HDMI Audio through Mini Displayport?

Hi all
I've just ordered a mini-display port/HDMI adapter that supports audio which I assume would work on my 13"MBP. However I have just been looking at a few pages on the net that put me in some doubt. My MBP was purchased mid May 2010 and I was told in the Apple store at the time that it was the latest model, just in, as the line up was revised April 2010? But there appears to be a lot of confused surround it and if it supports audio via the mini-display port.
Can anyone confirm the functionality on this model?

Yes, the MBP 7,1 supports audio via mini-Displayport, so assuming your adapter also supports audio as advertised, it should do what you bought it for.

  • Audio through mini displayport

    I have a MacBook Pro Mid 2009 with Mini Displayport.  I want to use this to play Hi-def video and surround sound audio on my HDTV.  Can this be done and if so, how?

    Apple's Mini DisplayPort only started supporting audio out on the 2010 machines. So yours won't push audio.

  • Audio through Mini Displayport (HDMI Adapter)

    I'd like to connect my MBP to my amp using a HDMI adapter. Will any audio pass through this? Enabling a 5.1 output?
    Cheers

    Okay, now I'm confused. I always understood the digital audio limitation on the mini display output to be the result of stepping it down to DVI before bumping it back up to HDMI with an adaptor. Unless there's a mini display-to-HDMI option AND the mini display port is wired for audio, I don't expect anyone will be making a single-port, single-cable solution anytime soon.
    In any case, that's not what caught my attention on this thread... I'm still trying to get dolby 5.1 (i.e. AC3 passthrough) to work +at all+ on my audio output with a Toslink adaptor and Quicktime/iTunes. I've noticed that Plex passes AC3 bitstreams over the Toslink without any issues, so I know it's not an Apple hardware limitation. I just don't want to use Plex to watch my movies in 5.1
    I've messed around with the output settings nine ways to Sunday, but it's obvious the downconversion to digital stereo is happening in QT long before it ever gets to the hardware. Has anyone heard a good reason yet why AC3 passthrough was disabled in Quicktime and iTunes? It used to work.

  • MBP 2009: Audio over Mini DisplayPort

    Hello
    I previously ordered a Mini DisplayPort -> HDMI cable (http://www.amazon.co.uk/1-8m-DisplayPort-Adapter-Unibody-MacBook/dp/B003WVC8R2/r ef=sr1_fkmr01?ie=UTF8&m=A1T39SA8AUFT6J&qid=1289477962&sr=1-1-fkmr0).
    It's been working great with my 2009 model MacBook Pro, however I have to use a separate cable for audio.
    When in the Apple Store recently to fix a battery problem on that laptop, I got into a discussion about audio through HDMI on this model. According to the Mac Genius audio through Mini DisplayPort was enabled on older devices through a firmware update (and he said his Mac Mini now uses one cable to do audio and video).
    Audio is not working with the cable above - but was I incorrectly informed by Mac Genius, or do I need a different cable that does support audio?
    Thanks
    Jamie

    All we know about your MacBook Pro model is that you've identified it as a "2009 model MacBook Pro." Apple introduced audio-out via mini-displayport in the April 2010 MBP models, so if yours was bought before then, it didn't have that capability when it was new. To the best of my knowledge and belief, nothing that has happened or been released since then has changed that.
    [This article|http://support.apple.com/kb/HT4241], updated in June 2010 (after the release of the latest mac Mini), lists the Mac models that supported audio via mini-Displayport at that time:
    "iMac (Late 2009), MacBook Pro (Mid 2010), MacBook (Mid 2010), and Mac mini (Mid 2010) supply multichannel audio (up to 8 channels) and video signals over Mini DisplayPort."
    I haven't heard of any update that has changed that list since then. If it were possible to enable audio output by means of a firmware update, I think Apple would have made that update available to all owners of mini-Displayport-equipped Macs, not just some of them.

  • Have I power down Macbook and monitor (or TV) before connect (or disconnect) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter?

    Can I hot plug monitor (or TV) through Mini DisplayPort to DVI (or Mini DP to HDMI) Adapter? Or  I have to power down all before connect/disconnect through Adapter?

    Thank you, Mario.
    I just wanted to be shure because previously i destroyed two videocards on my pc by plugging hdmi without power down.

