No sound from Macbook Pro after restart or sleep

I know there are a lot of threads on this type of issue, but I haven't found a way to solve my problem.
My computer:
Late 2008 MBP 15" OSX 10.9.5
Whenever I shutdown or sleep the computer, the sound does not work when I start it up or wake it up. The startup sound does not play, and the audio controls are not greyed out. Audio does not work through headphones either. Plugging in and unplugging headphones does not solve the problem.
Sometimes a PRAM reset will solve the problem, and an SMC reset always brings the audio back, but only until I shut it down or put it to sleep again.
Any help in finding a permanent solution to this problem would be greatly appreciated.
Thank you!

Hello CoDean,
Continue your troubleshooting with the article below to assist with the issue of not sound on your MacBook Pro. Look at the headphone jack to see if there is a red light coming from there as well as looking in System Preferences > Sound to see if the output is stuck on digital out.

No sound from MacBook Pro under Lion OS X after the automatic logout.

When I go idle, my MacBook Pro does the typical log out....& prompts me for my password to get back in. I have sound previous to this, but, when I log back in, all the sound is gone. This frequently started happening with Internet videos (youtube) / flash getting no sound, but now it's the entire system. In order to get sound, I have to shut down my entire notebook and start back up.
When I click the sound effects in the System Preferences > Sound .... They do work.
Any solution to this sound issue?
If you need more information please ask.

Hi. Same here. I haven't try the PRAM reset, but rebooting the system works, with the obvius corresponding time consumption .
The system has two user accounts that are running simultaneously, my wife’s with Chrome, VLC, and other image and video tools (no professional ones). On my profile I have chrome, vlc, jdownloader, mail, mkvtools and stuff like that.
I first thought that one app was blocking the access to the sound card to the other apps, but if I turn off all of them and log out one user, the problem persists. So I end up rebooting the system…
Any help will be appreciated

Weird sound from MacBook Pro 2011

I have a weird sound that occasionally occurs from my Late 2011 13" MacBook Pro. The sound comes from the left side of the base, towards the hinge. The timing is random, usually when sitting by itself idle with the lid open. It has occured when the charging cable is both connected and disconnected. Performing a restart does not cause it to stop, it will continue thru the restart. Shutting down completely does shut it up, but it'll likely appear shortly after booting up. Closing the lid of the MBP will shut up the sound, and if left closed for a couple hours, the sound doesn't appear for awhile.
The sound itself is pretty loud, and can easily drown out my TV when it kicks in. I don't think it's the fan, as I've heard the fan on full tilt and it's still quiet, unlike this noise I am referring to. Plus, the fan is located in the center against the hinge, not on the left where the noise is coming from. I tried resetting the SMC and NVRAM, no luck. I did record the sound with my cell phone, here is a video of it:
http://www.youtube.com/watch?v=OgutF9bZilI
If anyone has an idea of what is causing this sound, please help. Thank you.

Does the sound, or it's basis, interfere with operation of the MBP in any way? When the lid is closed it is in sleep mode so one would expect the sound to stop then.
Best thing might be a visit to the Apple store genius bar to have the techs test it.

No sound on MacBook Pro after 10.6.8 upgrade

Good morning.
I've got an 5,1 model MacBook Pro (aluminium unibody) 4gb RAM, 2.4GHz Core2Duo and it's been working fine up until yesterday when I installed the 10.6.8 Snow Leopard update.
Since then I get no sound through earphones or through the internal speakers.
If I ALT+Click the speaker icon I get two outputs:
Soundflower (2ch)
Soundflower (16ch)
I've no idea what Soundflower is, and a spotlight search just shows up sound.log which refers to
6/23 18:54:29.163 => WoW Version 4.1.0 (14007) Apr 29 2011
So that looks like World of Warcraft (just started WoW and logged in, turned sound off, turned sound on and no sound from WoW either)
Looking at the log in the console and narrowing it down to Soundflower I see:
6/25 10:50:02.974   --- [1] Soundflower (2ch)
6/25 10:50:02.976   --- [2] Soundflower (16ch)
6/25 10:50:02.980 ** Using Driver [0] System Default (Soundflower (2ch))
Anyway, I can get no sound in anything since 10.6.8!
Any ideas?

