Proliant ML10 DisplayPort Audio

[TotalGriffLock]

Hi,

I am using a Proliant ML10 Gen9 as a high-end workstation, one of its advertised uses. The computer has 2 DisplayPort 1.2 graphics outputs. DisplayPort should carry audio via the Intel HD Graphics (the graphics drivers should install drivers for Intel HD Audio) however this does not seem to happen on this computer. As a result Windows reports no playback/audio devices and no sound gets sent to the DisplayPort device. I have installed, uninstalled and reinstalled the latest Intel HD Graphics drivers. I know the monitor supports DisplayPort audio as I have another device using the same Intel HD Graphics drivers which can output audio through the monitor. I have verified that the connection between the computer and the monitor is good, both the Intel drivers and the monitor report that the connection is DisplayPort not DVI (so it's not a cabling issue). I believe that HP have disabled the audio functionality in their Intel HD Graphics implementation. There are no BIOS options around audio functionality to enable/re-enable.

Any suggestions?

Cheers,
John

Hi,

The audio feature is not available because this device is not a desktop or workstation.

You can use usb sound card.

Yeah that makes sense. Quite infuriating knowing that all the required parts are there to do what I want to do but HP have chosen to disable it so I have to buy more hardware.

Never mind!

I'm not sure the 'requied parts' are there. While display port may be able to carry audio, I'm not sure the sound card interface is on the systemboard..

In the case of DisplayPort the audio is processed by the GPU. It's an Intel GPU, I doubt HP have removed parts of it.
