No audio from my macbook pro

I've had a problem with my MacBook Pro (2008) for a while.
If I connect a headset or external speakers, there will be no sound from the Macs audio output. The built in speakers is working perfectly.
Do you have any idears what could be the reason? I tryed do reset the Pram but with no luck. If it helps there is no red ligt coming out of the macs output.
The problem occurred when I connected a mini-jack for my speakers.
Maybe the output thinks it's a S/PDIF and not a normal audio output?

Have you looked in System Preferences -> Sound? Perhaps mute is on sometimes. Remove your audio cable and then reinsert it to see what the Sound panel displays. May be helpful to know the cable and the speaker interface you are plugging in.

  • I recently purchased an Onkyo stereo receiver with a wireless USB adapter, UWF-1, and want to stream audio from my MacBook Pro through my stereo system. The receiver tells me it is connected to my wireless LAN, but I cannot get music to play?

    New to the community here, thanks for your patience.  I recently purchased an Onkyo TX-8050 Network Stereo Receiver with the UWF-1 USB adapter with the intent to stream audio from my MacBook Pro to the stereo. I have gone through the setup instructions for the adapter and the receiver gives me a message saying that it is connected to the password protected network, but that is as far as I can get.
    I have gone into iTunes and clicked on the "Open Stream" option, but I just get a pop up box labeled "URL" that is empty. I have Home Sharing turned on and File Sharing turned on, but I am not seeing the receiver in my Finder window or as a iTunes device.
    I would appreciate any and all advice and assistance.
    Thanks so much.

    So I have been searching the iStore for Airplay and I find lots of information about what it is, but nothing about how much it costs, how/where to buy it, etc.?
    Fortunately, AirPlay does not cost anything as it is a streaming protocol used by Apple. Currently, the AirPort Express and Apple TV are AirPlay-ready. A number of other companies, like JBL, iHome, Denon and Klipsch are also rumored to be working on AirPlay versions of their products.
    Your other option would be to get an AirPort Express and connect it to your Onkyo analog or optical digital audio input and stream from iTunes that way. I currently do this with my 10+ year old Harmon Kardon HT receiver.

  • Stream Safari/DVD audio from my Macbook Pro to my Airport Express.

    Is there a good way to stream all audio from my Macbook Pro to my Airport Express? Not just simply the iTunes audio.

    This does work in general but not for my particular need.  I have a Mac G5 using ProTools and a MBox digitizing vinyl (USB connection).  I am on a MBP getting work done elsewhere in the house, but want to listen to the music and especially to tell when album side is done.  To get music to the MBP,  I have plugged the G5's line inputs to the MBox line outputs, then used messenger to create a chat with the MBP.  Too bad I could not get the G5's input to be the MBox, but ProTools wants sole control.  Works OK, but the messenger output on the MBP will NOT go to the Apple Express, just the speakers or headphone out jack.

  • How do I get audio from my macbook pro to my receiver with higher quality than the headphone jack?

    I recently got a receiver and surround sound speaker system.  The quality of the audio from the CD player connected to it is far beyond the quality of the audio that comes from the MacBook pro via headphone jack to RCA connection.  This was confirmed by burning a CD from the MacBook, placing it in the CD player then testing the two against each other  -  the same audio piece from the CD player or the MacBook, both connected to the same receiver/speaker set up.  What other options might get better audio quality from the MacBook to the receiver? 

    The Mac's audio output doubles as a optical Toslink stereo mini jack, just use a adapter to regular Toslink and plug the optical cable to your surround sound system. Fiddle with the sound settings to enable optical output.
    Mac's pass surround sound through, they don't do any processing.

  • How do I hear audio from my Macbook Pro 2009 to my LED TV?

    I recently received an adapter for my Macbook Pro 2009, Mini DisplayPort (Mini DP) to HDMI Female Adapter + HDMI Cable for my birthday.  I knew before receiving this adapter I needed something to transmit audio to my TV.  However, th 1/8' (3.5mm) to RCA stereo audio cable I purchased does not work. Does anyone have a suggestion on which cable I need to purchase next to make the sound component work when connecting my laptop to my Toshiba LED TV?

  • Transferring audio from my macbook pro to iphone 3g

    I'm trying to create a voicemail box for my customers to call for monthly info and I want to include a song in the message (greeting). This sounds awful just holding up the phone to the computer so I was wondering what cable exists that will allow me to go from the macbook headphone jack to the iphone headphone jack and accept audio. I tried using a standard 1/8 male and of course that didn't work.
    I perused the internet for about an hour and gave up.
    Thanks for any help you can provide!

    Ahh OK I understand, no the headphone jack on the iPod is output only, the iPhone ear buds have a microphone on but that won't work with an iPod as far as I know. I think your best bet is to just cue the track on the Mac and at the right time play it back while holding the phone near the speaker ...

  • Trying to connect a Belkin brand audio cable from my MacBook Pro to a Sony flatscreen TV. Cannot get any sound from the laptop out of the TV. What am I doing wrong?

    I'm trying to connect a Belkin brand stereo audio cable from my MacBook Pro to a Sony flatscreen TV (Apple "genius" handed me the cable to purchase.)  I have tried all the ports in the back of the Sony, and tried the volume on both the cable and TV remotes. I cannot get sound out of the Sony from my MacBook Pro laptop. What am I doing wrong???

