Loud clicking sound when trying to play a DVD

[rjmc]

HP Pavilion Ultimate d4995t desktop PC with Realteck High Definition Audio.  Vista Premium O/S.  I play my sound via my HDMI cable to the speakers in my monitor. When I attempt to play a DVD in the DVD drive, I get a loud clicking noise with no sound from the DVD.   This only happens to DVD's.  CDs play sound without a problem.  If I copy the same DVD files to the hard drive, I can play it from the hard drive and sound works.  If I plug in speakers to the audio-out and disable the HDMI output, I can play the DVD in the DVD drive and the sound plays through those speakers without the noise.  I have ran Microsoft sound tool without success.  Updated all the sound drivers.  I reloaded Vista, that corrected the problem.  But as time went on the problem came back.  I suspect the problem was caused by an Microsoft update. Anyone have any suggestions?

Hi, 

Yes, it happens after installing Service Pack for Vista through Windows Update. 

Click Start->'Control Panel -> Sound -> Playback -> Select Realtek HDMI Output, click Properties. Click Advanced Tab above, 

Unclick 'Allow applications to take exclusive control of this device', click Apply/Ok. 

Check if the issue is resolved, if not, select HDMI Output on Sound Window, click Properties, click Enhancements tab, check the option 'Disable all sound effects', click Apply/Ok.
