Acer Aspire - audio driver and display problem

by corsair990 / April 19, 2008 10:40 AM PDT

Hi guys, I recently bought an Acer Aspire 5720-6661 via Newegg. It had vista premium installed but i wanted xp pro so i downgraded it and have been installing the drivers ever since.

the problem occurs with the audio driver. the sound was fine on the vista, but when i went to xp, i was unable to find the driver that worked for my laptop. i found several but none worked. when i go to dxdiag under "run" and go to sound, all the info's are blank. no name, no device id, no nothing.

same with the display tab, which brings me to my second problem. the laptop screen works... sorta. when i use my middle button on my mouse to scroll up and down a page, it is not smooth at all. it is like the screen is slowly being updated frame by frame. i wish i could show you what it is like but it is quite difficult to describe. im guess that it has to do with the driver missing also.

here are the specs:

acer aspire 5720-6661

intel core 2 duo processor t5250
nvidia geforce 8400 gs 256 mb

i think that is the most relevent spec....the graphics. i really hope you guys can find the solution for me.

note that this is xp now so im not sure if vista drivers will work anymore.

thanks in advance

I use that as an example install. You have to research which you need for your laptop. Either with google or going to Right or wrong I can't do driver hunts for members. I will assist in pointing out a direction but that's it.

i managed to find a driver for the not sure if this is it but i think it is as close as i am going to get

its name is:

i see the word vista in the end so i am kind of dubious.

when i installed it, it went through smoothly and asked to reboot. i did so but i still have a problem. is there any way to check if it is the computer having issues installing the driver?

machine unless you bought it from Acer. I had an issue with Gateway support when I gave them my serial number the records said Windows 98 but I had installed Win 2000. They told me i had to go threw Microsoft.

Again. "UAA"
by R. Proffitt Forum moderator / April 19, 2008 12:27 PM PDT

Microsoft is moving toward a bit of a universal driver framework, particularly with soundcard drivers. They describe this in KB articles KB888111 and in a predecessor article, and what it boils down to is that to install any HD audio driver in XP, you must *first* have the "baseline" driver for what they call the UAA Driver Framework. If you don't have the proper UAA driver, no HD audio drivers will install in XP. That explains the frequent "The device you are trying to install is not supported on this system" message.

I suspect the reason we are seeing conflicting reports on which version of the Sigmatel driver is appropriate is due to the fact that some owners are using different source media for their XP installations, some with and some without this KB888111 UAA framework driver.

To see if you are impacted by this problem while tring to install XP, do the following with your computer hooked up to the Internet (assuming you have XP on the network):

1. Go into Device Manager
2. Browse under "System Devices", and scroll down the list.
3. See if you have an exclamation point next to a generic "PCI Device"
4. If you do, right-click on the device and select "Update Driver"
5. Allow XP to search the network for the updated driver.
6. If you are affected, you will see a dialog with wording something like "Microsoft KB88111 UAA Driver Framework" being detected and installed.
7. If the driver for your sound device is already present, it will self-detect, install, and activate almost immediately upon installation of the UAA driver.
8. Your sound should be immediately available.

LAST HINT? Type KB888111 at google.
