Optical digital audio out?

does any one have optical digital audio out to a receiver working? it doesn't work for mp3 through itunes, video purchased on itunes, cds or dvds. works fine with the same setup and a previous generation macbook so i know it's not the receiver or cable.
my fear is that this is a defective design issue related to the displayport hdcp issues. hopefully, my hardware is just malfunctioning.
i was on the phone over an hour with apple troubleshooting, but no one had an answer to the hdcp question.
thanks.

i took my macbook up to the apple store to the "genius bar". after a few minutes, they just decided to replace the entire macbook. fine. after i got home, i immediately tested the digital out port. it works! fantastic. unfortunately, throughout the course of the night i continued setting up the new macbook. i later try the digital audio out and now it's not working.
this morning i'm trying it again and it's working, briefly. i've found that by moving the cable around near the output jack that the sound will come and go. i tried a different cable with the same results. although it seemed to work less frequently. both cables in different devices (including a previous generation macbook) work fine.
i've also noticed some of the comments on this forum and others (i think they were referring to different notebook models) about people having problems with the internal speakers not reactivating after unplugging headphones. my guess now is that the headphone jacks are just poorly designed, manufactured or i'm just unlucky.
i would think it's definitely not an hdcp or other content protection issue.
i guess i could exchange for another macbook, but with 2 having this problem it's seeming less likely another one will work out. i guess i could just be really unlucky and maybe 3rd times a charm. my only other alternatives as i see it are returning it or just living with the digital audio out not working (annoying, but everything should work on a $1500 laptop).

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

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

Optical digital audio out so good you don't need external audio card?

IS the optical digital audio out of the MBP so good you don't need an external audio card?
I was looking into buying the MAUDIO mobilepre to connect my soon to be received MBP to the speakers, but the Apple rep told me the new optical digital connection is good enough that i can bypass an interface card. Is this true?
For reference I am planning to buy the EDIROL DM20 as monitors to edit audio in FCP 5.
Thnak you for your feedback

I'm an audiophile as well. I wouldn't use the MBP headphone out to drive a serious audio system, so I don't disagree with your use of a good external DAC. But the poster wants to drive speakers that take digital input. So the question is about the digital output, not the DACs. Given the equipment he proposes to attach, I doubt there's any justification for using an external device to generate the digital out.

Optical digital audio out port

Here is the situation:
The only problem I have with my Mac Pro is that the Audio line-out port does not work reliably in Boot Camp. The audio output cuts out easily and then I have to "jiggle" the speaker cable to get the sound back. And I have determined that it is the audio line-out port that is at fault, not the speakers, nor the cable.
So I want to try to work around this by utilizing the optical digital audio out port.
But I don't understand how it works.
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?
Thanks

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

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)

Optical digital audio out - can I keep the light on?

I have my iMac hooked up to my Sony receiver with a TOSLINK optical cable.
I have noticed that the Mac shuts off the signal light if there has been no audio output for 15 seconds. My Sony receiver then goes into a sort of standby mode. When the iMac again outputs digital audio, it takes about a half second for the receiver to wake up from standby mode. So the first half second of any new audio output is clipped. This means that short things like alert sounds, trash empty sound, etc are not heard at all if there has been no other sound output for the last 15 seconds.
If there is a way to keep the light on all the time, then my receiver will always "hear" and output everything.
Is there anyway to do this? I have thought about making a ten second audio clip of silence, and having QuickTime or some other program continuously loop it. But there has to be a better way to keep the light on.

Answered. My latest Google search was successful.
I found a launch agent that uses the "say" command to "speak" a single space every 10 seconds. That keeps the audio system alive, and keeps the light on.