Okay, I tried EVERYTHING.
Trust Me.
I even did the downgrading to the 10.6.7 HDA.
HERE IS THE SOLUTION:
YOU WILL NOT NEED TO LOOK ANYWHERE ELSE, IF YOU FOLLOW THESE STEPS:
1. Download and install the 10.6.8 Supplemental Update from Apple (link below).
                            http://support.apple.com/kb/DL1429
2. Once the update is installed, and the system has restarted, type "Disk Utility" into Spotlight, press enter to launch it, and select your hard drive on the left. Then click "Repair Disk Permissions." (This step may or may not be necessary, but is a good idea in case there are discrepancies from the update).
3. Once the utility is finished, plug in some headphones. Then, press the Option key and click on the speaker icon in the menu bar.
4. Click the Headphones option under the "Output Device" section. You should get sound.
Unplug the headphones and ensure that the audio is not muted. You should now also get sound through your speakers.
THIS WILL WORK. DO NOT MESS WITH VOODOO, etc. I hear that will just cause kernel panics.
If you still have problems, try resetting the PRAM by simply shutting down the computer. Hold Command+Option+P+R before the gray screen appears. Hold it until you hear the tone a second time, then release.

Random tick sound from MacBook Pro (noticed it since updating to 10.6)

Hi,
I have the 2.4Ghz Unibody MacBook Pro 15" (Early 2009) with the removable battery.
I went through a clean install of Snow Leopard, up to date with all the updates (10.6.1). Ever since I have been hearing random ticks. At first I thought it was the hard drive. But it's too loud for the hard drive, and it sounds like its coming from the right speaker.
A break down of the possibilities:
- Hard Drive
- Left Speaker
- Bug in Snow Leopard
- Fan
What do you guys think? Anyone else experiencing this?

If you had a cloned copy of your Leopard (not Snow Leopard) disk (everyone should have a backup of their disk on an external drive) you could boot from it. This would rule in or out the OS as the culprit.
If you do ot have said copy (for shame, for shame) maybe you can boot with the install DVD and determine the same thing.
I have the mid '09 15". I can remove the belly pan and see the entire fan. Can you do this with your model to determine if the fan is making the noise? Can you install some fan control software that will allow you to speed the fan up and thus determine if the fan is the noisemaker?
Will turning the speaker audio OFF have any affect on the noise? Will putting a piece of cardboard over the speaker grill affect the noise?

Stream sound from Macbook Pro to another device?

So my headphone jack just half-died on me. I get full sound from the right ear, but the left one has little to no sound coming through. I've had headphone jack issues in the past with my macbook pro and they said I needed to replace the entire motherboard last time which was extremely expensive. My warranty has run out so doing that again would not be feasible, yet I really need the headphone jack to be working since much of my work is video/audio intensive. Is there any way I could stream audio to another device like my phone or something via bluetooth and plug headphones into that to get full sound in both ears? Or is there a fix to this issue that I don't know about? Any tips or advice would be greatly appreciated!
Macbook Pro 13-inch (early 2010)
2.4 GHz Intel Core 2 Duo
10 GB 1067 MHz DDR3
OS X Mountain Lion (10.8.5)

You can stream audio via airtunes to an Airport express which has an analogue ouput jack, but it's line level and doesn't have a volume control, but you can use it as the source for a hifi. You can get third party powered speakers which receive airtunes. You can stream audio and video to an Apple TV but it only has an optical Tosslink audio out and audio and video out via hdmi.
You can also get sound out via USB to a an offboard D/A converter which in most cases would be line-level, though you could likely find asomething with a headphone output with a volume control.
If you look up the specs on your machine you might also find you have digital audio out via tosslink and the headphone jack which is misbehaving as the ports are combined on some models. Then there is the mini display port which can in some cases output both sound and audio and you can get a long display port to hdmi cable a lot cheaper than an ATV.
But, while the headphone jack replacement involves a motherboard swap, in reality, what might have happened is that a solder joint for the socket on the motherbord has failed and simply resoldering the joint would fix the issue. If the internals of the socket like a contact breaking or being damaged is the problem then the MB would likely need replacing given the cost of labour for a tech to source and replace the whole socket.

