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.

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

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:

or this:

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

USB Hub in Dell U3011 not working over Mini-DisplayPort(Thunderbolt) when it did with previous MBP

My previous MBP, a few years ago - the first generation with Thunderbolt - was able to generate a USB connection over Mini-DisplayPort with my Dell U3011. My late 2013 MBP is able to send display and audio, but seems unable to detect the USB hub in the monitor. I am on 10.9.4. Any thoughts or suggestions?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

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.

No audio via Mini-DisplayPort. MBP 5,5

Hello,
I have the MBP 5,5 and I am trying to connect it to my TV via the Mini-DisplayPort HDMI adpater.
I am getting video but not audio any idea?
Any help is appreciated.
Thanks,

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.
Ciao.

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:
USB-to-hdmi adapter from monoprice.com @ $43.12

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.

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.

USB over Mini Displayport in Thunderbolt port?

Hey all,
I've got a MacBook Pro Retina 13" Late 2013, I've got it connected to an Acer B296CL 29" monitor. I'm connecting it with a Mini DisplayPort to DisplayPort cable, with the Mini DisplayPort end plugged into one of the Thunderbolt ports on the Macbook, and the DisplayPort into the monitor.
As far as I was aware, DisplayPort could carry USB?
I was hoping to utilise the USB ports on the monitor, so I could use the monitor as a dock, connecting to it via the MDP to DP cable, without having to also plug in any kind of USB dock to the MacBook to connect USB devices.
Is what I'm trying to do possible?
Thanks, Jack.

Displayport itself can't carry USB except in the dual-link cable configuration if the graphics chip on board the Mac supports it.
You are probably better off getting a thunderbolt hub if you don't have enough ports. A hub like this may be helpful:

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.

13" MacBook Pro (Early 2011) doesn't detect display over mini DisplayPort HDMI adapter in Mountain Lion 10.8.2

Hi to all.
I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.
If anyone has solved such ploblem, please let me know.

In reply to my own post have to say appologies to Apple whose Thunderbold port I used to blame.
Shame on me)
So, what was my problem?
Guess what?
Manhattan DisplayPort to HDMI Adapter !
The point is it's actually do only what it said to do, converts DP to HDMI.
But I for some reason thought it can be used vice versa, to be HDMI to DP converter))
I was wrong.
I bought new one HDMI to DVI adapter and now I HAVE external display!
Thunderbolt works like a charm.
So I'm very satisfied now.

Options for VGA to S video/ composite video over Mini displayport

I have a mid 2009 13" macbook pro that i want to connect to a standard def tv with s video and composite inputs. I already own the mini displaport to VGA adapter. I have found two adapters on amazon that convert VGA to s/composite video. one is $4 and is just a cable. The other is a $40 box with vga input and video output. my question is, do i need to shell out for the expensive one or will the cheap cable do just fine? i have heard NTSC out a lot while poking around. does my computer have that?
Adapter #1 (cheap one) http://tinyurl.com/yc6topv
Adapter #2 (expensive one) http://tinyurl.com/yd6qnvs
Any help would be greatly appreciated.
Thanks!

Hello, I am first time forums user and a new mac owner.
What I am having trouble with is a very similar thing but I have a brand new macbook pro 17 so I am pretty sure my connector is slightly different. I found this...
http://store.apple.com/us/product/M9319G/A
This seems to be a connector which comes out of the mini-dvi port and has a connector for rca/svideo. I have a mini-dvi to vga that I bought with the mac and then I have an old vga to rca/s-video connector cable like the cheap option the original poster gave.
My mac responds as it should but the tv signal is totally screwed up. I also tried hooking it to a projector using rca and that said no signal. The mini-dvi port to vga works but I am not 100% on the vgs to rca connector I haven't used it in so long. It is going to be a pain for me to test it though.
Should this work? DO I need to mess around with refresh rates?
Thanks

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)

Connect MacBook Pro with Mini DisplayPort to TV?

I have a 15" MacBook Pro with the Mini DisplayPort outlet. I used to have a PowerBook which I was able to connect to my TV via the video adapter. No such adapter is included with my MacBook. How can I connect it to my TV to view videos, movies, tv shows, etcetera?

You only need a cable from MBP to Display, i.e. Mini DisplayPort Male to HDMI Male Cable
Link: http://www.cablematters.com/pc-30-30-gold-plated-mini-displayport-male-to-hdmi-m ale-6-feet-cable.aspx
It's only $9.95.
But you know, until now Mini DisplayPort can not output audio but only video. As far as I know Cable Matters Inc. has solution for audio output.If you want high audio quality Mini Displayport Male and Toslink Audio/USB Male to HDMI Female Adapter is good for you since it supports 5.1 Channel audio.
Link: http://www.cablematters.com/pc-56-26-mini-displayport-male-and-toslink-audiousb- male-to-hdmi-female-adapter.aspx
The price is $47.95, a little expensive. You will need another HDMI to HDMI cable from this adapter to the TV/Screen.
If you don't require high quality audio this is an alternative Mini DisplayPort Male and USB Male Audio to HDMI Female Adapter.
Link: http://www.cablematters.com/pc-24-32-mini-displayport-male-and-usb-male-audio-to -hdmi-female-adapter.aspx
The price is cheaper for $37.49. You will also need an HDMI to HDMI cable from this adapter to your TV/Screen.

Mirror the same audio over two different outputs

Hi,
I've got a MacMini (late 2009, running Lion) set up in my living room and connected to my HDTV. The audio goes to my amp via the built in digitial audio out and toslink cable.
I recently added a second TV in my bedroom and connected it via the mini display port and a HDMI cable. Unfortunately this version of Mini does not support audio over mini display port so i bought a separate USB audio card. This is connected via a Jack plug to my audio in on my bedoom TV (no amp here, non-digital stereo audio).
I would like to be able to have video and audio in both rooms at the same time. Video is working very well, but the audio does'nt come along. I can only set the audio to one output. I tried to make an Aggregate device, but still the audio sounds over one output. I tried this with both stereo audio (music) and with 5.1 audio.
Offcourse I googled and found that an aggregate device is used for creating multiple channels for audio, not for mirroring.
What i'm looking for, is some kind of setting or software(i hope) that can mirror my audio to both outputs, and if nessecary, format into the right source (5.1 for the toslink and 2.0 for the USB device). Ofcourse, everything needs to be in sync with video and eachother.
Is there such a thing?
Thanks for any help offered.

1) Don't know why this is happening. It may have something to do with
I downloaded from iCloud the same library I was working with
I'm not clear what procedure you're using here. Using a cloud for storage might change some file tags. Generally users I think keep the library on the same drive as the media, keeping the library backups on the system. There is no real benefit in keeping the media in a separate location. Often users will keep the library in the same folder as the media. It makes backing up using tools like Carbon Copy Cloner very efficient.
1a) This can be difficult to find as there sometimes is no obvious indicator. It might be a missing element in a compound clip, a missing or altered layer in a graphics file, a missing font, a missing effect. These will show up inside the item involved, but may not be apparent in the browser. A missing transition for instance will not be seen until you skim over the project or try to export it.
2) The 43 MB is a small amount of optimized media. This never prevents relinking. The library is always looking for original media, or proxy media if you're in proxy playback. It never looks for optimized media. If it has it, it uses it, if it doesn't, it uses the original media. If you are using original/optimized playback, you must have the original files. The optimized files are not enough.
