Sigmatel Audio drivers won't install  

Have a tablet PC that I just installed Seven onto. Even though it's an old box, Windows update found nearly all of the drivers. The one it didn't find is for the AC97 Sigmatel audio.

So, I grabbed the drivers I used for Vista (they're actually XP drivers) and tried to install them. Did this again and again, using different compatibility modes every time. Got no indications of failure, but never worked, either.

Tried removing the device and having Windows Update search for a driver. No luck.

Tried installing driver from selecting from list. Only Sigmatel driver in the list is for HD -- which I don't have.

Even tried the MS WDM driver -- and it refused to install it.

I read in another thread that there are supposedly generic AC97 drivers --but I can't figure out how to install them.

The relevant driver files from Vista are STAC97.sys and staco.dll -- which tells me this is a STACS AC97 audio chip. But I just can't figure out how to get a driver installed.

Can someone please help?

Thanks in advance

Looks like I lucked out and stumbled upon the solution. After trying over a half dozen different drivers, I went to the Fujitsu site, downloaded the old XP driver, set it up in VXP SP2 compatibility mode, and it worked!

Never could get the XP driver to work on Vista; had to use a Vista driver for another model machine.

Another plus for Seven!!

Sorry to bother you, but which notebook on their site has the drivers you found?

It's been a while since he posted this I contacted him thru his veiw public profile and left a message that someone else needed his help on this, Hopefully he'll check back soon with a reply. Fabe

My tablet PC is a Fujitsu T4020. The XP drivers for Sigma-tel audio installed in XP compatibility mode and work fine.

The working version is v5.10.4469.0, dated 4/15/2005.

Good Luck.

On other forums, when I get a PM, I get a popup when I login telling me that.

When I logged in today, I got no such popup here. Should I have?

Thank you, it did install... BUT, when I restart, and check the hardware profile there is no longer anything in the sound card section..... just under system devices and all it is, is the controler.

Is your tablet a T4020? Did you install the drivers in XP compatibility mode? I did that and they work fine for me.
