Missing Audio Output in Macbook

i have a circa 2006/7 black macbook, running OSX 10.5.8, 2.16 GHz intel core 2 Duo, 2GB 667 MHz DDR SDRAM. we've had it for about four years now, so if this is it for this computer, i guess we'll have to deal with it. earlier this evening, i was attempting to record into garage band via the microphone input jack, and also run an output from the headphones to hear what i was recording. while inserting the cords, a horrible sound started coming out of the computer's audio. i figured i was getting some feedback or something was being plugged into the wrong port and it was creating the noise. after continuing to troubleshoot, i realized i had no more internal audio. the place at the top where the speaker's volume is empty. i have tried powering down, taking out the battery, etc. and nothing has brought it back.
what are the odds that i fried something inside? is there anything else i can do to bring back the audio?

also, to add to this, i launched garage band, and it said: Core Audio Selected Driver Not Found (-10202)

Audio output in Macbook.

on my macbook when I open "audio midi setup" under audio output it says "output is not supported". the output works fine, the speakers or headphones work, I plugin an optical cable and in DVD Player it detects the "digital output" but I can't select to change the output settings in audio midi setup. anyone know whats wrong?

Are you using a miniTOS optical cable in the headphone port?
I just got one today which I use with my amp. In audio MIDI setup, under Audio Devices, my default output and system output are both set to "Built-in Output".
Then when I select properties for "Default Output", I can configure speakers, source, format etc.
I assume this is a normal setup, because everything is workign fine, so just check that you have all the same options selected as me.
I haven'y yet tested 5.1 or encrypted audio or anything with a DVD yet though.

Optical/Digital Audio Output from MacBook

So I am interested in hooking up my MacBook to my HDTV so I can watch movies with it. I know for video I need to get a mini-DV to HDMI cable. That's easy. But what about audio? I would ideally like to have playback in surround sound. I have read that the headphone audio output also doubles as an optical output. Is this true? If so what cable can I buy and will it output surround sound from a DVD movie?

Yes, the audio port doubles as an optical in and output. You will need a optical cable from your macbook to your sound system to have surround sound/dolby digital, and when you play the dvd it should automatically convert the output to a digital signal. I have this setup on my iMac and Macbook. I have the logitech Z680 (now Z-5500), and when I play a DVD, the screen on the controller says 'digital'.
The cable you'll need is a optical audio cable 3.5mm (for the macbook) to a toslink (square shaped with two corners tapered). You can buy cables which are toslink to toslink that come with adaptors for 3.5mm jacks.

4 channel audio output? (MacBook)

I am looking to get 4 channels (2 sets of R and L) of audio output from my MacBook - I'm trying to work with DJ software to enable monitoring (listening to a track on a separate channel thru headphones w/o playing it through the main speakers). If I would hook up a USB audio interface, would this interface, along with the 1/8" headphone output, give me a total of four channels?

It depends on the software you are using and the hardware you want to buy.
You would need to set up an Aggregate device in Audio/MIDI manager (in the Utilities folder). Once the Aggregate is created you would then be able to select it in any software that fully supports Core Audio for I/O. The Aggregate device allows for all the inputs and outputs from different interfaces to appear as one single interface to the software.
Some hardware comes with Core Audio drivers that won't allow Aggregate devices. Digidesign is the only one I have ran across yet, but I can't guarantee there aren't others.
Also when you create an Aggregate device the different I/O could have different latencies, which could cause issues for you. If you don't know latency is the delay between when the audio is input or played back, and when it is actually heard coming out of the outputs. Firewire interfaces tend to have lower latency, and your software should have settings to adjust the latency as well.
But yes, it is possible, although it takes a little bit of work.

Macbook pro to hdmi video/audio output TV

I Bought a mini display port to hdmi cable, to play dispaly my desktop on my LCD TV. the display works just fine, but there's no sound. I try to follow the steps in youtube, but the problem is, there's no sound output detected. Any ideas on how to solve this? Because, what i know is that hdmi can both deliver hdmi video and audio.

Using Macbook Pro's Audio Output

Hello
I'm considering a purchase of an Apple TV so I can stream films up to my projector which is on the far side of my room. However my Macbook and speakers are on the other. Is it possible to stream content to the Apple TV but use the Macbook's audio output (either via the Macbook's headphone socket though preferably via a sound card) and send that into the speakers?
Thanks in advance.
Dom

Poop. OK thanks for the clarification.

Xbox digital audio input and then output through MacBook digital audio port

Hi,
Sorry if this has been asked before but I'm trying to output a Dolby Digital (I think AC3) signal from my Xbox 360 into the MacBook's digital audio input and then output it through the digital audio output. I can output 5.1 sound from the MacBook itself but I can't get the Xbox audio to pass through. I don't know if the audio is at a sample rate not supported or needs decoding or what!
Any help would be appreciated!

