Here is the log from Hwids:

Am I blind or is there no SC device listed???

Anyway, my money is on the missing HDA hotfix (KB888111).
Which notebook these days does not come with HD sound?

Easy solution:
Slipstream SP3 into your XPCD (you will want that anyway) and there you go.
Inlcude the DriverPacks (especially Sound) and you whould be set.

Would be surprising if this one (didn't look it up, though) wasn't using Realtek HDA...

have you use driverspacks in your installation ??

No luck with that one either ....

Unfortunately I find myself in the same situation like many other people here that downgraded from the crappy Vista that came with the laptop to XP and now can't find the driver for the SOUND CARD. I checked the manufacturer website and downloaded all the drivers from there, no luck so far. I already checked the Intel website with 0 luck as well. You guys are my last option.

Thank you,
Cristian.
