HDMI Audio Output via Mini Display Port to Sharp Aquos TV cuts out every 10 seconds

I haven't had an issue til I recently did a software update to my Mac Pro.
I have two mini-display ports on the back of my machine but always have been able to listen to audio from the HDMI connection without an issue. Anyone else having this issue? I checked and reset all the setting on my Television and get prompted that a icompatible PCMI audio signal is being recieved.
PLEASE HELP!
Thanks!

I have seen one report that this is an acknowledged bug in OS10.6.8, the only cure for now is reverting OS:

Audio output through mini display port

2009 model macbook air 2,1. Is there an update or video card that will allow audio output using Moshi HDMI adapter?

http://support.apple.com/kb/HT4241
Only the most recent late 2010 MacBook Airs support audio over Mini Display Port.
For an older machine, you'll need something like this: http://www.amazon.com/Mini-DisplayPort-HDMI-Adapter-Audio/dp/B0033SM2BQ/ref=sr_1 _14?ie=UTF8&qid=1306806721&sr=8-14 or this: http://www.amazon.com/Displayport-Toslink-Female-Converting-Adapter/dp/B003BS2PF G/ref=pd_sim_sbs_e_5

Connect MacBook Pro 3,1 to hdmi tv via mini-display port

How do I connect my MacBook Pro 3,1 (2007) to an hdmi port on a LCD TV using the mini-display
port on my Mac? I am running Snow Leopard 10.6.8.
I have connected a mini-display to hdmi connector into an HDMI port on the TV. I've watched lots of youtube videos
on how to do this (apparently with newer Macs), but when I go to 'system preferences/displays', I have no options like 'extended TV'
or 'mirroring' and I have no resolution choices with a 'p' behind it. I've tried 'command-F1' as someone
suggested to make it 'mirror' and nothing happens.

Adding second display via mini display port

How do I add audio and video using mini display port and USB audio with HDMI connection at Home Theater Receiver from 2009 Mac-mini? DVI and optical audio outputs on Mac-mini used for primary display.

Assuming your receiver has a USB audio input, you would use an Apple Mini DisplayPort to DVI Adapter and then a DVI to HDMI cable for the video and a USB cable for the audio. You would have to go into System Preferences/Sound and under the Output tab you would have to make a selection to direct which port to send audio out of.
As an alternative to the Apple adapter, there are also third-party Mini DisplayPort to HDMI cables that avoid any need for an adapter at all.

Samsung LA32B530 Not Recognised via Mini Display Port

Hi,
Tried connecting a Samsung LA32B530 LCD Screen to my MBP. The Screen is not recognised by the system. The screen is connected via the Mini Display Port to DVI adapter and from there via a DVI to HDMI cable. Screen on flickers blue when I plug the screen in but no signal recognised by screen and the screen is not recognised in the control panel.
The MBP is connected to the screen via the HDMI1 port which is said by Samsung to be used with a DVI to HDMI cables.
Any suggestions?

Try a PRAM and SMC Reset
http://support.apple.com/kb/ht1379 for PRAM
http://support.apple.com/kb/ht3964 for SMC
If you have selected and switched to the correct HDMI ports with your TV Controller
Then try another lead.

KN9 Platinum - is audio output via both SPDIF ports possible??

I am looking at this board because it has both an optical and coaxial SPDIF output - can you tell me whether these can be plugged into and used simultaneously for HD Audio output. ie I want to be able to output a single digital audio stream from an application like PowerDVD via both connections.
Note this is not about multi streams from different applications - just a single stream via both SPDIF ports.
For an HTPC setup I want to be able to take the optical SPDIF output to a surround sound receiver and the coaxial SPDIF output into an HDMI enabled graphics card which includes audio input so I can then take both video/audio to another monitor.
Thanks for your help.
Ben

Yes, audio will do this video won't.

Firefox, youtube and fullscreen on 2nd screen via mini display port

I can make it full screen but soon as i click back here into main screen it goes to normal size
any ideas how to fix this?

Update.
Still having the problem.
I changed the mini displayport to displayport cable:
http://ca.startech.com/Cables/Audio-Video/DisplayPort/6-ft-Mini-DisplayPort-to- DisplayPort-Adapter-Cable-Male-to-Male~MDP2DPMM6
to this cable and am still having the same issue:
http://outlet.lenovo.com/us/en/itemdetails/0B47091/460/8FA0422CA6EA48B0BDED71D28 7F73673
I have heard that the issue may have something to do with the number of pins contained in the cable:Try another DisplayPort cable (One that is VESA compliant). Non-compliant DisplayPort cables may have snyc issues and may also have the # 20 pin pwr cable active. The # 20 pin is not suppose to be active and it may cause damage to your hardware.
The new Lenovo cable does not indicate if it is VESA compliant.
The main issue here is that after the Macbook Pro screen flashes blue upon waking, the screen brightness keys do not function. Only after removing the mini dispalayport cables do the brightness keys (F1&F2) function again.
Would really appreciate it if someone knows how to solve this issue?
Kind regards

Hdmi to mac via minis display

i tried conncting my mac to tv with hdmi and minidisplay cable which works for windows laptop bt only mountain lion screen is visible with my mac. Do u have any suggestions

You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to use the MacBook’s keyboard and trackpad to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.