If that doesn't work, I'm not quite sure.
A combination of the Audio MIDI Utility (in Applications/Utilities), SoundSource, LineIn, and Soundflower (http://cycling74.com/products/soundflower/) might work, otherwise I'm stumped. Your best bet is probably a dedicated external USB or FireWire audio interface.

Audio Input Output on MacBook Pro 13 inch

I want to buy a MacBook Pro 13 inch but the problem is the audio input output port.
I usually need to use both jacks because in one I record my guitar and in the other I use my headphones.
Is it possible to get a splitter and to make from one jack, two, input and output or do I need to buy USB headphones?
A splitter would be the best solution

From the manual:
+"*Audio out port.* Connect external speakers, headphones (including iPhone), or digital audio equipment. You can specify audio analog line in functionality, to support line-level microphones and audio equipment, by selecting Audio In in the Sound pane of System Preferences."+
+"Choose Apple () > System Preferences, and open Sound preferences. Specify whether you want the port to be used for audio input or audio output."+
This means you must choose whether you want the single audio port on the 13" MBP to be input or output. It mentions iPhone headphones, but those will work only as headphones, not as a combined mic/headset when connected to the MBP.
(As in, "Oh, now I get it!")
Thinking on your comment, I see what you mean by 'an extra port' - the iMic has both in and out, meaning you'd actually have three counting the internal port on the MBP.
Looking back at your first post, you mention USB headphones. That would be fine as well - set the MBP's audio port to be used for input, and connect the USB headphones and use those for output. No 'extra' port that way, and USB headphones are cheaper than an iMic.
EDIT: The caveat there is that the audio in on the MBP (true for all MBPs, not just the 13") is a line-level input, not a microphone input. So, the MBP is expecting a line-level signal, meaning preamplified audio. If your guitar puts out a line-level signal or you're using a powered mic, fine. Else, you may need the iMic, which can take either line-level or microphone (non-preamplified) input.

Audio Output Device Missing

MacBook Audio Output Not Working, Except for Garageband?

Good day everyone,
I have a 13-inch MacBook '08, current version 10.6.8 (can't upgrade to OS X Mavericks – hardware is too old), and I've had a serious problem, and I feel that I've tried EVERYTHING to fix it.
My Macbook audio output does not work AT ALL while trying to stream video (i.e. YouTube, Vimeo, etc.) or listen to music. When I play with the audio adjustment buttons, it doesn't even make the "popping" sound. It DOES however have audio output when I open Garageband and play the instruemnts i.e. Grand Piano. It also plays the "start up" sound when I boot my MacBook up. Otherwise, the audio seems to not work at all.
I've played with the "Sound" settings on "System Preferences." I've played with the audio jack (note: there's not red light, so that's not the problem), I've blown into the hole, stuck paper clips in there and fiddled around... nothing. Please help, I'll take any advice!
Thanks in advance.

Well, even though the input jack had no red light, I performed the actions demonstrated on YouTube in the video "How to fix macbook red light head phone jack" and the problem is fixed.

MacBook's Audio outputs for deejaying problem.

OK. Here's the scenario.
As you all know, the MacBook has one audio output that also serves as a digital output, so it's one or the other. I have that output connected to an amplifier via the digital option. Since I'm going to use the laptop for deejaying, I also bought USB headphones to use as the cue for the DJ software (Torq). The problem I'm having is I can't put two different sources for the Master and the Cue. I can, however, choose one source and specify the channels. For example, I can use channel 1 for Master and channel 2 for Cue and have two mono channels. This doesn't help either because I'm using the digital option for the output to my amplifier. I've also tried SoundFlower to no avail because in the DJ program, there are 2 sources for SoundFlower, one with (2ch) and the other with (16ch).
Any suggestions or anything that will help me solve this problem will be appreciated.
If there are external sound cards or anything of the sort please tell me.

Hi,
I just saw this.
Yes... there are many, many audio devices available that will give you the options you need.
There are both Firewire and USB options.
However, you may be able to get this going with what you have.
In AudioMIDI setup, (in Utilities folder) create a new Aggregate device.
I'm hoping the USB headphones show up there as an audio device.
Basically, you create a new aggregate device, use built-in audio for the Input Device, make it clock master, include all of your output devices then name the Aggregate device.
It should show up in your audio programs and allow you to select what outputs you need.
Don't know if it will work but worth a try.

