I just bought a notebook Lenovo G450 and I had drivers not found problem. My OS is Windows XP SP2. In Device Manager, there are four "Audio Device on High Definition Audio Bus" device with exclamation mark. Below is the link to the screenshot of my device manager (pardon me, you have copy-paste the link manually since my post count is still below 5 so I cannot post link/image here):
There is no sound problem since I had successfully installed the sound driver from lenovo (The name is "Conexant High Definition SmartAudio 221" as you can see on the screenshot above) and the sound is working without problem. I also had installed Microsoft UAA Bus Driver before installing the sound driver.
I had tried installing realtek and nvidia high definition audio driver and all required drivers from lenovo (http://consumersupport.lenovo.com/en/DriversDownloads/drivers_list.aspx?CategoryID=370748), but still no avail. The four yellow exclamation marks is still exist.
So I need help to identify what actually are the devices that shown as "Audio Device on High Definition Audio Bus"? And where can I get the driver for that devices?
These are the device IDs:
I already searched the device ID with google, but cannot found any information about them.
Thank you in advance.
