Audio Line Out Stuck in Optical Mode Toothpick Technique

My macbook's audio line out is stuck in optical out mode. (red light and everything) Many have had this problem and many have fixed it with a toothpick. I want to know how this is done. People just keep saying that they fixed it without explaining what exactly they do with the toothpick. (I'm looking for incredibly specific instructions) Any help would be great!

Not much to say, fixing problems while the warranty is still good seems like common sense ...

Audio line out buzz, clicks and ground hum all of the sudden?

I've developed a nasty, sharp, buzzing from my audio line-out on my iMac G5, and it's gets twice as loud and unbearable when I put the computer to sleep. When I plug in a pair of iPod headphones and play a song, NO AUDIO WHATSOEVER appears in the phones, just a steady endless series of audible clicks. All connections were tested with new cables, etc., and it didn't make a lick of difference. My guess is that this issue has something ot do with the "optical out" dual-purpose jack 3.5mm jack, like it's internal switch is stuck half-on or something-- I saw a red light when plugging in the audio cable. Has anyone experienced a problem like this on their machine?

I've read about the red light here before. The jack does indeed read the impedence and then ping software to let it know something's attached. Perhaps try several different plugs in addition to the cables you've already tried. I know some speakers and headphones here at my place have WAY different impedence values.
Some people have been able to trouble shoot by creating a dummy user account to verify it's a software problem (the problem is gone in the new account). Other people have been successful resetting the core audio by running the GarageBand program. Not sure these tricks will help you, as 60 cycle hum leads me to think there's a hardware problem.
Let us know if this is helpful (as I only need 5 more points to hit 1000!)

Connecting to audio line out freezes QuickTime!

Today for the first time I tried plugging my Apple speakers into the line out socket of my new Mac Pro instead of the headphone socket, only to discover that this prevented any QuickTime files from playing. It also caused FCPX to freeze up. Has anyone else experienced this strange phenomenon?
This was after installing the latest Yosemite update, but I cannot say whether this made any difference as I did not try this socket previously.

The Mac Pro (Late 2013) has two distinct audio ports. Audio devices you connect to the port will appear in System Preferences > Sound > Output.
Audio out: The left audio port with a speaker icon is a 1/8" stereo minijack for audio line out. It can use analog audio and digital S/PDIF fibre optic cables. Note that this port does not support headsets or microphones.
Headphone port: The right audio port with a headset icon is a 1/8" stereo minijack for headphones. When you plug in headphones to this port, sound is redirected from the internal speakers to the headphones. If the headset contains a microphone, it will appear in System Preferences > Sound > Input.
As with handling audio processing errors on a per-application basis, you can try toggling some audio format and input/output device settings in the Sound panel of System Preferences, or using the Audio MIDI Setup utility that is in your Applications > Utilities folder.
If this does not work, then you may need to reset the audio daemon, which can be done by rebooting your system; however, this may not be desired if you are in the middle of a workflow and would prefer to keep your system operating. In these cases, you can manually reset the audio daemon, by simply forcing it to quit. This can be done by opening the Terminal utility and running the following command: sudo killall coreaudiod

Faulty audio line out

The audio line out on my G5 dual-core has stopped working. There is a tiny amount of output, but not enough to drive the speakers. The headphone jack in front works. Does this mean the sound card is bad? The machine is less than one year old - should I take it somewhere to be repaired? Does the sound from the headphone jack come from the same sound card?

Yes, I am using powered speakers.

Problems with audio line out jack

When I connect the headphones in the audio line out inmediately change to "Digital out" and I don´t listen nothing, but when the headphones is unplugged I hear the music through the internal speakers normally. What can I do about? Thanks.

I need to change the logic board? or only the audio line out jack can be replace?

Premiere Pro CC & New Mac Pro - Audio Line Out Issue

I'm having a few issues with the audio line out on the new Mac Pro. For some reason, Line Out locks into Premiere Pro. When I switch programs, the audio line out device stays locked to Premiere Pro and the only way to get other programs to be able to output audio when Premiere Pro is not current application, is to go into System Preferences > Sound and click onto an alternative output and then click back onto Line Out.
Thanks,
Jon

Thanks.

Possible to use audio line out and in simultaneously ?

In the current version of MacBook Pro Retina is it possible to use the analog audio line out and line in both simultaneously ? That is playback as well as record analog audio at the same time.
Does anyone know what is the audio hardward platform (Codec, DAC, ADC, etc..) in this machine ?
Thanks!

Air has a headset jack.
You can use a splitter
Mics should be USB capable for best results, almost all headset mics are junk quality.
then monitoring or listening thru the headphones
consider using a PRO MIC , such as an Audio Technica AT2020 USB

or better still use one of these with pro XLR mics:

Audio line out

my subwoofer dell was working on my mac, but I moved it from the room to the family room and my Dell speaker and subwoofer stoped working ,,, wonder how I can test the audio line out on the mac, or if you have any ideas
thank u

Are you sure you have everything connected properly? Are you sure that your audio designation in System Preferences is set correctly?
Describe in detail how you connect your speaker system to your iMac.

