No digital audio signal over SPDIF auido out (MacBook Pro, Snow Leopard)

There is no audio signal over optical cable.
I have a standard toslink cable with a toslink mini-plug adapter for my macbook pro 15 2009 unibody.
The interesting thing is when I boot in Windows side it works fine, I hear sound and I see Dolby Digital or LPCM logo on my receiver, but when I reboot to Mac side then is gone.
Any ideas?

Have you opened up the MIDI audio setup program and checked the configuration there?

  • Hi, i forgot my macbook pro(snow leopard) password and i tried to reset it through single user mode, but whenever i type, everything comes out in CAPs instead of lower case. Each time i press the minus(-), it always comes out as an underscore(_).Pls help.

    Well, you can try easing the shift key up with something thin but flexible (credit card sort of thing) but if the contacts below are stuck you may need to get it seen to by an authorised repairer.
    If you can borrow a keyboard (a PC one will probably work as long as the password is alpha-numeric with no special characters) you can at least get in to backup your HD before going for repair.

  • Enabling Simultanious Analog and Digital Audio Signals

    My apple TV runs through a Yamaha receiver. It is hooked up with component video and digital audio cables. I also need to hook analog audio to my receiver so it can play outdoor speakers through zone 2 (which only recognizes analog signals). Zone 2 does not work when I hook both digital and analog cables. Called Yamaha and they said to look for a setting on Apple TV that enables simultanious analog and digital audio signals. Does anyone know if/how this can be done? Or any other way to make the analog zone work without losing digital on the main zone?

    AFAIK, the analog audio on the ATV outputs all the time. The audio output setting in the ATV just determines whether the digital output is Dolby or PCM. Try turning off Dolby in the ATV audio settings and see if that makes a difference. If not, the problem is probably elsewhere.

  • HT3625 Audio line function not available on Macbook Pro mid 2012

    Does Macbook Pro 13 inch (Mid 2012) with OSX Mountain support Audio line?  Its seems that OSX Mountain Lion disabled audio line in function in headphone port. This is a bad move by Apple because I am sure that everyone would like to use line in to record audio from external source.

    I am trying to connect an external audio source (line in) to a MacBook Pro 15" (Retina, Mid 2012). The built in phones port does not accept input signals (@Branduan: I can't confirm that itis a dual in/out port). I attached an external soundcard (M-Audio Fasttrack USB), but no signal made it into the MacBook Pro.
    Any chance how to get an audio signal into that machine??

    1. I ran software update and am up to date. Does this mean that my yet to be activated Boot Camp ap is also up to date?
    There are 4 confusing pages of updates listed at Apples website for Boot Camp. I am having a hard time understanding what I need and don't need. For example, what version of Boot Camp do I have? I have Boot Camp Assistant version 3.0.4. Does this mean I have Boot Camp ver 3?
    You have Mac OS X Snow Leopard, so you are going to use Boot Camp 3 on Windows. After installing Windows 7 on your MacBook, insert the Snow Leopard DVD and install the Boot Camp drivers from here. Then, as the Boot Camp drivers that your Snow Leopard disc contain are outdated, open Apple Software Update on Windows to install the most recent Boot Camp drivers.

    2. The printed Boot Camp instructions do not explain the process of using downloaded Windows drivers; the instuctions only refer to drivers on the original disks. I have the original install disks from around mid 2010 but I am sure many things have been updated by now. Wouldn't the best idea be to download and install? But the instructions only cover using the original disks. How do I use downloaded drivers?
    On Snow Leopard, you can only download the Boot Camp drivers for the Late 2010 MacBook Air. On Lion and Mountain Lion, you have to download the Boot Camp drivers for all the computers. If you try to download the Boot Camp drivers on Snow Leopard with your computer, you will get a message telling that there aren't any drivers to download for your MacBook Pro

  • Maxed out MacBook pro or Mid level MacBook pro with Retina?