2010 MBP Audio Channel Count (Mini Display)

Hi All,
I have a MDP to HDMI adaptor that I am using successfully into a HDTV, sound is going across.
I am just wondering how many channels can go through by this method, is it just stereo, 5.1, 7.1 or what?
I know I can use the TOSLINK to get surround out but it would be nice to only use one cable =)
Cheers!

You need to get this adapter.

Wi-Fi Sharing doesn't work together with mini Display port

Hello everyone!
I can tell you fantstic problem. Sorry for my English - i'm from Russia!
The problem:
1. Share Wi-Fi via bonjour to other devices such as iPad, iPhone, windows computers, etc. I'm using Mac os X Snow Leopard! Everything is fine!
2. Just only I plugging hdmi/dvi adapter - INTERNET STOPS TO WORK!!!
It looks like fantastic. If just I plugging-off remote monitor! Internet works fine! If only turn on! - It doesn't work!
Can You only believe???
When you plug remote monitor or plasma TV via mini display port - Wi-Fi sharing is not working!!!
I try to solwe this problem about 1 year - and found this forum. Nobody on internet ask this question!!!
How can I solw this problem????
My assumptions that minidisplay port and bonjour for wi-fi sharing using the same port and mini dispay have more priority!!!
But it strange - why nobody in internet ask this question!

Yes, I actually checked that it was 7.1.2 Not sure when they released it, but I had been trying to get this to work all last night.
But I did try something new...I had set restrictions for my son in Settings. If I turn "off" all restrictions, the app will load properly and bring me to Netflix sign in.
Do you know what Restiction settings would prevent Netflix from loading? I naturally want to lock down the iPad so that my son can not surf explicit websites or install, delete, and in-app purchase. I did add Netflix to approved list though.
Thanks.

Mini display port to DVI problems

Hello community,
I have a question regarding the connection from an iMac via the mini display port to a DVI input at a TFT monitor. I have an older TFT monitor and now I connected the iMac with this monitor via mini display port -> DVI adapter -> DVI cable -> monitor.
It is quite a simple connection, but actually when I force Mac OSX to detect external monitors it does not react at all. Mac OSX behaves as if there is no connection to an external monitor.
I already told this to my reseller and they told me that the adapter is not working correctly and they gave me another one. With that one I have exactly the same problem and now I'm quite sure, that it is not a problem of the adapter, but somehow my iMac does not find the external monitor.
Is there probably an underlying problem I do not understand yet?
By the way, my very old Macbook White has no problems detecting the monitor. If I use the older video output it works fine, but the new output at my iMac 21,5 inch does not work with my monitor.
My question is, why does it not work and what kind of monitor do I need, that it can be connected with my iMac (via DVI)?

Is the adapter plugged in all the way in the Mini DisplayPort? It takes more force than you might expect.

Female Mini Display Port Adapter - Connect Monitor to Non Mini Display Port

Anyone know of a Female Mini Display Port Adapter, so I can connect the 24 LED Cinema Display to a computer that has DVI connector? Or hook the monitor up to a KVM, so I can use the monitor with multiple computers?
I know Apple doesn't make these, but does a third party?
Monoline appears to be coming out with adapters to hook a mini display port computer to DVI and HDMI, but not a mini display port monitor to DVI or HDMI.

'Mini Display port' is just a smaller version of display port, which is a slightly different version of HMDI.
No. You may be thinking of Mini DVI. Mini DisplayPort is a smaller verion of DisplayPort, which is different from DVI and HDMI.
<http://www.displayport.org/white-papers/whitepapers/DPTech_OverviewEnglish.pdf>
HDMI, display port, mini display port AND DVI are all capable of being 'converted' from one to another.
It is easy to make a Mini DisplayPort (card) to DVI (display) adapter because a DisplayPort card can be set to generate DVI signals. (Dual-link DVI is a bit more complicated since the adapter must sepatate the clock and data.). A DVI card cannot generate DisplayPort signals, so an adapter for a DisplayPort display with a DVI card would be a lot more complicated.
The ONLY thing that you would LOSE in a DVI to display port conversion is an audio signal.
HDMI is DVI video plus digital audio. DisplayPort does not use DVI video.
The point is they are all interchangeable, signal wise.
No. A DisplayPort card can generate DVI signals when a DuisplayPort to DVI adapter is detected, but a DVI cards cannot generate DiusolayPort signals.
But why should Apple make a cheap DVI to female display port when they can make more money on overpriced graphics card upgrades?
They can't make a cheap adapter, but they could have added a DVI port to the display.

I am trying to connect my mac book pro to the tv via a mini display port and a hdmi cable, the only picture that is on the tv screen is the background picture on my computer, any suggestions?

I am trying to connect my mac book pro to the tv via a mini displayport to a hdmi cable, the only picture on the tv screen is the background picture of my mbp, does anyone know what I need to connect to my samsung tv ?

Hi there. I also bought an iWires mini Display port to HDMI cable and have an LG LED/LCD TV. I plugged it in to my MB Pro and followed the very small writing that came in the package and got both audio and video going. You need to change the audio settings from within System Preferences on your Mac to select your TV as the audio output.
My concern is the data latency - do you experience a delay between moving your mouse on the MBPro and the TV displaying the movement? It is only a fraction of a second, but certainly enough to be annoying, especially in a cable as expensive as the iWire.