IPhone Audio Output vs. MacBook Pro

I've been the owner of the Apple In-Ear Headphones for a while now, and have experienced an improvement in the sound quality between the in-ear and standard iPhone headphones.
However, I've recently been using the same in-ear headphones with my MacBook Pro, and noticed a significant difference in the quality, depth, and volume of the sound. When playing the same songs on my MBP, the headphones are capable of much louder volumes, much clearer audio, and are much bassier than when using my iPhone 3G S, yet the audio tracks are identical.
Is there any specific reason why my iPhone isn't capable of matching up to the quality of my MBP?
Many thanks

I wanted to chime in after my latest show-down between my iPhone 5 vs. iPad 3 vs. MacBook Pro 2010. My medium of choice is vinyl for hi-fi listening, but otherwise I prefer Spotify @ 320kbits.
I plugged them into my hi-fi system: rega brio-r amp, wharfedale diamond 10.1 speakers, standard [decent quality] 3.5mm to RCA cord to plug in each device. No DAC in my setup. No cable splitting-- all directly plugged in.
I used the latest Arcade Fire album, Reflektor, 320kbits from Spotify. I think the album has enough dynamic range to make it a good test subject. I started the test on track 2, that song in particular having a lot of dynamism.
The breakdown:
Iphone5 and iPad3 both sounded identical. Everything sounded good on first pass until I plugged in the MacBook Pro. The MacBook revealed an enormous difference in better audio quality! The MacBook output crystal clear highs and the lows also had a "thump" that the iPhone/ipad did not have. That difference right there showed that the MacBook is simply capable of handling a higher spectrum of sound. With a higher spectrum, and the ability to differentiate the highs, mids, and lows helped give the sound much more dimension.
Bottom line:
I wish I could turn back the clock on all those hours I spent listening to my iPhone. Without a doubt, the MacBook Pro has a much higher quality audio output. I think this is attributed to the fact that the MacBook actually has a SOUNDCARD while the iPhone/ipad both have like integrated circuit boards. It's the dedicated soundcard on the MacBook that gives it its advantage.
To break it down to hi-fi thinking, when a stereo has separate modular components that are dedicated to doing 1 thing well, there is a better opportunity for higher quality sound. That would be in comparison to an "all-in-one" unit that crams a lot of electronics into a single "stereo" system. Generally, the overall quality of the "all-in-one" will be hampered by what are basically the limitations of engineering and production; each new component/feature they cram on the same circuit board compromises the overall integrity of the whole. What I'm trying to say is that the MacBook is more like a modular setup with dedicated components, and the iPhone/ipad are the "all-in-one".

HT202730 Macbook Pro Optical Audio Output Toggles On/Off

My Macbook Pro optical audio output seems to switch off with a loud click when sound is not playing for a few seconds.
Then, when sound resumes, there's a delay as it switches back on.
Is there a way to stop this toggling?
And please don't tell me to check the connections.
I've already tried different sample sizes and bit rates to no avail. It seems as if the system is switching something when there is no audio being played, then switching it on again. Even if the playback is only on pause.

Audio output switches randomly (MacBook Pro 13" 2010)

Hi,
I have recently bought my MacBook Pro. It works really good but unfortunately, there is a problem. When I'm listening to my music with my headphones (Koss Porta Pro), after about 20 minutes of listening, the sound keeps turning off and on. I found out that when this happens, the audio output randomly changes from Headphones to Digital output. When it switches, the sound is muted for a while. Really don't know how come is that. Could you please help me?
Thanks for Your answers.

.....and then I blew into the headphone socket. Instant success with sound restored. I can only assume that some dust particle was in some way mechanically interfering with a switch?
Moral.. check the obvious, easiest and cheapest possibilities.

Apple TV2 missing analog audio output for multi-zone system

Found out the hard way that most receivers can't support digital audio in multiple zones (i.e., Zone 2). Since Apple TV2 (ATV2) dispensed with any analog output, if you have a whole-house system that depends on mult-zone to distribute audio to various speakers, you won't be able to use ATV2 to stream music to anything other than Zone 1. The only outputs are HDMI and optical (both digital audio). I think I found a work around (which, of course costs more money) which is a "de-embedding" device from Atlona that takes HDMI in and splits out the audio to analog and passes the HDMI through to the receiver. The analog audio output then lets me connect to the analog in on the receiver so it can stream to all zones. I figure Apple just didn't have enough real estate on the new product to make room for analog, but it's a pain. Hope this helps someone. If anyone knows a better work-around, I'd love to hear it.

I have the same issue with a MacMini I use for music. My solution was to use an inexpensive optical splitter - one feed to the optical input of my receiver and the second to a DAC. Then run standard RCA audio cables from the DAC to the analog Zone 2 inputs.
Here is a link for a DAC
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10423&cs_id=1042302&pid=6884&seq=1&format=2
They should have the splitter as well.
