Sound Output on MacBook - Not loud enugh

I've been using a MacBook for quite a while now and I've noticed that the sound output for programs such as Front Row is not loud enough to be able to use it from 10 feet away which is what the interface is about.
iTunes volume levels are higher but not that high, all levels in System Preferences are set to maximum.
Any suggestions or software to fix this issue???

Hello,
Most notebook sound devices usually produce hallow sounds and are normally harder to hear at higher distances. Your best bet, rather than to push the limits of the speakers, ( they aren't great ) is to hook your laptop into some external speakers made for this type of operation. I usually hook my Macbook up to the TV along with my home theater system when I am using Front Row. I highly suggest you do the same.

External sound output on Macbook Air stopped working

Two months ago, my Macbook Air went silent.
I tried every trick I was suggested, including upgrading to Mountain Lion OSx , after which sound came back for a few day then disappeared again.
Their is no external speakers listed under <system preferences / sound / output>
Internet is full of this complains, I mean it is not regional and limited to a particular version of hardware/software... complains are coming from everywhere across the world since 2008.
Unfortunately tech support at Apple appears to have no clue as neither hardware change nor software update / upgrade doesn't seem to solve the issue permanently. But they still replace parts and software for some reason, just to drive people crazy later.
I am confident that this issue has already been told to design team , the problem was known for years after all.
What is this? Does Apple expects people to trash their computers when this happens? and get a new one? Is this because Apple asks new customers if they want to recycle their old computers with them?
You probably think I am an Apple hater , I am not. I like their products but I hate their tech support, I am sick and tired of listening to so-called geniuses , bunch of untrained high school kids with a lot of BS.
Only hope I have left is, somehow, there maybe someone out there who already solved this problem... Are you there?
MacBook Air specs :
Processor 2.13 GHz Intel Core 2 Duo
Memory 2 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 9400M 256 MB
Software OS X 10.8
Other Apple products I use together with this Mac :
Magic mouse
Apple TV latest
iPad latest
iPod touch 4th gen.

I finally found the solution,
the solution itself actually explains why Apple was so silent about this issue
because every macbook that was sold over the last 5 years was defective ,
it will probably cost Apple $100s of millions to recall them
It is the Audio Board Flex Cable, Part #: 922-8380
this cable goes bad quickly,
it is defective because this is strickly a design issue
I opened the macbook and replaced it myself,
all looks fine now

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 -

Can't switch sound output device macbook air/mountain lion

When I choose my Airport Express for music coming from iTunes, the audio does switch to the APE, but even the lowest volume setting is fairly loud. The F11 and F12 volume keys bring up the indicator bars, but there is no change in the level coming from the APE. Additionally, the Sound Preference still says Internal Speakers. If I try to change ouput device to the APE (AirPlay) it won't let me. Any ideas?

i got same problem too but it's 2011 macbook pro 10.6.8 also SD card out of order as well and it's horrible computer I ever have. no more mac

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

Sound output stuck on Airplay on OLD Macbook Pro

This should not even be possible, since AirPlay is not even available on my late-2008 Macbook Pro...but my system preferences show that sound is being routed to my AppleTV via AirPlay!!
I have zero sound coming from my Macbook. None with speakers attached, and none with nothing attached at all. I go into System Preferences>Sound>Output, and AppleTV is somehow, impossibly, selected. I can not unselect it.
I have rebooted my laptop, and rebooted AppleTV, and nothing works.
Help!

Have you tried SMC or PRAM reset?
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Plantronics Voyager Pro vs. Macbook Pro sound output

I just bought the Plantronics Voyager Pro bluetooth headset to use with my iPhone in the car. It works great. As an experiment, I tried pairing it additionally with my 2007 Macbook Pro. I can hear sound output from some apps but not others, for example, I can hear music in iTunes, but not YouTube videos in Safari. It seems like I should be able to hear all sound output, not just some. Any suggestions appreciated.

The "bug" is specific to sites that stream such as youtube. The sound on my jawbone works with every application including safari but not when I navigate to a website that streams.

Connect Macbook (1st Gen) sound output to Plasma TV

Hello,
i have the appropriate connections to hook up my video output on my macbook onto my plasma. but now im trying to figure out how to connect the sound from my macbook to the tv. i have a plasma tv and has an optical input or whatever. does anyone know how to appropriately hook up the sound. could someone provide pictures of the certain wire i would need to do this? thanks.
i have the first generation macbook with the 3.5 headphones input and the other optical input im not sure what its used for.

hey, sorry i havent been on here for awhile. nah i havent gotten an answer yet. i bought different cords such as toslink to mini and a rca to 3.5 headphone jack and neither of them worked. the only time it actually worked is using a separate sound system, but i want the sound to come out of the tv speakers. if you find anything let me know please. thanks.

No sound from my Macbook Air. When I go to system preferences and click on Sound Output there are no devices to select from and the Mute box is checked.

There is no sound from my Macbook Air even when I turn it on. When I go to System Preferences and click on Output there are no options. The Mute box is also checked, but I cannot uncheck it. Also when I try to play any video from the web, it stops playing after a second or so. I have turned off my computer and turned it on again which did not help.

Try these
PRAM Reset: http://docs.info.apple.com/article.html?artnum=2238

Does anyone know why my macbook pro doesn't use sound output anymore?

Hi, I have a Macbook Pro w/ Mountain Lion (10.8.2) and I don't know why or how, but the sound just stopped working. I can use headphones or my bluetooth speaker, but the speaker coming out of the keyboard doesn't sound anymore. Anyone else have the same problem or know the solution? Any advice is good. Thank you.

Hopefully one of these steps should solve the problem.
System Preference > Sound > Output > Internal Speakers
Make sure Mute is not enabled.
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 output (except for start-up chime) on MacBook Pro

I've been looking all over the discussion boards but haven't been able to figure this one out.
Suddenly for no apparent reason I have no sound output. I've checked all the settings, repaired disk permissions, restarted, etc. with no effect. I DO get the start-up chime but then nothing. Also, I do NOT have a red light emitting from my adio out jack. F3, F4 and F5 show the volume icon changing on-screen but with no actual sound output. Switching to a speakers or earphones doesn't change it either.
The only thing I can think of is that my battery has been slowly dying and has just recently started to crap out when the battery life indicator shows more than 50% charge. For this reason the computer has lost power and suddenly shut down once or twice without having been properly shut down. But the loss of sound input did NOT happen directly after this.
Any suggestions?

I Finally figured it out...
For some reason, my audio setting got changed in my audio prefs:
System settings --> Audio
On the "Sound Effects" tab, it was set to "Internal Speakers", which explains why I was getting the startup chime, and alert sounds just fine.
However on the "Output" tab, it somehow got changed to "Sunflower" which causes the sound not to work. As soon as I changed it to "Internal Speakers" everything went back to normal.
Hope that helps!

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.

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!

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
