I've been getting the dreaded "No Audio Output Device is Installed" message, and have no sound. I have been lead down a path to download a new Microsoft UAA Bus Driver. My problem is, how can I find the right one for my computer? There are so many out there, how will I know? I've got a HP Dv2500 series laptop and am running Vista 32 bit. This has been going on for three months, so any help is beyond appreciated. Sorry for the lack of detail, I'm a newb. Thanks folks!

A couple of things to try. Go to the MS Update site and make sure you have the latest updates for Vista.

And here is where you'll find the audio drivers that came with your machine..

Actually, I believe a Windows update was the culprit for why it is gone to begin with, so I'm going to try moving forward without them for a while. I've downloaded just about everything on that list. The problem is that there isn't a UAA Bus driver available on that list. Does that mean it doesn't apply to my computer? Or how can I find a UAA bus driver that may not be on that list?

This might point you in a good direction, at least what it is, however I don't see Vista on the list...

By the way, since you said it might have been caused by an update, have you tried and 'system restore' to back before this happened?

I tried system restore, I even went as far as to re-install windows. I figured that would HAVE to fix it. Do you think that might signify a bigger problem? Is it possible that onboard sound can become disconnected? I ran a driver detective program that said my speaker is unplugged, but I'm figuring that is because it can't even be detected without this bus driver. Thanks Ekim!

Yep, I've downloaded that one before. I've tried 5/6, but none of them have Vista listed, it's kinda strange.

You said you re-installed Windows? How? By the way that particular driver is for Hi-Def Audio, do you use it that way? Can you access the sound through a USB port? Also, that driver is also associated with a modem, so you might checked on modem drivers, eh? ;)

I re-formatted and installed windows with a disk from my cousin. Sorry, I don't know how to access sound through a USB port. I have no idea if I use Hi-Def audio or not. I just want any audio at all other than the annoying beep that lets me know I have none. I've tried headphones though, and nothing changed. I downloaded the modem driver listed as well. Nothing happened. Do you think I could find sound again if I purchased a sound card? I've heard both ways. If my onboard sound was somehow detached from my motherboard, is this the kind of error I would be getting?

You re-formatted and installed Windows with a disk from your cousin? Is this a legitimate copy for your machine?

No, this is not a legitimate copy, but the problem existed before I installed it.
