Hello there!  I have a Radeon 6850 video card and I use the HDMI Audio as my sound output.  Sometimes however, it disappears on startup and I have to use the executable and reinstall it.  I don't know what causes this.  Anyone out here have an idea? Thanks!

Hi

 

The very first thing you need to do is to update your ATI driver. First go to control panel and uninstall ATI drivers completely. You can find the latest ATI driver from http://support.amd.com/us/gpudownload/Pages/index.aspx

 

 Report back if the problem still continues after updating drivers.

Alrighty - I downloaded that file. First I uninstalled the 6850, then ran the file.  The HDMI Audio didn't come back, though.  I ran my existing driver file for it and it's back now.  So - I just need to run my computer as I usually do, maybe restarting it a few more times than usual and see if the problem returns.

Thank you for your help!

Well - it happened again.  Error code: 88780078

I wish I knew what caused this.

Have you attempted to run Chkdsk?  Run it with the repair option enabled and perhaps that would fix whatever has broken in Windows...

 

To run chkdsk (just in case you don't know), right click on the main drive in My Computer->Properties->Tools->Error Checking->check both boxes and press "Start"...

CHKDSK found no errors - the disk is clean.

Frustrating.

Thank you for your time & advice. :thumbup2:

Hi

 

How HDMI shows in device manager? Is it in yellow question mark ? . If it already installed then open "sound and audio device" in control panel and set HDMI audio as the default sound output device. Usually it will be your built in analogue audio.

There's nothing amiss in Device Manager. In Sounds and Audio Devices, HDMI is the default output and the "Use only default devices" box is checked.

Hi Mr.bleepen

 

From what i understand your ATI HDMI is installed correctly but you don't get any sound output ob start up. When  you re run ATI driver setup audio works fine. Is that correct ?

 

If that is so, there are mainly two possibilities.

 

1) Outdated onboard audio driver.

    Reports from net indicates updating on board audio driver may solve issues with HDMI (Although seems unrelated)

 

2) Bug in ATI driver.

 

  There is a known bug in new ATI driver which causes problem with HDMI. Downgrading driver to version 12.1 seems to solve this problem.

Uninstall your current driver and install ATI catalyst version 12.1

Alrighty - I uninstalled version 13.1 and installed version 12.1.

So far, everything works as it should. Fingers crossed.

Thanks guys!

Oh boy... it happened again today.  Seems so random.  I can't think a single thing that might trigger this behavior.

I'm still open (and hoping) for more advice and or solutions.  Thanks guys!

I have not tried that yet.  How would that affect my sound driver being rolled back?

There may be a chance. Also it could be simply a fault of ATI driver. They are notoriously famous for making buggy drivers. You can also try uninstalling onboard audio driver. This may force the system to use HDMI audio as the default audio device.
