I would now go to the hardware manufacturers web site and redownload them and install them. It is possible that your download was slightly corrupted. Alternatively go into Device Manager and delete the item completely then reboot and let Windows find the driver.
What are you using to play the videos. It might be worth reinstalling it
I installed the driver by this program called - Easy Driverspack 5.2
I click the Start tab -> Extrac and install drivers(I) [Recommend]
I went to hardware manufacturers website and redownload the audio driver as you told me, and it still stutter while i watching videos or listening to music.And I also uninstall the audio driver and restart the windows, then let the windows automatically install the audio driver for me.The result is still the same.
I use both The KMPlayer and VLC Player, and the result is still the same.
Please help me, there must be the way to fix this.
Thanks in advance. :)
