How to install audio drivers for Acer Revo nettop?

Question

I have a Acer Revo nettop. I wiped the XP Home install that came on the machine and put XP Pro on.

Acer's support website would lead you to believe that this product does not exist. I know it has a NVIDIA ION LE chipset so I headed over to nvidia.com to download drivers. Ive downloaded and installed the Chipset drivers, Graphics Drivers, and HDMI audio drivers.

I have no sound. Under Device Manager there is an unknown Audio Device on High Definition Audio Bus. I do not have an HDMI cable to test hdmi audio. I would just like the standard audio mini-jack output to work.

Anyone know of the correct driver or a generic driver that would work?

Thanks

Solution

Here is a guide to looking up hardware based on it's device ID.

To summarize:

1. In Device Manager, right click your unknown device, and select Properties.
2. Go to the "Details" tab.
3. With "Device Instance Id" selected, you'll see a string such as the one listed below.
4. Use PCI Database to lookup what device this corresponds to.

HDAUDIO\FUNC_01&VEN_8384&DEV_7690&SUBSYS_102801C0&REV_1022\4&2DC3B72F&0&0001

• VEN_8384 indicates my Vendor ID is 8384.
• DEV_7690 indicates my Device ID is 7690.

In the example, which is my sound card (or codec so it says), searching the Device ID returns: SigmaTel 9200 HD Audio CODEC. Device Manager lists this as SigmaTel High Definition Audio CODEC, so i'd say this is pretty accurate.

From that point, its a matter of finding the drivers for your particular device on the web.
