Hi ali
One more thing.. I'm glad i also just looked at your dxdiag file. As i also saw this in the report under System Devices
Code:
Name: ATI SMBus
Device ID: PCI\VEN_1002&DEV_4372&SUBSYS_0C81105B&REV_82\3&61AAA01&0&A0
Driver: n/a
So you still may be missing a needed driver (unless we find it's included and gets installed as part of the audio driver download link i provided in my last post)
fyi... Your motherboard has an ATI chipset. And "ATI SMBus" is a low speed controller that allows for a communication "bridge" between some of the chips on that board
After you install the audio driver
1) Let us know if your audio works
2) Also if you run a new dxdiag, does the ATI SMBus entry still list the Driver as n/a???
3) If that's the case, you might also download the XP download file i found HERE
If problems persist, post back AND also post an updated version of your dxdiag report. might have more clues
/* EDIT */
Also, probably good to be cautious and create a System Restore point before installing the ATI SMBus driver download