Optical Digital audio - No output control

I'm trying to use the optical audio output on my late 2006 Mac Pro 1,1 (A1186), but no audio signal is received by my Sony audio amplifier even though the "Optical digital audio out" port and my TOSLINK cable show a red glow,
System Preferences says: "The selected device has no output controls." That same message has been displayed for Sound > Digital Out ever since my Mac was new, but this is the first time I've wanted to use that sound output.
Did my Mac Pro come with the needed controls? If "yes," how do I activate them? If "no," where can I obtain them?
Thanks for any help or suggestions!
Don

yep-try looking under system preferences-->sound--or fire up Audio Midi Setup and see if you can get it switched over that way. Dunno about your reciever. You may have to switch it over to digital on that input. I'll turn it over to someone more capable than me at the moment. Gotta go

CD player Toslink optical out to optical digital audio in port. Need help

Hello,
I'm taking the Toslink Optical out of my Sony 707esD CD player into the Audio in/optical digital audio in port of my March 2009 iMac.
In System preferences>Sound>Input>Digital in Optical digital-in port I see a signal occurring on the input level meter but I do not hear audio.
Output is headphones port and is working fine from other sources.
I see a signal input does anyone know how to hear the output.
Thanks.

TS5150 Does the optical digital audio port send out a Dolby Digital signal

Does the optical digital audio port send out a Dolby Digital signal

Yes if the media has such an audio track available it can do so.
There is a setting for audio and video allowing DD output to be set for Auto (on/off if connected HDMI device can decode DD), On or Off.

Optical digital audio output/headphone out

Does anyone know if there is a way to connect stereo speakers directly (not through a receiver/amp)to the Optical digital audio output/headphone out on a imac? The new 20 inch imacs have a 24watt internal amp which would be plenty for the speakers that I want it to drive. Thanks

is there an attachment that i have to buy? do i just rip the tip of the cord off?
Yep, there are two "standard" optical-digital-audio connectors -- the original "square" one is still used in most larger audio/video components. The newer/smaller one, used mainly in portable gear, is exactly the same size as a mini headphone plug. Radio Shack carries adapters/converters and cables of both types (usually at outrageously high prices). For online vendors, try:

Great prices and a good rep for quality/service among to the HDTV-fanatics on avsforum.com.

On all but the earlier Mac Pro models, this has been standard since the iMac G5.

These are now mini-Toslink.

Combined optical digital audio output/headphone out

What is the "combined optical digital audio output/headphone out"? This is what the output is called that has the earphone picture beside it on my MacBook. I thought this meant that it could take the mini jack out that splits into a/v - yellow, white, red, and plug it into any tv or monitor that has those inputs. I tried it just now, but a no go.
If the only way to get video is through the mini DVI output what does the "Combined optical digital audio output/headphone out" mean? If I can get video out of it, how can I do it?
Thanks!

Hi Trevor Deck: As you have discovered this does not output as a video signal. That jack is strictly for audio. The "optical" portion of it is used to output using a "Toslink" cable to provide "optical audio" to an external amplifier. The DVI port needs to be used to get a video signal to your TV. But be warned if you use the red, white, & yellow method of hooking up the video signal you will probably be disappointed. If your TV has a HDMI or PC input it would be much better. You would then have to get the proper DVI to whatever type adapter.
Good Luck

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.

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.

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."

Combined optical digital audio port

Combined optical digital audio input/audio line in (minijack)
Combined optical digital audio output/headphone out (minijack)
Dumb Question but what exactly does this mean, what types of connections does this port take? only headphone jack?

It is a jack that does both standard analog, and optical digital, on the one connection.
You can plug in a standard mini-headphone (1/8") like most iPod/music devices use, including 1/8" to two cable Y adapters for plugging into stereos, etc.
You can also buy a funky adapter that looks like a standard mini-headphone adapter, but it is plastic and has an optical jack on the back where the cable would usually be. This allows you to connect the MB digitally to any equipment (like a home stereo receiver) that accepts optical input, or plug things like CD players, DVD players, etc. into the MB's input. If you check out the online Apple Store, they sell a Belkin kit that has the adapter with a short optical cable and they have a picture so you can see an example.