Audio line out disables periodically

Running Yosemite 1010.
Late 2013 MacPro
Audio switches from external speakers to internal speakers. Restart returns connection to external speakers.
No change is made to Audio Line Out port.
Please advise.

What speakers do you have... USB or Line ?

Audio line out port (Apple iPad Dock Connector) not working Iphone 4 os 4.2

For my new iphone4, the audio line out port (Apple iPad Dock Connector)is not working. Both using a cable to mini jack (3,5 mm) or in dockingstation.
I'm using OS 4.2.
IS this a bug?
Thanks
Hans

I just came back from the Apple store. My iPhone4 DOES have a working line out when plugged into a Apple name brand dock connector. I don't know why my SendStation refuses to work only with the iPhone4 yet works with iPods, etc..
Solution? I'm buying an Apple iPod dock connector for home and will try to find something with line out for the car - Apple says they do not make one.

Audio line-out issues

Audio line out not working. Had done up till updated Snow Leopard recently. Anybody had same problem? Any fixes?!

Problem "solved". Uncertain about why though.
Disc Repair? The verify disc did show up that it needed repairing.
Resetting PRAM?
Or the speaker cables ? I put in another cable of the same type but both cables now working fine. So...?
It may be simply how the steps are sequenced.
But a nuisance when it happens.
All part of the rich fabric of Life, The Universe and Everything? Possibly.

Damaged Audio line out jack

Hope to get some advice here - after messing with my MDD to get a Time Capsule up and running (while changing the ethernet connections a couple of times), I managed to thwack the audio line out cord from the box enough to damage it - I noticed one channel of the audio was gone, then after finding the jack is loose, wiggled it just enough to make it worse or better depending where the cord sits... I am using powered speakers so the apple speaker mini-jack doesn't seem to be a good option instead of the line out...
The question is, can this be repaired without replacing the logic board?
Many thanks in advance!
David

Hi, David -
Repairing that component could be not inexpensive (if done by a tech shop) or risky (if done by someone else).
As an alternative, you could consider using the Griffin iMic Adapter.

MBP audio line out?

If I hook my MBP to my external speakers via mini cable connected to the headphone/line out port the volume control on the MBP is still enabled. Is there a way to set the output to line out only? I have a volume control on my speakers, so having two just makes it odd. I always thought line out was a fixed level signal.

The headphone/line-out port is a combination analog and digital output. If you plug in an analog connector, like your speakers, that's the same as headphones. For line-out, you need to plug in a digital audio connection (e.g. a Toslink cable) - in that case, the volume controls are deactivated (and pressing the F3-F5 keys just gives the prohibitory sign).
Note that many users have had issues with this, where the headphone port gets stuck in the digital out mode (you can see a red light when you look in there). Search the forums for "red light audio out" to see what I mean.
Hope this helps...

Toshiba Thrive Tablet Broken Headphone Jack Fix For Audio Line Out

BROKEN HEADPHONE JACK SIMPLE FIX FOR TOSHIBA THRIVE TABLET:
I love my Toshiba Thrive tablet. I take it with me everywhere I go, nearly every day. I also enjoyed connecting the headphone output jack on the side to an external set of speakers. I would enjoy stereo internet, video watching and so on. I recently broke (cracked) the headphone jack on accident. For months, I heard only through the small, factory installed speakers which, is not quite what I'd call 'ideal stereo.' Has anyone else done this? Despite trying to find repair shops locally, no one will touch a tablet it seems for repair or replacement parts. It's not your usual headphone jack. But - I can tell you how to get your sound back!
THE QUICK FIX
While browsing the internet, I found a device that by-passes the headphone jack and instead uses the internal workings of the Thrive tablet's main connection port. This port is located at the base of the unit. It will be covered by a protective, plastic tab that is removeable. Simply pry a little. This long narrow port was designed to allow you to set the entire Thrive tablet into a docking station designed for it. In this docking station are various connection pins that allow the audio to be sent out of the tablet and into the docking station. At the rear of the docking station you'll find a host of connection types: 1) audio out jack/headphone 2) USB 3) HDMI 4) 110v power supply. Simply plug your speakers or headphone cable into the new docking station and you're done! Your audio will work again. I purchased my docking station for $6.00 on Ebay. Oddly, the unit doesn't charge very well if at all while in the docking station but I've read you can simply remove the cover from your Thrive, remove the battery physically for a few minutes, return it to it's rightful place then close the cover and this fixes the problem. It's a strange little glitche. I have yet to try this yet. I did find that if I plug the cord directly into the Thrive right side as designed, it will recharge the battery as usual. I ordered a few of these docking stations which allow me to simply set the pad down depending on where I am and it will continue to charge. The docks do not come with power outlet so you'll need to consider buying additional but it works wonderfully. There are now even wireless docking stations too!
