My audio out automaticly switches to digital out

When I start my computer my headphones audioout works fine for about 5-10min. then it automatic changes to S/P-DIF and I don't now why. The choice "headphones" in systempref. sound menu dissapears and replaces itself with Digital out.
Can you please help me.

Make sure the earphone jack is pushed all the way in. On iDevices it takes more force than typically.
To rule out hardware issues, check your headphones with another audio source. Check your iPad with a different set of headphones.

Audio port automatically changes to digital out

Hi,
I want to record audio from my MiniDisc unit to a 13" MacBook (Mac OS X 10.6.8) using GarageBand, Audacity or similar.
The MD unit is a Sony RH1, which has a Line out port. I connected this via a 3,5mm TRS connector to the combined Audio port of my MacBook.
The problem is that as soon as I plug in the other end of the 3,5mm cable into the Mac's Audio port, the computer's settings switch automatically to "Use audio port for digital out". I cannot choose to use it for input anymore. Using a Mini-TOSLINK cable instead didn't solve the problem.
How can I use the Line-in option of the MacBook to record audio in real-time?
Thanks in advance!

Talked to Tech Support about this when my machine locked up in this same fashion. There's a little "door" inside the headphone jack that can get stuck in the open position and keep the audio from switching back to the internal speakers / stuck in the digital (optical) output position...
The solution: the iPick... It's a toothpick, but if you use it to poke around inside the headphone jack until the little door gets unstuck, it becomes an iPick, and a box of them are very expensive, but they come in lovely colors and are very intuitive to use...
I'm not kidding... Stick a toothpick (or other non-conductive small stick) in the headphone jack and joog it around until it releases the little door...

Audio doesn't switch to headphones when one is inserted (Chromebook 2)

How do I switch the audio to be output to headphones instead of the speakers? In all my previous laptops I just had to insert the headphones into the jack, and the audio would automatically switch. Not the case with the new CB3-B3340 chromebook 2.
Am I missing something?
Thank you.

MBP- Digital Audio Out is always on

For some reason after (I believe) I updated to 10.4.9 the Digital Audio Out on my MBP is always on, thus making the internal speakers unusable. If I plug in headphones they work fine but after I unplug them it switches back to digital audio.
How do I fix this?
15" MBP 1.83ghz. Mac OS X (10.4.6) 1.5gb of Ram,

ok, since this prob comes up every week and often more than once a week, I wrote a detailed explanation and saved it so I could repost it next time it happened to someone. here it is:
the audio input/output connector on all mac notebooks is a dual function connection. it can switch between analog and digital optical. the way it does this is by an automatic sensor that detects what is plugged in. if it detects that an optical digital cable is connected, then it will switch to digital output and/or input mode as the case may be. this is why you see a red light - it's the optical digital audio stream. it seems that in many cases, people's connectors are becoming stuck, and the machine thinks there is a digital optical cable plugged in. it can happen if you've connected or disconnected headphones, or speakers, or possibly even if something is loose in that port and it just gets jammed with the sensor being tripped. people have suggested trying to gentle poke inside the port with a paperclip, to try and reset the sensor back to the setting that nothing is plugged in. for some people it has worked, for others, not. you can also try plugging in headphones and unplugging them a few times to see if it does the trick. if none of this works, then unfortunately the best bet is going to be taking the machine in for a service.

Digital audio out port

I am having a problem, quite opposite to what most of what I've read about Mac audio port issues online, concerning my audio-out port. I'm running an Intel Imac, 7,1, running OS 10.5.8. The specs do specify the audio port on this mac is dual; analog and digital output. Everything I've read to date relates to the red optical light being stuck on coming out of the audio port. My issue is that I CANNOT, and I emphasize that, get the red light to come on and thus use my optical cable (it's working on other equipment) and connect it to my AV receiver. I have never in the past even thought about using an optical cable so it never was an issue. In fact I never knew the port was dual. The external speaker and headphones work fine and the audio panel in the preference pane reflects that; either says 'internal speakers' or 'headphones' automatically when engaging/disengaging audio phone jack. When I put in my toslink (optical) cable, the panel goes to 'headphones' instead of 'optical out' or 'digital out'. There is never a provision to click on digital out on either the sound panel or the midi setup panel. I've tried everything I can click on at both panels. Audio Output in midi setup says 'master stream' (always greyed out) and Source- either 'headphones' or 'internal speakers'. The default and system output drop downs never give me a 'digital' or 'optical' option. Everything works fine except that I cannot get the red light to shine and cannot get digital out at all. Any ideas? Maybe something in terminal or in openfirmware screen? Thanks.

have you tried other speakers or headphones and what version bootcamp drivers are you using?

Does this port connect directly to appropriate digital speakers?
If so can someone recommend a decent set of digital speakers that will connect directly.
Or does the optical digital audio port connect to an amplifier or receiver and them to speakers?
With the suggestions i have below the set-up is like this:
Subwoofer - Connects to 2 (Stereo or technically 2.1) or 5 (5.1) speakers
The subwoofer connects to a control pod (which has the optical inputs, coax inputs, and analog inputs - atleast all 3 are on the z5500)
Digital/Optical Audio:

Suggested Speakers; I Personally have 2 pairs of the Z-5500 set, true high quality audio and variety of settings for whatever you use them for, i have been so pleased by them and their warranty service is by far the best ever, anything ever happens to them, theyll send you a replacement set, logitech/apple great customer service, i also posted a few other priced ones if youre not looking for a huge set up:

Preventing Digital Audio Out from "Sleeping"?

I'm using the mid 2010 Mac Mini and digital audio out.
My receiver is showing the loss of digital audio signal when the mini hasn't played a sound for awhile and then comes back when audio is played.
I loose about 1 second of audio though when this happens which is bad for quick sounds. Subsequent sounds play fine until it "sleeps" again.
In Windows it keeps the digital signal live at all times which is what I want in Snow.
Is this possible?

You should only experience a delay when you switch to a new source of sound. Such as first starting playback in itunes, or first start Pandora, or just starting to watch a video clip.
This is because OSX typically only outputs a digital bitstream when there is an actual audio bitstream source currently "playing."
I regularly see my Denon receiver indicate a loss of the audio bitstream and then indicate when it starts up again. I have not experienced a problem because of this.
I suspect your particular receiver is slow to respond to new bitstreams. I have two suggestions to help mitigate this:
First, it might help to lock your receiver to the optical audio input (for that particular source selection). Since the receiver is likely simultaneously monitoring the HDMI, coaxial and optical inputs for a new bitstream, this could cause a delay in its reaction to a new audio stream.
Also check the receiver's manual and see if there are adjustments for its digital audio behavior. Disable any buffers or processing effects or "enhancements."

Switching Core Audio Drivers - No Audio Out

I have a project in Logic Pro 8. It was recorded with Presonus Core Audio drivers on a Powerbook. The Project was then handed off to me to complete here in the studio.
I re-opened the Logic Express Project in Logic Pro 8 using Digidesign HD hardware and Digidesign's Digidesign HW (HD) Core audio driver. All was well.
We decided to try some changes in routing, using some new equipment M-Audio (ProFire Lightbridge) to take advantage of some Apogee I/O units in the studio. Loaded up the M-Audio Core Audio Drivers (ProFire Lightbridge Multichannel), made sure everything appeared properly in the Apple AMS (Audio Midi Setup) panel and did test tracks in Logic. All was well still
Then I opened the Project, which had been working in Logic 8 and interfacing with the Digi HD hardware, now using the Lightbridge Multichannel driver to access the Apogee I/O, and...no audio.
No indication of activity on the hardware interfaces. I checked Logic 8, onscreen everything appeared normal. Channel meter activity. Channel routing remained unchanged and should have appeared at the appropriate D/A convertor. Digital activity which would have normally been indicated at the ADAT to Firewire interface was non-existent. So, I would deduce that the computer was not directing the Logic channel activity through the new driver to the firewire interface from this project.
I rechecked the test project with tones. I/O activity normal. Audio out. I opened another of the series of sessions from Logic Express to Logic using DAE now using the M-Audio interface. Nada. No firewire/ADAT activity?
I have reverted without problem back to using the DAE/Digi Core Audio model with no problems, but I would like to get the ADAT/Core Audio model running on these same projects as a proof-of-concept, and see no reason why it shouldn't.
Opinions, suggestions, ideas, questions?
...JB

When I was on the phone with M-Audio Tech Support (they're quite helpful) we noted the following:
1. If you switch over to Core Audio using the Mac's Internal speaker in one of these projects (switch to Apple's internal Core Audio Driver). All Channels are immediately updated to show only Output 1-2 available. and the project plays through channels 1-2 and the MacPro Speaker.
2. Switching back to DAE Core Audio, all available channels are updated and all plays/records normally using the Digidesign HW (HD) Core Audio Driver.
3. When the ProFire Lightbridge Core Audio Driver is selected, all channels are updated (now 1-18) and available, but if you select a channel or channel pair on one of the Channel Strips that was not in use previously in this session, an "out" bus for that channel is not created in Logic (which it normally does, assuming you choose a new channel pair for output from a channel strip...)
When a 'new' project is created with the Lightbridge setup selected as the Core Audio output, all channels will auto create an appropriate channel output strip.
My problem only exists when opening a previously created project. (In this case using DAE Core Audio...and I'm not implicating that as the cause, I don't think it is.)
It's like having previous sessions/projects, buying new hardware to improve your ability to work with them only to find out you can't use your new stuff with the old sessions. (Not like that hasn't happened before.)
Either Logic is at fault, not being able to accomodate the driver change from DAE to M-Audio, or the M-Audio driver is, being unable to get Logic to update its Environment to accomodate the new channel availability.

HT2844 iMac 27"(late 2009), Audio in/Optical digital audio out port, stopped recognizing my new Bose speaker system, previously working...

Hello,
My iMac 27"(late 2009), Audio in/Optical digital audio out port, stopped recognizing my new Bose speaker system, previously working through that port. I tested the speaker system through my iPhone, and it works fine. I hooked it up to the Headphone out/Optical digital audio in port, and it works through that port also. I did a computer restart, I also checked all wiring and did a system repair on the computer. I also restarted the computer in mode where I could use the system utility, and the computer still did not correct the matter, and it reported everything as being "ok". I wented into "sound", through system preferences, and the computer does not recognize anything I plug into the Audio in/Optical digital audio out port. When I plug the speaker sysytem into the headphone out/optical digital audio out port, it does recognize the Bose speaker system as being "headphones".
Reading through a lot of forums, I hear everything from compatibility, to the port being stuck, and on and on. Since the port was working before, and just quit working one day, I wonder if there is a capacitor or fuse or some type of similar thing is blown, and causing the port to be unfunctionable. Maybe the port went bad, but before this time, I had never used it, and the computer does not move around, and I never plug in and pull wiring out unless needing to, and that being rare.
Here is a link to Costco, where I bought the system, and the exact system I have, if this is any help: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=bsd&cs=04&sku= A4092931&ST=pla&dgc=ST&cid=262075&lid=4742361&acd=1230980794501410
By the way, I am running OS X Mountain Lion (10.8.5). I upgraded to Mavericks about a month ago, and expeirienced a number of issues, and had to take my iMac into Apple. Talking with the tech, I decided to wait for a while more before I upgraded to Mavericks. I try and keep the computer maintained.
If any of you have any ideas regadrding wear and tear, and fix I can do, etc., besides having to take my computer into Apple? Thank you, and potentially all of you, for your time and effort in helping me with this issue. Thank you kindly.

