HDMI Audio Quit

I have a Dell i3847 desktop with Windows 7 Pro - 64bit. Some time during the night my power went off shutting down my computer. When I started it this morning there was no sound with my HDMI cable that runs to my Samsung display. Last night it worked fine. The video is still fine.

I have checked to make sure that all disconnected and disabled devices are shown. They are. I uninstalled the audio driver in Device Manager, rebooted, and Windows reinstalled the driver. No help.
I tried a new HDMI cable. No help.

For whatever reason my computer can no longer see the Samsung display. When I check for playback devices it is no longer visible.

I pushed F12 on boot up and ran the diagnostics. Nothing found.

Anybody have any suggestions?

Thanks for the reply. I don't see the video in the Device Manager. What would it be called in WIN 7?

Good morning.

I uninstalled the following devices:

1) High Definition Audio Device (It had a yellow triangle next to it.)

2) Standard VGA Graphics adapter (No yellow triangle.)

3) Universal Serial Bus Controller (It had a yellow triangle next to it.)

When I rebooted, I got the following message:

Device Drive Software not Successfully Installed

High Definition Audio Device - failed

Universal Serial Bus Controller - no driver found

Standard VGA Graphics adapter - ready for use

I also went to the Realtek web site. I think that is the brand of my HD audio device. I download a new driver from their site. It took awhile. It cycled through two reboots and I was optimistic. No luck. I still have a red X on the Audio Icon on the task bar and no sound.

Yes, I have a Dell Inspiron 3847. I used Dell's software to find my model and service tag number just to be sure.

No matter. I fixed it. I went to the Intel driver site and downloaded their latest audio and video drivers. I'm back in business.

Thanks for your support during a very frustrating time.
