120Gb 5400rpm HD
Windows XP SP2 

i tried with the driver R171789, but doesnt work yet

thanks for your time

That's the driver I'm using with XP, and I haven't had any problems at all.

Have you updated Windows through Windows update? 

What do you mean by "doesn't work yet"? Does it give you an error message?

hi, with R171789, the installer go well without any error message, but the audio never doesnt work.

I tried other audio drivers too and every installer show me a error with the device compatibility

thanks for your time

Did you install the chipset driver 1st? 

Try extracting the files from R171789 to some directory by running it. Then go into the device manager and double click on the Sigmatel audio, click the driver tab, click update driver and point it to the location where you extracted the files from.

Sigmatel audio doesn't appear in the device manager, and i install first the chipset driver.

hi, finally, i solved my audio problem XD, thanks for your time

the solution was install first http://www.yournewdriver.com/SIGMATEL_STAC_92XX_C_Major_HD_Audio_Dell_8580.htm

then this does not work fine, but it appear in the device manager, then i choose i update the driver with R171789 manually.

i hope that this information could help somebody
