EliteBook 8460p AC3/DTS audio via display port

I have 8460p and i am trying to get multichannel audio out of the displayport. I have DP to HDMI cable which works fine for getting picture. Also i get audio but its only 2 channels. Also in the playback devices section when i check the supported formats it only shows 2 channel stereo.
Would like to connect laptop to tv and tv via optical to receiver and get AC3 or DTS when watching movies.
I have 64bit Win7 and latest drivers from hp site.
As a temporary solution i am currently using Lindy usb audio adapter with optical out which is working for AC3/DTS.
Thanks

The bug is known, and a patch has been submitted: https://bugs.freedesktop.org/show_bug.cgi?id=80151. There's been no update since friday, so I wonder what the current status is, or if it's up for review at all.
Does anyone know how we can be notified when this patch hits the kernel?

HP Elite 8300 Ultra Slim No Audio via Display Ports -Solution-

This is a solution or a work around to getting audio functionality via the Display Ports on the HP Elite 8300 Ultra Slim and I suspect but cannot confirm as I do not have "other 8xxx models". Normally in the windows sound settings it will offer no options for audio via HDMI, etc with whatever drivers you so happened to install from HP or Intel when using the Display Ports on the machine.
So this is what I did and I replicated it again to be sure.
1.Install the Latest Intel HD 2500 Drivers first from the Intel Website first of course
2.Download the HP Power Assistant Software v2.0.5.1
http://h20565.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_102595_1
and install it and suddenly in the Sound settings in the Windows Control Panel you will find it now shows audio devices that are connected via the Display Ports via HDMI , weird I know but it works for any audio device connected to the DP pots via HDMI, etc.
HP Customer Services told me categorically that it was not a function of the 8300 Ultra Slim supports due to the revision of display port it has so I am a bit annoyed that I had to search and search and actually fix it myself.

Great discovery.
I may experiment on my 8000 and 8200 Elite CMT's.
I would have to remove the video cards I added though.
FYI, so you don't have to go to third party websites, HP does have a direct link to the Power Assistant software you used.

LA2206XC - audio via Display Port input

Anyone know if the la2206xc is capble of auido in via the display port interface?
I have just hooked one up to my new Intel NUC Kit DC53427HYE but I cannot get audio to come through the speakers on the la2206xc. All three Digital Audio devices show as "not plugged in".

Hello sideshowtob. Before I can thoroughly assist you, I need to ask a few questions.
What OS are you trying to use?
What computer is the monitor connected to?
I'm also going to provide you a link which contains drivers for the monitor, which may need to be installed or updated. Please answer these questions and try the below link as soon as possible. I'm here to help!

AC3/DTS audio on non-AC3/DTS system...

Hello.
I'm running ATV OS 3.0.1 and recently I've been ripping my DVD/BR collection into iTunes. When I rip my DVD/BR discs, I include AC3/DTS audio. Right now I don't have a AC3/DTS speaker system, but since I plan to in the future, I figured it would be best to rip that way. I'm just using the analog stereo cables (right/left) from the ATV to my TV and assume there's some downconverting built into the ATV to handle this?
Anyway, the problem I'm having is that the voices when people speak are usually really hard to hear, while the rest of the sound (music, FX, etc.) is way loud. So, we end up cranking the volume when we can't hear people talking, then the next scene is some action scene and the volume is crazy loud.
Does anyone know what might be wrong/a possible solution?
Any help would be appreciated!
Thanks,
k.

Sorry, let me clarify, for the sake of these boards. These are home movies I'm ripping, not commercial. Since I assume I'm dealing with AAC stereo (since I'm getting sound and I don't have a system capable of AC-3) we can ignore DTS and maybe WC will go away.
i'm sure you will want sir winston on board, as he is very knowledgeable when it comes to TV matters
So — back to the issue, which I'll now consider a stereo issue. I'm using handbrake to rip my home movies, using one of the ATV presets. When I'm speaking in my home movies, my voice is low in the mix (it's not this way when I watch my home movie from the DVD I burned myself at home).
Any idea's why this would be?
i have similar experiences when playing movies through my TV alone (via HDMI). however, once audio goes via optical to my surround receiver, the output is just as it's supposed to be.
my guess is is you won't know until you get that speaker system. AFAIK, the TV is able to pass whatever audio it is receiving through via optical.
please correct me if i'm wrong !

