MacBook Pro :: After Updating To OS 10.7.4 Digital Optical Out Has Stopped Working?
Jun 20, 2012
I use a Toslink connection and iTunes to listen to music files through two different audio systems. After the latest OS update the digital optical connection has ceased to work. I've tried it with another computer running an older OS and it works fine, no issues on either audio system.Â
Has anyone else had this problem and found a way to resolve it? I've spent 2 days with Apple Senior Tech Support and it's still not working.

I've read several threads where people have been having trouble with this, but nothing has been resolved so far? I've got a 2ghz core duo mac mini running OS 10.6.4. I used to be able to stream digital output from it, but I cant anymore & it's driving me around the bend. I have tried new cables, different combinations of sources of audio, cables, inputs on my AV receiver and everything is in good working order apart from the digital out on my mac.
It will play analogue stereo fine, it will play from the built-in speakers, but it will not play the optical digital stream. As I said before, it used to do this fine, until one day it just stopped working, it kind of 'faded out' and never came back. The light still shines when the toslink cable is plugged in and the output switches to digital in system prefs, but nothing is being received by the AV receiver.

I have a western digital passport ehd with HFS+ formattnig on my mbp. It was working fine for months. I tried always to properly eject it, but occasionally I would meess up and improperly eject if like the HD fell off my lap and the cord came undone or something. Anyway, I think I really got myself in a pickle now. I was either downloading something and then forcequit which caused it, or restarted finder, or something where now my EHD is not even recognized. when plugged in to the usb it looks like it is recognized on system profiler as "vendor-specific" on disk utility it was recognized once and I didn't take the opportunity to try and repair, but instead tried to save data... bad move - now it doesn't even pick up on disk utility - just shows my internal hd. I tried resetting the PRAM - i don't know exactly what that does but I read I should try that somewhere.

My friend is looking into buying the new 27" iMac Core i7 to replace his PC desktop. The only thing holding him back is that he has an analog surround sound system he uses for his speakers. I am having a hard time myself finding a converter that can make his speakers work in the iMac's optical digital output port. Any products out there that will do that?

Since the new Air doesn't have optical digital out anymore I am no longer able to hook it up to my system to transport multichannel audio...Does anyone have a good solution that is buyable from Europe? I have bought 2 USB sound cards with optical audio out, but both are incapable of pass through so they are useless and going to Ebay.It seems they support HDMI Audio out, but is that not restricted to Stereo also (on the Air)? If it isn't it should be quite easy to get the two pins from the HDMI connector and get the digital signal onto a normal RCA plug, but then it still isn't optical and my whole system is based on optical toslinks

My sound card seems to be meesing up. It switches back an forth from "Internal Speakers" or "Headpohones" to "Digital Output". For some reason the optical source keeps getting flipped on and is really annoying. I tried blowing out dust to see if that was causeing the comptuer's confusion, but that didn't work. Until I can make time to go to the apple store, is there anyway for me to turn off that certain connection through terminal commands or something?

I installed 10.5.7 yesterday. Immediately after the installation was complete, my Apple bluetooth keyboard stopped working. Went into Bluetooth system settings, and it said that there was no bluetooth hardware found... (it's built into the machine!!)...
Also, every time I start iTunes, it gives some weird error about Adobe Flash player. I'm not at home now so I don't have the exact wording of the error with me, sorry...

I just picked up a new 1.83 core 2 duo at a price I couldn't pass up. I am going to use it as a HTPC so I have my hdmi cable, etc. All hooked up and ready to go. Last bit is the audio but I am having a bit of trouble. I bought a standard miniplug cable and assumed it would plug in just like my macbook. The problem is that the miniplug doesn't fit in the jack on the mini. I understand that the jack on the mini is a combo analog/optical jack but as you see below, it seems as though a standard miniplug y cable should work.
From the Apple support website:
The headphone / line output jack accommodates digital optical audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used.
For digital audio, a standard toslink cable with a toslink mini-plug adapter can be used.I have done my research and some reading and can go out and buy an optical cable plus a miniplug/optical adapter but would rather go the analog route (I understand the quality difference) because I already have the cables and don't have a receiver or speakers, just my tv speakers.

is there a sound card out there for a Mac Pro that supports 6 channel direct and digital optical? I know the current Mac Pros already support that but not 6 channel direct. !