    I am entering my first year in university in the next couple weeks. I am going to be studying commerce for the next 4 years. I want a macbook that will last me for the 4 years and still be a good product at that time period. Now I am wondering if I should spend $2000  on the maxed out MacBook pro or 2600 for the midlevel MacBookmacbook pro with Retina display. Looking forward to great feedback. Thanks

    It depends on how far you want to go - and how much you want to spend - in maxing out the computer. Let me visit the Apple Store -
    The 'base model' you should go with is the:
    15-inch: 2.6 GHz
    2.6GHz quad-core Intel Core i7
    Turbo Boost up to 3.6GHz
    8GB 1600MHz memory
    750GB 5400-rpm hard drive
    Intel HD Graphics 4000
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory
    Built-in battery (7 hours)
    This will be a 'stock' item and has the maximum amount of RAM that Apple will install and is $2,199. The only modifcation to make on this model is the CPU and hard drive, as it also comes with the maxed out VRAM for the NVIDIA graphics card. I wouldn't go for the extra speed bump on the CPU - it's just not worth it. What is worth the extra money is an uprade to the hard drive - from the 750GB 5400-rpm to the 750GB 7200-rpm for an extra $50. If you really want to max it out, of course, you could add the $900 option of the 512GB SSD, but I wouldn't do that - simply too much to pay. So for $2,249 you could get:
    15-inch: 2.6 GHz
    2.6GHz quad-core Intel Core i7
    Turbo Boost up to 3.6GHz
    8GB 1600MHz memory
    750GB 7200-rpm hard drive
    Intel HD Graphics 4000
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory
    Built-in battery (7 hours)
    ...and have a very fast (not warp speed, but fast) computer that should you ever decide to upgrade, you can.
    As for the Retina display, it's simply something that I would not invest in at this time. The 'base' model, with only 8GB of RAM is $2,799.00. Increase that RAM to 16GB, and you're looking at $2,999. The extra $750 just isn't worth it. And with few applications taking advantage of the Retina display (if they ever do) you're going to be looking at pixelated tools, text, etc., for who knows how many years. You could get by running only Apple applications, I suppose, but I'm just not ready to be placed in that kind of restrictive mode... are you?
    Just my 2¢, again...

    Anyone out there purchase Snow Leopard shortly before Apple's offer to get it free? I want to get a refund and purchase Lion so that I can use iCloud.

    You have to buy the DVD for 10.6. It's not available for download like 10.7.or 10.8. The 10.6 Snow Leopard DVD is in the Apple online store. You can get it for $19.99. You will need to be running 10.6.8 to access the App Store to order Lion or Mountain Lion. http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
    System Requirements for 10.6:
    Mac computer with an Intel processor
    1GB of memory
    5GB of available disk space
    DVD drive for installation
    Some features require a compatible internet service provider: fees may apply.
    The Early 2006 model 1,1 Core Duo can only run a maximum of 10.6 Snow Leopard. 
    The models Late 2006 Core 2 Duos 2,1 through Early 2008 4,1 can only run a maximum of 10.7 Lion.
    The Late 2008 model 5,1 Aluminum Unibody through the Mid 2010 White Unibody model 7,1 can run 10.8 Mountain Lion.

  • Can I import .cda audio file in iTunes on my Macbook Pro with OS X Yosemite

    Can I import .cda audio file in iTunes on my Macbook Pro with OS X Yosemite

    iNads,
    .CDA files are simple index files, less than 1 kB in size, that do not contain any audio.  There is no reason to import them.
    If you have the physical CD and wish to rip it into iTunes, you can import it per this guide:  iTunes 12 for Mac: Import songs from CDs

  • MacBook Pro running Leopard has suddenly thinks audio CDs are blank.  Also not recognized in Itunes.

    MacBook Pro running Leopard has suddenly thinks audio CDs are blank.  Also not recognized in Itunes.  What should I do to determine whether it's a hardware or software problem? Or is there something unusual about these CDs?

    I have the exact same issue.DVD's work perfectly, but audio cd's have stopped working.  I think it's pretty recent, but can't confirm it because i don't use audio cd's daily. So I think it might be software related instead of hardware related. I Have a Macbook pro 15" mid 2009 running the latest OSX release.

  • MacBook Pro and Leopard knock out my wireless network

    I am new to Mac, just having purchased the MacBook Pro with Leopard 10.5.1. installed. I have a Netgear WPN824 router that works perfectly with windows based computers. I use WEP 64 bit security. The MacBook connected with no problem and surfs the web fine until I try to download certain files on the MacBook (such as the HP drivers for my all in one printer) or try certain video feeds online , such as a cnn video. The download not only stops midstream but actually knocks out my entire network causing me to have to unplug my cable modem and router and restart everything. This is a real problem. Does anyone have a clue why this is happening? I can download the same files on a Windows laptop with no problem. Help.

    Hmm. It might not be the MBP. Are you using Safari? I've noticed that Safari at times is incompatible with many websites. Try downloading Firefox and try the same downloads.