No sound from MacBook Pro

Last week, I tried to play music through my MacBook Pro. No sound is coming from either my internal speakers OR my headphone jack. I feel like I read a million threads but none of them seem to apply to my issue. In my Settings>Sound it still displays my "Internal Speakers - Built-in" as the sound output. When I try to adjust the volume, the icon appears normally on the screen. There is no line through it, or simply doesnt work, as other users have posted. I have no red light shining from my headphone jack. Headphones also do not work. Everything (software Wise) seems to be set up exactly as it should be, but still no sound! Could this be a hardware issue? From the time my sound worked to when it stopped working my MBP was just sitting on my desk! Not sure what else to try. Any help would be greatly appreciated.

Asher,
Sorry for the delay in response. Thankfully, a tech person with whom I work discovered the update, so I am not totally sure. I think that she simply switched my software update schedule to every day (instead of weekly), and the firmware was simply part of an update package that was waiting for me. Sorry that this isn't too helpful. I'll try harder to remember to ask her how exactly she accessed the update.
Kindly,

How to output sound from MacBook Pro to stereo receiver/amplifier?

Does anyone here know what I would need to buy to send audio from my MacBook Pro to an external integrated stereo amplifier? I'm sure there's something. I'd like best quality so if you know of a USB solution please let me know.

Typo above, 'headphone port' not 'headphone post.'
Glad to help, and thanks for the !
FYI, the mic port is the same, so if you have a need to get digital audio into your MBP, the mic port will do that as well as analog.
The headphone port actually does triple-duty, in that it's both analog and digital out, and with the longer plug found on the iPhone headset, the headphone port can also function as an analog input.

Odd alert sound from Macbook Pro Retina

Hi, my 13-in MacBook Pro Retina is late 2013 version installed with OS X Mavericks 10.9.4.
Recently, every now and then there will be a "ding" tone that sounds.
I have checked. I do not have any alerts on nor is it the incoming email alert.
I also could not find this sound under the sound alerts menu.
Anyone can be of help?

sorry to hear about your problems. Try running Audio MIDI, see what's it's set it for both the line out/digital out. Holding down the Alt Key (next to the space bar) gets you a list of all the input and output devices on your macbook pro. Also, see if accessibility is turned on under system preferences. Other than that, I can't say. if you have wifi problems, see if there's an update for it (airport?) or see if you can change Wi-ifi channels on your printer
well, I tried anyways

Can I direct all sound from MacBook Pro to Airport, not just iTunes

Hi, want to be able to choose AirPort for all audio out from my MacBook Pro, not just iTunes. Is that possible? For example I would like to stream YouTube music via AirPort...
Any help is most appreciated.
/R

Hi!
Thx for answer. However, I can not choose AirPort the way you described, only "internal speakers or Thunderbolt/external monitor speakers". Seems like it's only in iTunes one can choose AirPort output. I would like to play all aduio out via AirPort.

Tinnitus similar sound from MacBook Pro

Since yesterday my dear MacBook Pro had such an annoying tinnitus similar whistling. Anybody who know why it does it, and how to fix it?

There are really only two possibilities - your hard drive is failing or your fans are causing the constant noise.
If I were you, I would take the machine to your local Apple Store or an AASP and see if they can find the root of the problem.
Good luck,
Clinton

Random trumpet fanfare sound from Macbook pro "15" retina

I have this problem that really annoys me sometimes it's just that my macbook is making a sound like a trumpet fanfare, and it just happens randomly, not at any specific moments and i have no clue what that could make that sound, i usually only have safari, mail, skype, spotify and league of legends open, and i can't see what could cause the sound, cause there isn't any commercials when the sound comes, and i don't know what to do

Do you have Growl by any chance?
Temporarily disable the notifications by clicking the icon in the upper right hand corner of your menu bar. See if the problem persists.

5.1 surround sound from macbook pro, external soundcard (USB)

When I started up my macbook Pro after a boat trip (just lying in my bag the whole time) it started making weird sounds. Why does it do that and how do I stop it?

When I started up my macbook Pro after a boat trip (just lying in my bag the whole time) it started making weird sounds. Why does it do that and how do I stop it?

The 13" retina MBP has two fans, left and right near the hinge and about 2.5" each from the edges of the case.
My conjecture is that one of the fans may be failing. An appointment at an Apple store genius bar is the best option. The evaluation will be FREE and a fan replacement (if that is the problem) should not break the bank account.
You might run an Apple Hardware Test:

This may confirm my suspicion or perhaps find a different problem. Note that an error free result should not be viewed as being definitive.
Ciao.