    Downloaded your operating manual.  It appears that you need to connect the HDMI to HDMI 1 and the audio to the input socket just to the right of the VGA socket (i.e., between the VGA and the RF input connection).  The picture on page13 seems to be the clearest I could find:
    Although it's not exactly clear I think they are talking about a standard 3.5 mm (1/8") stereo jack for the audio inpu as opposed to the more common RCA jacks used in the row just above that VGA input socket.
    I haven't checked the manual as yet whether you need to set anything special with the controls other than input select.
    Note, if that truly is a 3.5 mm stereo jack cables are very common.  In your case it would just be a cable with a 3.5 mm jack on each end.
    Update:
    You will have to experiment with this but I think you will need to try pusing the input button to select either HDMI1 or PC (or Component?).  The manual is not clear on this (page 31).  Sometimes it just comes down to pushing buttons.

    I can hear a loud 'CD spinning/fan like' sound from my MacBook Pro intermittently. Definitely not the audio as i muted it. No CD either. And the only programs running are words, safari and mail.

    It sounds like the fan but this is the first time I hear it in the past 6mths using this Mac. If its the fan, shouldn't the sound be there all the time and not intermittent?

  • Really weird noise is emitted from my MacBook Pro audio out

    When using my audio output from my MacBook Pro the weirdest thing happens. I use software called MacsCue which I had previously used on my PowerBook G4. If no music has played from the audio output, it seems the computer needs to activate it and it emits a loud noise before playing the audio. As this is hooked up to a live system, it is unacceptable. After 10 seconds of not playing any audio, the jack will emit some staticy interference until I attempt to play something again. This is ridiculous. What should I do?

    then its still under warranty.  Call AppleCare or visit your nearest Apple store or AASP.

  • HT3382 Connect from a MacBook Pro's mini display port to a Display Port monitor?

    Hello everyone,
    Is it possible to connect from a MacBook Pro's mini display port to a Display Port monitor with resolutions higher than 1920 x 1200? It seems Apple does not supply a mini-DP to DP adapter.
    However, just as they do not make a mini-DP to HDMI adapter, but they do recommend a Belkin product for this purpose.
    Is there any reason that a mini-DP to DP adapter or cable wouldn't work and support high resolutions?
    Thanks for your feedback!

    Hey tjk,
    Thanks for the response.
    Do you have any recommendations for a potential set up? The audio output and Apple DVI are on different sides of my MBP, which is alright, I guess I can get two long cables to handle each. I was hoping to just have my MBP closer to where I use it, with a cord nearby plugged in on one side to the HDTV and resting near where I keep my MBP for when I want to use the HDTV as an external monitor.
    With a converter like this, you can run video out of the MBP's DVI port, and miniToslink (optical) audio out of the 3.5mm stereo mini jack to the converter, then it will combine the two and output audio and video through HDMI to the monitor.

    Otherwise, depending on the TV's inputs, for video you could run DVI to DVI on the TV, or DVI to HDMI to the TV. For audio you could run 3.5mm stereo mini plug from the MBP to RCA adapter on the TV. Toslink/optical is also an option.

    When I purchase music through iTunes from my MacBook Pro, my iPhone 4 iTunes app cannot detect those purchase to allow them to download to my phone. If I open up the iTunes app and select "purchased > music > not on this iphone" it tells me "All of your available music has been downloaded to this device." However, my purchases are not yet downloaded to the iphone and not available to download. If I go to "purchased > music > all > recent purchases" it will show me the purchases that were most recent the last time I synced my phone, but not the purchases since then.
    Any thoughts on how I can remedy this and make all of my purchased music available on my phone without requiring syncing?

  • How do I play video from my macbook pro to my tv?

    How do I play video from my macbook pro to my tv?

    What model MacBook Pro do you have? On my late 2011, I used to use a Mini DisplayPort/Thunderbolt to HDMI adapter to get video and audio from my Mac to my television. I used this adapter from Monoprice. Worked great - I just no longer use it because I bought a 27" monitor.
    You can also use AirPlay mirroring if you've the right MBP and an Apple TV - but the wired method works, too.

    How do I stream rhapsody from my MacBook Pro to my receiver with Airport Express?

    You will need an application like Airfoil for Mac to be able to stream any audio files on your computer to the AirPort Express.

  • Cable that will connect to a VGA port on a TV from my MacBook Pro (2.4GHz Intel Core 2 Duo)

    Hi,
    The HDMI port on my Maxent tv is not working.  I am hoping to connect my MacBook Pro to the TV via the VGA port on the TV to watch Netflix and movies.  What cables do I need that will connect to a VGA port on a TV from my MacBook Pro (2.4GHz Intel Core 2 Duo)?  And will that cable support audio or will I need a separate audio cable?
    Thanks-
    Sheri

    Hi Sheri,
    The Core 2 Duo MacBook Pro models have a Mini DisplayPort for video out, which can be connected to a VGA connector using Apple's adapter. See this product page -
    Mini DisplayPort to VGA Adapter - Apple Store (U.S.)
    VGA does not carry an audio signal.
    Thanks for using Apple Support Communities.
    Best,

    QuickTime Pro costs a few buck but is a good tool to have on hand as it can open and transcode a wide variety of video and audio formats.
