UAA describes a class driver initiative for computer audio solutions that are supported in Microsoft Windows operating systems.
An audio device that is UAA-compliant can rely on the operating system for driver support. Therefore, hardware vendors do not have to supply a custom driver for a device. A High Definition Audio device can reside on an internal audio card, or the device can be part of an integrated motherboard chip set. In the spring of , Intel Corporation released the first hardware that includes High Definition Audio-compliant solutions.
The update that is described in this article supports the Intel High Definition Audio-compliant hardware. Apparently the sound was working and stopped and this seems to be the culprit. I would love to get it working withouth having to re-install the whole OS since getting all my applications setup is going to eat two weeks of productive time which I do not have. I have been all through that process already. I read that brief, I finally got to the relevant support section I mean one day the system was workin, next day while using it I get a BSOD and since then its all downhill and the support for this problem seems to be a finger pointing game.
If it occur in XP, you need to contact Acer to deal with it. VIsta is now a beta product. Don;t expect everything will be work find at the moment! By the way, I know it may not cost any money if you need to get the update fix from MS.
My friend get one from MS too. Have emailed them repeatedly for 2 weeks and they have not responded. I tried getting the files from MS support and it seems they want this to be paid for. I think I could install the drivers and work the problem myself. The situation has worstened since I last posted.
It Vista ran really crappy so I opted to stick with XP for the timebeing. SO FAR What is UAA? UAA is Microsoft's Universal Audio Architecture; an audio driver architecture model supported by the operating system. All of these audio components work together to provide a high-definition audio experience on your HP or Compaq PC.
If you are trying to install an audio driver update, and a UAA error opens, and your computer is using Realtek HD Audio, try downloading and installing the latest driver from Realtek's support site: www. Download and save sp to your hard drive. Save it in a location where you can easily find it later.
Double-click sp that you downloaded earlier and install the files according to the instructions. When the installation is complete there will be no notification and sound will still not work. After the computer has been restarted.
If sound is still not working, install the sound driver. Before the audio driver can be installed, the installer first needs to verify that the correct UAA files are installed and are intact. If the installer cannot detect the proper files for UAA, the installer opens the message window and exits the installation.
The installation does this to protect your PC from further problems that could occur if the UAA files were missing or the wrong files were used. These messages are most likely to occur if you have changed or upgraded the operating system for example, from Windows Vista to Windows XP. These messages can also occur if the login account does not have the proper permissions to install the software. Obtain and install a new audio driver package that matches the new operating system.