Okay, davE, first, you have posted in the "Mac Pro" forum (not Macbook Pro), so we can't be super helpful
but we help you. First, hold down the Option key while clicking on the speaker icon at the top of your screen. This should show you all the inputs and outputs you have. you could check in "About this Mac" then "More info" to see whatever's recognized. Then, maybe, fire up Audio MIDI. your speaker system should show up there. something might have gotten set incorrectly. You can test it there. I guess you are using the good ol' analog cable for connection, and it works on your iPhone, so the cable isn't bad. You could try this. it 's an adapter which might solve your problem
http://www.amazon.com/gp/product/B004HBWYQ6/ref=oh_details_o00_s00_i00
depending on which model of Bose speaker you have, you might try doing a product reset
turn off speakers...unplug power cord from outlet...wait 1 minute..plug cord into outlet..turn on speakers..
\\turning off automatic standby||
press and hold top of control pod for 6 seconds until you hear 2 tones that go from high to low
other than that ,I don't know

Beginning of audio cut off when using digital optical out

Hi all,
This is my first post here since switching to Mac earlier this year.
I'm having problems with the first second or so of audio being cut off when commencing playback using the Mac's digital optical out. This happens with any source of audio in a variety of different applications (e.g. video, iTunes, even system sounds for notifications and the like). I have used a mini Toslink to Toslink optical cable to connect from the Mac's audio out jack to the receiver of my digital speakers (Logitech Z906). Once playback has commenced, audio plays fine; it's just the very first second or so which is usually clipped.
The problem does NOT happen when using the built-in speakers. I've also noticed that if I unplug the cable from the receiver end (leaving it connected at the Mac end) I can see the red LED light shining the optical signal down the cable, but this goes out exactly 30 seconds after audio stops playing. If I start another audio playback within 30 seconds, there is no loss of audio at the beginning, but if I wait longer than 30 seconds (i.e. after the LED has gone out) I encounter the problems with the initial audio being clipped. I therefore suspect that this is an OS issue which is shutting down the digital optical out when audio is not actually playing (presumably to save power or something). I wouldn't have a problem with this if it actually worked properly when audio playback recommences, but it seems that there is a slight delay whilst the optical out service 'wakes up' again and this is leading to the clipped audio.
I've done some searching of the internet (and these support communities) for this problem and there seems to be little information about it. It does seem to affect a few other people though and some have resorted to third party applications or scripts which play silent audio at regular intervals to keep the optical output running permanently (e.g. SoundStay (https://www.macupdate.com/app/mac/39833/soundstay) - no longer maintained and the download link is dead). However, these amount to a kludge at best which treat the symptoms rather than the underlying cause, which I would rather resolve.
I tried to log a support case with Apple in order to have them call me, only to have the system tell me that my support has already expired, despite having purchased the Mac only 4 months ago. It seems that my Apple One-Year Limited Warranty is actually only 90 days when it comes to telephone support. So here I am!
Does anyone else have this problem with optical out, and how can I resolve this? Any help would be gratefully appreciated.
Thank you.

Hello kcore66,
Would it be possible for you to upload one of the files in
question so that I can take a look. In Captivate 1.01 there is an
intermittent problem where sometimes the audio is either cut off or
just doesn't play when you publish / preview. To get around this
simply moving the audio object back and forth along the timeline
and then positioning it back in it's original position works 9
times out of 10.

Optical digital and analog audio out

I just purchased a Pavilion 500-214 with IDT High Def Audio CODEC / DTS Sound+
Is it possible to get both opitcal digital audio out and analog (speakers/headphones) out at same time? Stereo amp needs access to both for multizone/source function. I can manually pick one or the other before playback - it is clunky in that when switching audio out devices the active will turn off but one switching to does not always turn on. But i really need both simultaneously active for amp to work properly. I have also found rear speaker jack to be more stubborn during switching than front headphone jack.
This question was solved.

Hi zombi1,
Welcome to the HP Forums!
I have done some research on whether or not one can utilize both digital or analogue audio out at the same time, and unfortunately this is not possible.
Thank you for posting, and Happy Earth Day!