I was in the middle of ripping a series of CDs in iTunes when the drive suddenly stopped reading the CDs' contents - I have tried several CDs, including re-trying ones I had already ripped. It does not get beyond track list. Do I need a new drive or can I solve it? I have also tried using a CD cleaning disc. 3 years old iMac with Mavericks installed, no previous problems. It still reads disc title and content list and loads / ejects correctly.

since 2 days my optical drive makes one very strange noise every time in "wake it up" or turn it on. The sound is done three times. I realized today that now I'm not able to put a disc into the drive, instead of "absorving" the disc, the drive expels it.

I have purchased a optical audio cable to hook up my 15" mbp to my LCD.One end is the toslink and the other end is the toslink adapter, when I put both end into its place. The speaker icon turns gray and I cannot adjust the sound level and the music stops from the laptop speaker.Also, the optical digital audio out option is not showing up in audio preference.

The sound output in my Macbook Pro has been going in and out now for a number of months. And yesterday it finally got stuck on "Digital Output" meaning when I take out headphones from the jack, the internal speakers do not work. I am planning on taking it in and wanted to know, since I am still under warranty will Apple repair it, or give me a new one?

It worked when we first bought the computer (a few months ago). I've updated the MacBook Air software and re-installed Lego Digital Designer and it still doesn't work.

I used to have a magic mouse connected to my mbp (mid 2008) it worked ok, until I updated to Lion.Same with the keyboard.Both appear to be connected ok via Bluetooth. The only functionality letf on the mouse is the scrolling up and down. The keayboard appears to be inoperable completly. What I did to cure the problem so far is:
- Reinstalling the OS (Lion) - no go
- Reinstall Leopard und run all updates, no go
- Zap the p-Ram and resetting the whole mbp.
- I checked the BT connection an setting and reinstalled the mouse a several times, no go.Â
Other Bluetooth devices work OK on the mbp.The mouse and the keyboard work with my Windows PC ?It looks not like a hardware issue, I just learned on the net, that there are more people with the same issue.Could a firmware issue be responsible for this?

I finally upgraded from my 15" PowerBook 1.67 to the new 13" MacBook Pro 2.66. On the PowerBook I would usually run an external display using a single link DVI cable. I have read about the issues with the apple mini display adapters not working on DVI-I or non fully digital displays, but since I had been running the external via single link DVI (digital correct?) I figured that I wouldn't run into any problems. I did some troubleshooting with what I had and plugged my computer into my TV through the mini display adapter to a single link DVI to HDMI cable and all worked fine. Do you think that a dual link DVI cable could solve the problem connecting to my monitor? Or is my monitor flat out incabable? Third party adapter? Worst case I could just go VGA, though I don't want to. My monitor is a Sceptre x20.

My headphone jack was working just fine until this morning when I opened my computer. It's plugged in, but the sound keeps going through the head speakers. I have done the system preference check to make sure it is not muted.

Not sure why, but all of a sudden have no sound effects. When I go to System Preferences all the alert sound effect choices are grayed out. When press the volume buttons, can't adjust settings and there's a strike-out symbol underneath the bars.

I plugged in the charger after not having my computer charging since the morning. My charger did not work and pluged it in to other sockets around the house. I then tried my sisters charger, which was working for her computer. The odd thing is that after I tested it on my computer it no longer worked for my sisters computer. This is so confusing and I don't want to pay $160 on two chargers.It is the L style charger and we have had both for about less than 6 months.