Will an X220 drive a Dell UP2414Q 4K 3840 x 2160 Monitor via Display Port?

I've not been able to find any information about this on the web and there is definitely some confusion about DisplayPort versions - could some one answer the question will an X220 drive a Dell UP2414Q 4K IPS Monitor at it's native resolution of 3840 x 2160 Monitor via Display Port? Would that be at 30Hz rather than 60Hz?
Many thanks, Mark.
Solved!
Go to Solution.

The X220 will drive the Dell UP2414Q 4K resolution through Displayport. I have tested this on the Pro2840m LCD which has the same resolution. But only on 30 hz refresh rate.
The X220 with the Series 3 Workstation Dock will drive 2 of the Pro2840m through 2 separate displayport.
The X201 will also drive this 4K resolution, as long as the LCD's 4K can accept Displayport 1.1 standard (on the 1.2 standard, the LCD will stay blank).
https://www.flickr.com/photos/lead_org/14671257827/in/set-72157645860787090
the above image confirms the 4K resolution and my X220 driving that resolution @ 30 hz.
For 60 hz refresh rate on the 4K resolution with integrated Intel GPU, you need Haswell CPU with the HD5000 graphics card, anything below that will only drive the 4K resolution at 30 Hz.

Audio mini display port - hdmi

Hi, I have a Macbook6,1 (2010) and I would to know if I there is a mini display-port to hdmi cable with audio support.
Thank you.

It wasn't a glitch. It wasn't until 1 1/2 years after they developed the Mini DisplayPort that they figured out how to route audio through it. From Wikipedia: "On 13 April 2010, Apple added support for audio out using Mini DisplayPort in their MacBook Pro product line." http://en.wikipedia.org/wiki/Mini_DisplayPort
There is an adapter that can combine video and audio to HDMI.

Connecting to projector via display port

I have been using the display port on W700 via HDMI cable to connect to my projector OK and then next day can not get either to talk to each other. What might be wrong? Have tried connecting both in alternate ways with cable - switching one and then other etc to no avail. I did go to Presentation Director after using both and ticked "Capture Display settings" but unticking etc makes no difference and finally I uninstalled PD and reinstalled.

Hi StormTiger,
If you are having issues with the VGA out on your MacBook Pro, you may want to try the troubleshooting steps in the following article to see if you can isolate the issue. In particular, if possible you may want to test it with a different Mini-DisplayPort to VGA adapter to see if the issue is with the adapter or the computer.

Optical audio and display port

my question is about the display port and optical audio. This both devices has the same quality? if not, why the MACs doesn't have the optical audio? tks

both are digital it's 0's and 1's quality dont end up with 1/2's and -1's so all digital audio would be of equal quality if in the same bit range and sample rate

FIX for Dell U3011 displaying YPbPr instead of RGB via display port

I kind of hacked my way around and got my Dell U3011 to properly display RGB instead of YPbPr (or YCbCr) over a mini display port to display port cable for my MacBook Pro Retina 15"! WOOHOO! no need for that stupid $150 dual link dvi to mini displayport adapter anymore, which was incredibly flakey and sometimes the monitor turned on, and sometimes it didn't etc... lots of problems.
Download the file from:
http://www.8mmdesign.com/u3011-rgb-ypbpr-fix/DisplayVendorID-10ac.zip
unzip into:
/System/Library/Displays/Overrides
It will create a new directory called:
/System/Library/Displays/Overrides/DisplayVendorID-10ac
Then reboot the system, and it should work. Go to system preferences, displays, color, and set the display profile to Color LCD.
This will *ONLY* work for the Dell u3011 and it is completely UNTESTED. Use at your OWN RISK. But you should have proper RGB colors after doing this.
Good luck!

