Display Port Audio Issues ( possible permissions )

[JBE]

Hi All,

 

We have some Dell OptiPlex 7010 Running Windows 7/32 Enterprise. They're i5's running Smart Panels through Displayport to HDMI adaptors.

 

All teachers profiles are roaming and when a teacher logs on to these said machines - the Displayport Audio function disappears, forcing them to use USB Audio which has proven to be a bit unreliable with drop outs etc. When I log on the machines with Domain Admin - the option to use Displayport Audio is there and it can be used with no issues, so I am guessing we have a permissions / roaming profile issue here?

 

 

Troubleshooting I have done:

 

Logged in with our test roaming profile account, gone in to playback devices and made sure that disabled and disconnected devices are ticked.

Made my test roaming profile account local admin on the machine.

Checked device manager to see if it shows up - it does not - does as Admin.

Checked the Sound and Audio third party settings.

 

I am at a bit of a loss, but possibly think that a registry entry or permission may needed to be added / changed to get this to work?

 

Has anyone had any experience of this and if so, how did they fix?

 

Cheers
