Problem with sound on windows 8

[idonava]

I upgraded to windows 8 pro, and whenever I hear songs, see movies, play videos in the web (youtube...) etc., I have kind of jumps in the sound itself .. and the pictures been more slower and jumping too.

My computer's specifications:
Gigabyte EP35-DS3
Intel core2duo e7200
Crucial M4 128GB
4GB DDR2 1066MHZ
Creative X-Fi Xtreme Audio
NVIDIA GeForce G210


When i played songs that happens, but less often, compared to the HD movies, it just puts the picture as well ... (Secretary as 7 years ago, if we want to play movies and we dont insatll a codecs, like K-Lite ...).
when the "jumping" occur, The Task Manager noticed the CPU consumption rises to nearly 70%, and an application called "system interrupts" takes the most consumption.
I tried to run the sound files (Mp3 and FLAC) in Foobar, MPCHC, POTPLAYER, MEDIA PLAYER.

So, I installed the proper drivers sound card (adapted windows 8) that connected in analog cable to my speakers, I checked the control panel sound card (Creative X-fi Xtreme Audio) is the main - and still repeated blasts ...
After a few trys to update several types of drivers, the problem is still there, so I decided to check with a different sound card ..

I set the Nvidia sound card (that connected on HDMI cabble to my TV) as main sound card, I run a movie and songs and the audio worked but the "jumping" are still there.

Finally, I tried through the optical port motherboard (Realtec) I updated the sound card drivers to the new ones and still it blasts ...

I tried to play the same HD Movies in XBMC Media center and the movie runs well without the "jumping" sound problem...

please help, and sorry about my bad english.

Get rid of the ExtremeAudio; its a re-branded Audigy 2 chipset thats NEVER gotten good driver support from Creative.