HT4806 Mac mini digital audio out through the headphone jack

I'm misled by this sentence for audio out port from the support page: "For digital audio, you can use Apple iPhone headset with microphone".
http://support.apple.com/kb/ht5539
It is there for all mac minis starting from 2010 model.
Does it mean electrical digital signal? Any chance to get S/PDIF coaxial signal?

If an optical signal is OK, you just need one of these:

To convert the optical signal to a co-ax one will need a more complex/expensive convertor.

Splitting digital/analog audio outs?

I'm wondering if there's a way to split the audio out of an Intel Mac Mini into both analog and digital outputs. I'd like both active at the same time.
I've got a Mini in my home theater rack now, which is great. To keep things easy to use for the rest of the family I have the audio and video going straight to the TV. The TV only has analog in for audio. But I also want to run optical digital audio to the receiver to take advantage of the big speakers when appropriate (not used every day).
Conceptually it might need just a splitter, but I've never seen such a thing.
Thanks!

I'm pretty sure you won't be able to do this in a trivial fashion. The mini will detect what you have plugged into it (analog or digital) and will only output the proper data.
What I have at home to work around this issue to route digital content to my 7.1 receiver yet stereo to my whole house cable channel is to take the digital out from my receiver and pipe it through a device that converts the digital signal to analog.
The only thing I've been able to find to do this for a somewhat reasonable price is the Thrustmaster. Its quite a hack as this is intended to be used with a set of headphones but it works pretty well.

Iphone digital audio out

Is there any way to get hold of the digital audio from an iPhone 4S without buying a dock? I was planning on getting an FiiO E17 portable dac/headphones amp, so keeping it portable, I wish for a simple solution which fits with this.

Yeah, Ive been looking at the pinout and Im guessing it is possible to get digital audio transferred through the usb pins, but how to initiate that? What protocol and what language? Or is there some simpler way to initiate audio out? Id really like something simpler than building my own controller box, but if that is what it takes, then...

DVD Digital Audio Out

I'm new to the Mac world, and I was wondering does DVD player in Mac OSX do digital audio out? I'm currently using a Dell XPS. I watch all my movies on it and it's connected to a surround system. When I play movies it sends the Dolby Digital signal straight to the Amp where it detects the digital signal and decodes it. Will this work the same way in OSX as long as I use the optical out on the Mac Pro?
Thanks.

The Apple DVD Player Software may need configuration in order to enable Dolby Digital 2 and DTS Passthrough. Otherwise you will only have 2-channel Stereo LPCM. While most Amps will be able to use Dolby Pro-Logic 2 to emulate Surround Sound, Dolby Digital 2 and DTS support 5.1 Surround Sound.
With your Amp connected to your Mac with an Optical Audio Cable, and no DVD in the drive, start up DVD Player.app.
In the "Disc Setup" Tab of DVD Player Preferences, select "Digital Out - Built In Output" from the "Audio Output" option.
You may have to reset this every time you connect or disconnect the Optical Cable, but the Improved Audio is worth it.

Digital Audio Outs not mentioned in manual.

I have a Pavillion p6140f PC. Below the monitor connector, above the mouse and keyboard inputs are "Digital Audio Out" RCA jacks.
My manual doesn't mention these, whatsoever.
I tried plugging them into my Yamaha mixer inputs with no success.
Is there a certain driver needed to operate these?
I recently reformatted the PC. It used to be Vista, then was Windows 7 Home and is now Win7Premium 64bit.
Any advice would be appreciated.
Thanks.

Have you plugged in the HDMI cable and connected it to a device such as a LCD display ot HDTV?
Have you set the input on the TV or display to Computer?
Have you checked in the Control Panel in Sound to see if it shows ready? ( that would mean you had successfully installed the driver for your notebook's display)
Does your notebook have switchable graphics or only the Intel Graphics Media Accelerator 4500MHD inbuilt video solution?
What is the installed operating system for your notebook?
