Window 7 Realtek HD driver - Static with Media Center  

I am about give up. I have read every website and tried many idea but nothing can fix this.

Using media center I get a very loud static. I have fixed it many times but then it comes back. I have reloaded the system and used only defaults and it works for awhile but then it comes back.

I have tried both the windows drivers and Reltek Vista driver. Every other sound works great (CD, MP3, DVD and Pandora). I use this system mostly for recording off DIRECTV.

I have tried change many setting as other treads have suggested.

Any idea would be great.

Thanks for the help - I went home and media center was working again and I hadn't change anything. It will fail within a few days and I will then try what you suggested.

Pakers, you could try and do something i did this morning. My problem is that I can't get the system to stop freezing on 64bit when i open or close microphone problems so I tried uninstalling audio drivers.
Start>RIGHT CLICK My Computer> Manage>Device Manager> Sounds>right click on all the audio drivers you have installed and click uninstall them. Then restart the computer. See if Windows will reinstall drivers for you.

When I did this it installed DTU drivers which It did not install originally. Just a thought.

This might be related.
What happens in my case is if i am watching A TV feed in media center it will work fine until a scheduled recording starts up. than i will get the loud static POP CRACK ... POP ... with lines popping up in the middle of the screen at the same time.
However if i stop the feed I'm watching and start it up again the static will go away. or if i start watching a channel after the recording has already started i will not get any static. that might seem like a work around but the problem is, then the same type of static will be in the recorded feed. i have two tuners both of them are "Avertv Volar Max" USB's

In my case Media player/Media center couldn't play 720p movie files without hickups hissing and popping. Tried all drivers both from HP (HP Touchsmart TX2 laptop upgraded from Vista 2 Win7) and from individual vendors (AMD/ATI and Realtek) but no real solution, only slight improvements.

I fixed this by installing Zoomplayer 7. Zoomplayer guarantees a smooth and hickup-free playback even with 1080p movie files (I used the Avatar trailers for testing)
Unfortunately this didn't fix Media player...but hey I can watch video's again!