This post helped me: http://ireckon.net/2013/03/force-rgb-mode-in-mac-os-x-to-fix-the-picture-quality -of-an-external-monitor
I have an Onkyo AV Receiver TX-NR414, I'm using the HDMI passthru (connecting Mac to AVR, then AVR to TV) and my Macs where giving bad colors.
Connecting the Mac directly to the TV was ok.
So the problem was the need to force the Mac to output RGB, the above linked blog post has a link to a Ruby script that will create a profile with RGB output. Follow the instructions and it will get it right.

Can a Macbook send audio via DVI port?

I want to hook up a Macbook to an HDTV by using a mini-DVI to DVI adapter, connected to a cable that has a DVI connection on one end and an HDMI cable on the other.
Does anyone know if the min-DVI port supports audio?
The more expensive cable supports audio, but I don't want to shell out the extra money if the Macbook can't support it.

DVI does not carry an audio signal. It takes HDMI to do that. You'll need to use a separate audio cable.

Macbook receiving AM radio via display port connector'

A few weeks ago, I discovered that when my Mini Displayport to VGA connector was plugged in, I heard a buzz through my speakers. It didnt bother me that much, so I just dealt with it. However, today I was plugging my external speakers in, and when the connector was about half way in.. I started to hear audio that I knew wasnt on my computer. Turns out it was commentary on a college basketball game. I started to listen some more, and discovered that it was 1530am. Seeing as I use just a standard set of 5.1 computer speakers... I found this to be extremely odd, so I figured id share this with everyone. Any ideas why this may happen?

Problems like that can be tricky to track down and eliminate but this type of device often provides a solution without ever finding out for sure the root of the problem:
http://www.radioshack.com/product/index.jsp?productId=2062214
Depending on what type of connections are on the speakers you own, you may need to purchase one or more simple cable converters that go from the RCA-type plug interface of the linked device to a normal, 3.5 mm stereo mini-point connection.
Another thing that might work would be a simple choke appled to the audio cable between the Mac and the speakers:

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

T410s display port no longer works after lenovo / win7 upgrade

Arrggh... I have a Dell u2711h monitor that i connected to my t410s via display port. It worked fine until i did a lenovo driver updateand windows 7 update. Now, it just goes into powersaving mode with the display port. I backed out the windows7 updates, went back to a windows restore point from when i knew the dp worked, uinstalled / reinstalled the lenovo drivers for nvidia nvs 3100m optimus, audio, etc.
The HDMI cable works, the monitor works with display port off of another PC, but no longer on my t410s. Anybody have any ideas? I spent a lot of money getting a big monitor with a high resolution trhough dp, but now i can't use it. Very fustrating.
Any ideas?

Hi dft410s,
Please try in BIOS to isolate hardware/software issue. If problem remains, please contact local lenovo for machine inspection

External 4k monitor says no signal from display port

HELP...
I have a late 2009 27" iMac running 10.10.2 Yosemite, i bought an ASUS PB287Q 4k monitor to extend my desktop. I have connected it by MDP to DP and the Mac recognises the ASUS, shows it as a display and tells me how it is connected but the display keeps saying "display port no signal"
If i run bootcamp and boot into windows 7 Ultimate on the same iMac the screen works perfectly giving me a 4k screen at 2160p to work on alongside the iMac with the same Display port cable.
If i use OS X with a MDP to HDMI connector the screen works as it should but with a max resolution of 2560 x 1440 only.
I have unplugged everything and re-connected, tried turning on the ASUS at different times, reset P Ram but still it will not work?
Obviously every part is working but just not from OS X
The ASUS is also set to display port 1.1
Please can anyone help????

Hi Brett,
Thanks for your response, I'm on an iMac not Macbook but checked your link, All my software is up to date and there is no updates for the Asus and nothing for the mini dislayport to display port cable.
Everything works as it should via display port if i run bootcamp into windows 7 just not from OS X so would seem like a Mac Graphics driver issue perhaps??
I was hoping it would be a glitch that would correct itself by unplugging the cables or resetting the P Ram but no such luck so i am open to any other sugestions.
The iMac can see the Asus at all times just doesn't seem to send the signal to the Asus?
I would be happy to supply any logs that may shed some light on this issue.
Kind Regards
Mark