  • Does my MacBook passes audio through Mini Display Port or not?

    I recently bought a Mini DisplayPort > HDMI adapter in order to display my MacBook on my TV. Other users of the same adapter publicly stated that they got video AND audio out, but I got only video.
    I've been searching this online for two days now and I still don't know why (I even searched this support forum, but I must admit that I got a little lost and decided to write my own topic). All I discovered was that some MacBooks have this capacity (to port audio along with video through Mini DisplayPort) and others don't.
    I'm using a white MacBook unibody bought new and latest on late 2009. It's the first model with multitouch trackpad and without FireWire port. Its model name is "MacBook 6,1", I guess.
    Does anybody know for sure if It CAN, in fact deliver audio+video through the Mini DisplayPort if I'm using a compatible HDMI adapter?
    Thanks.

    These models pass audio through the display port:
    iMac (Late 2009), MacBook Pro (Mid 2010), MacBook (Mid 2010), and Mac mini (Mid 2010) supply multichannel audio (up to 8 channels) and video signals over Mini DisplayPort. To connect your television or other HDMI devices to your Mac, use select third-party Mini DisplayPort to HDMI adapters that conform to the VESA v1.1a DisplayPort Interoperability Guidelines. The following adapters adhere to these standards:
    - Moshi Mini DP to HDMI Adapter with Audio Support
    - Griffin Video Display Converter (Mini DisplayPort to HDMI and DVI)

  • MBP Audio over Mini-Displayport

    Hello
    How do I tell if my MBP can support audio over mini-displayport?
    I have purchased a mini-displayport to HDMI adapter but when I connect it to my TV I don't have the option in audio to choose the output over mini-displayport.
    I don't know if it is the adapter I have purchased preventing it from working or if it is the laptop.
    My MBP details are as follows:
    Model Name:    MacBook Pro
      Model Identifier:    MacBookPro5,1
      Processor Name:    Intel Core 2 Duo
      Processor Speed:    2.53 GHz

    MBP's like your late-2008 model don't output audio through the mini-displayport — the first models to do so were introduced in April 2010.
    You need an adapter like this:
    http://www.cablematters.com/pc-56-26-mini-displayport-male-and-toslink-audiousb- male-to-hdmi-female-adapter.aspx
    or this:

    The former carries 5.1-channel digital surround sound from the headphone port; the latter carries ordinary stereo from a USB port.

  • IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

    I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
    iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
    Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
    I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
    My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
    Thanks!

    I've tried a few times and it hasn't worked so far...
    23" Cinema Display (ADC) connected to Apple's ADC to DVI adapter/power box then connected to Apple's DVI to mini Display Port adapter.
    Trying to output extended desktop from iMac to 23" Cinema Display.
    No signal or anything on the 2nd monitor so far.
    USB port on Cinema Display works with the setup.
    Checked system updates and all up to date as of 01-10-2010.
    OS X 10.6.2 build 10C2234

  • No audio out through Mini Displayport?

    Last night I hooked up my first-gen MBA to my plasma TV using a connector that converted the Mini Displayport to HDMI. The movie I streamed from Netflix looked great. One problem -- no audio. I guess there's no audio out through the Mini Displayport? I was forced to hook up computer speakers to my MBA. Is there a way I can get audio to go through the Mini Displayport rather than the audio-out/headphone jack?

    There are a couple of adapters out that will convert DVI plus optical audio to HDMI (with audio). They are all made by the same company (though they are branded and priced differently). I think they are currently running around $100. The problem you might run into is HDCP. Apple doesn't do HDCP with their DVI... so you'll end up not having a compliant HDCP chain... if that is important to you.
    If you do this setup, make sure you have your TV set to a setting that is pixel to pixel... that is, doesn't adjust for overscan. Lest you loose some of your computer desktop.

  • No audio via Mini DisplayPort to HDMI Adapter

    I have a late 2008 model (MB470LL/A) 15" MacBook Pro running 10.6.7.
    I purchased a Dynex Mini DisplayPort to HDMI Adapter that's not picking up the audio signal. The video plays  fine via HDMI to our TV, but no audio.
    In looking online I've seen this is a known issue. Has anyone discovered a work around other then running a separate audio cable from my computer to the TV?
    I'm really surprised there is no audio this way. Someone dropped the ball on this one.

