Audio says it's working but no sound?

Hi All,

This is the first time a simple search hasn't led me to a solution (it's now been 2 days of searching) so I thought I'd sign up and see if anyone here can help me.

I transported my computer from home to uni, set everything up again and my audio has mysteriously stopped working.

This is what I've tried so far:

• Testing speakers on another computer (they work)
• Reinstalling the latest Vista drivers for the Realtek HD audio and the AC '97 drivers
• Removing and reinstalling drivers
• Removing and reinstalling older versions of the Realtek drivers
• System restore (to when the sound was working)
• Enabling and disabling the speakers, SPDIF and HDMI
• Unplugging and replugging the speakers in the audio ports (windows detects this in the system sound options)
• Trying different combinations of speaker inputs and audio ports.
• Plugging my speakers into the audio ports on the front of my case
• Plugging headphones into any 'front speaker out' port
• Checking device manger for any conflicts (none)
• Checked event viewer but I couldn't find any audio related errors
• Disabling/Re-enabling HD Audio in the BIOS
• Disabling exclusive mode in the speakers properties

My OS is Vista x64 and my motherboard is an EVGA nForce 790i SLI FTW Mainboard. My speakers are Creative Inspire T6100 (though headphones dont work and these speakers work fine on other computers).

What really confuses me is that vista trundles happily on picking up sound in the volume bars and not reporting any conflicts.

Attached are some screenshots for further info.




















Any help would be utterly fantastic!

Thanks!

 

Have you checked in the Controls to ensure that Mute isn't turned on by accident?

 

I've checked services in msconfig and 'Windows Audio' and 'Windows Audio Endpoint Builder' are both enabled. When I also view Windows Task Manager I can see that AudioSvc (Windows Audio) and AudioEndpointBuilder (Windows Audio Endpoint Builder) are both enabled

I've checked everywhere I could imagine for a muted option but can't find one anywhere.

Thanks for the replies guys!

 

Thanks - good idea. Below are screens of DxDiag:

 

Here ya go :

 

I've just realised that the Realtek HD Audio Manager is picking up the wrong audio ports upon insertion.

The problem is as follows:

orange = isn't picked up
green = green and black
black = isn't picked up

I won't post a screen as it seems to get tied up in moderation.

Thanks!

 

I can't seem to edit my posts or am I missing something?

Anyway I planned to add this to the previous post:
