro Very Slow after upgrading to Yosemite.

Hi All,
Upgrading to Yosemite has resulted in the following issues with my computer/laptop:
1. I have lost all sound and the sound options are no longer there after looking in Preferences.
2. Safari only loads parts of pages and then takes forever to load the rest.
3. Generally the computer has been slow with processes taking over the CPU and there seems to be a lot of hard memory swaps.
Attached is the EtreCheck.    Any help would be appreciated.   It appears that I also am missing some daemons that are launching.

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.

OS X Mavericks: Start up in safe mode
Starting up in “safe mode” may help you diagnose problems you’re having with your Mac.

Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart your Mac normally without holding down any keys during startup.
{The third-party utility scan you installed may be something (hard) to be rid of, too}

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!

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.
Memory in the MacBook Air is not upgradable. If that's what you have, you should restore the previous system from a backup, or replace the machine. Ask if you need guidance.
The Etrecheck report clearly shows that SylvieRose has a Macbook Pro, not a Macbook Air and that there are only 2 GB RAM installed. The Etrecheck report can be very informative if one takes the time to examine it.
Ciao.

What is the problem on MacBook Pro retina 15"?

I just bought a new MacBook Pro retina 15". After unboxing, I turned it on and there was no any problem. But the second time I turned it on and charge battery, I got 2 problems, 1. The machine made noise loudly and 2. The charging is not working. What is the problem on MacBook Pro retina 15"? However, after about 1 hour, it works normally. Should I still use it or sell it before it has more issues?

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

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.
