Dell U2410 DisplayPort Audio

Do all current Dell Monitors with a DisplayPort support audio output? In particular the the U2410.

The Reason for the question is that I own an ATI Radeon HD5850 Video Card and I am using the DisplayPort connection. I have installed the latest drivers (Catalyst 9.12) which mention "The ATI Catalyst 9.12 hotfix release adds support for DisplayPort audio for DisplayPort panels" The video card has its own HD Audio hardware. I have my 2.1 speaker system plugged into the 3.5mm audio output jack on the display.

Audio output works on the HDMI port. However the HDMI port is already in use with a video games console.

I have also raised this with my Video Card manufacturer, but need to confirm the U2410 is capable to output audio delivered to it via DisplayPort out of the 3.5mm stereo jack.

Oh my god! I got it working!! :-)

After installing those drivers and turning the monitor off and back on again (while logged in), the audio started coming out through the U2410 speakers!

Every time I restart the machine, after logging in, it won't play sound. But if I turn the monitor off (so the sound temporarily 'falls back' to playing through the laptop speakers), and then back on again, and it will start playing on the U2410 speakers as expected.

The rest of that CCC driver was causing crashes, so I updated to 10-7_mobility_vista_win7_64_dd_ccc for everything else, except left the 'ATI High Definition Audio Device' driver at v7.11.0.7704.

Really happy to have finally got this working! Many thanks for your help Rossisen!

Hi Chris M

Can you send a copy of that email too.

If it is not much trouble can you leave the answer for all to see here or point to FAQ which answers it.

Thanks

Patrick.

Engineering response - The U2410 produces audio on DisplayPort assuming the graphics card is able to produce the audio also.

If the card supports DisplayPort Audio, it needs driver for the audio component as well. Can you tell me if there is a folder called HDMI or DisplayPort from the driver package?  Or after you installed the driver, is there a device listed as ATI Audio device in Device Manager?

In Device Manager is:      ATI High Definition Audio device

In Audio Devices is:         Ati HDMI Output

But nothing listed for Ati DisplayPort Output. Will check with engineering.

Apparently AMD/ATI release new Catalyst video drivers every month and the version number is a date stamp ie Catalyst v 9.12 = Decemeber 2009

Recently a leaked beta Catalyst 10.1 driver has shown up on the web. I have noticed the HDMI Audio Driver is now named HDMI/DP Audio Driver (DisplayPort?) and the version number is 7.11.0 and my current driver version is 5.0.6 (Found in device manager)

- The beta driver package is 320MB

I would wait until the new 10.1 Catalyst drivers are released (within a week I hear)

- CrossFire X profiles per application will now be in a separate XML file that it will be possible to update independently of the driver itself
- ATI CrossFire X with PowerPlay for the Radeon 5x00s: reduced energy consumption of additional cards
-AMD Dual Graphics: Possibility of combining performances of the IGP of the RS880 with the forthcoming entry level GPUs from the Cedar and Park ranges.
- 3D Stereoscopics: Update of the D3D driver so as to allow third party firms such as IZ3D to use their 3D solution with 120 Hz screens. Support for Bit Cauldron glasses.
- Eyefinity: Bezel Management
- Better GPU acceleration in Windows 7 Video Converter
- Support for DisplayPort Audio (already in the 9.12 hotfix)
- If laptop manufacturers allow it, possibility of installing the Catalysts on a laptop in Vista and 7
- Improvement of 2D performance in Linux
- Support for Ubuntu 9.10 and OpenSUSE 11.2

I'll try updating the audio driver to 7.11.0 and let you know of my results here.
