HP 6005 Pro SFF audio through DisplayPort

[Jorabi]

My client has connected his 6005's DisplayPort to a DisplayPort to HDMI adapter, and that to a Sharp flatscreen TV. Audio is not making it to the TV.  I am trying to confirm that HP supports audio through the DisplayPort and through the HDMI adapter (adapter is HP) before looking for other solutions.  Windows 7 audio device settings look correct.  TV audio settings look correct.

Hi,

Please check the symbol of the port. Port with DP+ symbol may support audio but very very very very cracky and the successful rate could be around 5% at this stage, they have to work a lot more for this technology.

Hope this helps.

Thanks but i want to know if it is supposed to work in this model or not. It either is or isn't in the design but I can't find it on any spec sheet.

Hi,

Port with DP+ symbol may support audio. If only marked as DP then NO.

Hope this help.

Are you saying that the information is unpublished for this model, and I have to call my client and ask him to examine the back of his pc with a flashlight? That sounds ridiculous to me. If you don't personally know if this model does it, I am asking someone else to chime in.

Hi,

Yes, sometimes we have to do that way. Many information VENDORS (all of them) do not publish anywhere. Please read this:

I/O Ports SFF/MT
USB 2.0 Front - four (4) ports
Rear - six (6) ports
Serial one RS-232 compatible port standard
second port available as an option
Parallel one port available as an option
eSATA one port available as an option
PS/2 color coded support for keyboard (purple) and mouse (green)
Video VGA and DisplayPort provide integrated dual independent monitor support
DVI output available via optional DisplayPort to DVI Adapter
Audio Front - microphone & headphone
Rear - line input (supports microphone or line input), line out
NOTE:
See Audio/Visual section for information on re-taskable audio ports.
NIC Industry standard RJ-45 port accesses the integrated network interface controller

Hope this makes sense. In short, the red statement implies: audio does out from Display Port. By the way, it ONLY came with, nothing about HDMI !

HP DisplayPort to DVI-D Adapter
HP DisplayPort to VGA Adapter
HP DisplayPort Cable

This is a user2user forum - you will rarely find somebody with exactly the same configuration as you mentioned.
Nevertheless some try to help.
If you want HP help you should contact them directly:

For the problem of your client - there are 4 different graphics card listed, which one are we talking about?
Also - have you already gone through this document:

I realize this is a user forum; I thought these integrated sff PCs were popular and someone else was bound to have the problem and/or answer.

The client PCs in question are the ones with an integrated DisplayPort on the motherboard, adapter type AMD Radeon 4200, 785G chipset, motherboard 531966-001.  I could not find a datasheet anywhere from HP or AMD that clearly states whether this implementation supported audio or not.

I contacted HP support and their answer almost matched what Banhein said. "If the display port has 2 ++ symbols then the unit carries both audio and video. If it has just 1 + symbol then it carries just the display and not the audio."

Further, if there are two ++ symbols, audio is also passed through a DisplayPort-to-HDMI adapter providing the adapter supports audio passthrough (HP's adapter does, according to support).

I am going to the clients to confirm all of this is true and it works. I will only post again if it does NOT work.

I hope this post helps future searchers.  Now, how do I give Kudos to myself?

Well, the 6005 Pro has 2 + symbols, but the sound still doesn't work (Not HP's adapter, but the adapter works with sound on other systems).

[Jorabi]

I went to my client's and the 6005 Pro displayport has the ++ symbol, the hdmi adapter is from HP, and no sound is passed through. Windows does not recognize any additional audio device in the system, other than the built-in sound card. 

I am now running a separate 3.5mm audio cable from PC to TV and setting the hdmi input on the tv to get it's audio from the pc audio input.  I've already wasted too much time on this.
