SOUND PROBLEM ON MACBOOK

. No sound working. Sound icon is grey and the only option available in the sound panel is numeric output. I've re-install the OS and nothing seem to work.

It sounds like your sound output is broken.
Contact Apple using www.apple.com/support/contact if you are in a country that supports it or call the appropriate phone number on this page. Alternatively carry the MacBook in to an Apple retail store or service provider to ask for an estimate.
Best of luck.

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.

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

MacBook Pro with Beats By Dre Headphones sound problems

I was just curious if a short in the Beats by Dre cord will cause a problem with the overall sound of a macbook pro? I ask because during FaceTime calls when I disconnect the cord my macbook makes loud scratching noise until I adjust the volume with the volume buttons? Anyone know what this may be?

TS3276 I have no sound on my MacBook Air for sending and receiving messages. All sound settings have been checked and are OK. This problem has arisen many times and is intermittent in the sense that the sound returns and disappears for no apparent reason.

Sound problem macbook pro

The sound from my macbook pro speakers has suddenly become muted/very faint. I have checked sound settings in system preferences and all on loudest settings. Any suggestions?

Speaker Volume.
A small amount of your computer’s memory, called “parameter random-access memory” or PRAM, stores certain settings in a location that Mac OS X can access quickly. The particular settings that are stored depend on your type of Mac and the types of devices connected to it. The settings include your designated startup disk, display resolution, speaker volume, and other information.
Time settings may change.
Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
Other than the time setting, resetting PRAM or SMC will not have any adverse effect.
If you see red light in the headphone port, plug the headphone into and out of the port to flip the microswitch
inside the port. Sound may be stuck in the digital mode.
Best.

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

    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 ?

Mac os 10.8.5 sound problems

After update I have problems with sound trough HDMI? Any solutions
/M

Same problem here, Macbook Air and HDMI external monitor.Tried Repairing Permissions as suggested on another thread but that didn't help.
Really makes me wonder how Apple didn't see this one coming and fix it before rolling out 10.8.5. I'd imagine an external monitor via HDMI is one of the more common setups people have these days. Losing sound after sleep is a major system failure. I have still found no other solution than rebooting the laptop and disabling sleep mode completely. Now my macbook has severe insomnia.

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.