    I might be wrong but the MBP 2008 does not have audio supplied capability over MDP to HDMI.

  • HT3131 how do i get audio from my HDTV when using a hdmi cable and mini displayport??

    How do I get audio to display from my HDTV when I'm using a hmdi cable and a mini-displayport adapter on a macbook late 2008??

    The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.
    With the Late 2008 model 5,1 Aluminum Unibody there is an adapter that uses the Mini DisplayPort and a USB port to combine video and audio to HDMI. It's only 2 channel stereo not 5.1 Dolby Surround.

  • Mini displayport to HDMI = fine. Mini displayport to VGA = terrible on late 2011 MacBook Pro. Any ideas?

    Hello,
    I have a late 2011 unibody MacBook Pro. It has a real problem displaying through a projector or tv using mini displayport to VGA. I connect it to my tv at home with a mini displayport to HDMI cable and it works fine. If I have to connect through a VGA adapter/cable to a tv or projector for work the image always looks like the contrast has been turned right up and it looks awful. I have tried creating a profile, calibrating the secondary display and adjusting gamma settings but it doesn't make any difference.
    If I plug my old black MacBook into the same projector/tv using VGA it works fine so I now have to take 2 laptops to work which is ridiculous. I thought it might be the adapter itself but at a recent event a colleage experienced exactly the same problem with his identical set up so I thought it might be something to do with the projectors set up at the event but I recently tried connecting to a projector at a different event and got the same results and now I'm confused. I guess it must have something to do with the adapter but not sure what.
    Any help much appreciated.

    You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
    That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
    Refresh & sesolution are the first things to look at.
    Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
    I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

  • No audio via Mini-DisplayPort. MBP 5,5

    A 2009 MBP does not support audio via the minidisplay port.  For audio you will have to tap the audio output port and use RCA connectors to the audio inputs on the TV.

  • HDMI audio through TV "mix" issues

    Hi All,
    I've got my ATV2 connected vai HDMI to my Phillips LCD TV, it seems there is a phasing problem or something....I listen to music I am familiar with and the vocals seem mixed very low, and I know it's not right.  Most likely the issue is with the TV, but I have adjusted as many settings as I could find, and there seems to be no fix.  In fact, if I turn off the "Super Surround" audio mode, I get some really terrible sounding phase cancellation/comb filtering sounds.  Just wondering if anyone has heard anything like this.
    Thanks!

    If you connect the MacBook using a Mini DisplayPort to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo sound system if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.
    If you have the Late 2008 model 5,1 Aluminum Unibody or Late 2009 model 6,1 White Unibody with the Mini DisplayPort rather than the Mini-DVI there is an adapter that uses the Mini DisplayPort and a USB port to combine video and audio to HDMI. It's only 2 channel stereo not 5.1 Dolby Surround.

  • Audio and Mini DisplayPort on Late 2009 iMac (27")

    I have a Late 2009  27" iMac and a 42" HDTV that I would love to hook up with eachother so I can start using Plex-and-the-likes on the bigger screen.
    But I'm wondering if the Mini DisplayPort of this iMac supports audio, as I do not want my sound to come from the other side of the room when watching stuff on the TV.
    I've been reading around on the net, but I can't seem to find anything conclusive that tells me that it works (some discussions and thread claim that it should work, but some official documentation regarding the Late 2009 and Mid 2010 iMacs (http://support.apple.com/kb/ht3913) only mentions the Mid 2010 one with audio output in the Mini DisplayPort
    Not sure if it matters, but I'm running a fully up-to-date OS X Lion.
    Thanks in advance.

    According to http://support.apple.com/kb/HT4241, your late 2009 iMac's displayport should support hdmi audio output, (but I have no idea whether there might be OS-X version limitations).
    Here are two attractive alternatives to the spendy apple-referenced adapters. I can't vouch for them, but they have great user reviews, and very low-risk pricing.  (I just ordered one of each to try with my MBP and new HDTV -- but neither the adapters nor the TV have been delivered yet.)
    miniDP-to-hdmi adapter from monoprice.com @ $6.65
    miniDP-to-hdmi cable from amazon.com @ $8.67
    Another interesting thought would be to skip the miniDP entirely and go with USB-to-hdmi, with an adapter that sounds almost too good to be true.  Any comments on this technology (displaylink) would be much appreciated:
