Thank you Kevin. It turns out that did not solve the problem. I amrunning Windows 7 64 bit so the KB888111 files are for Win XP SP1, Win XP SP2 and Win Server 2003 and Win 2000 will not run. After close examination it seesm that all of the updates were installed and Windows Update reported that no more updates were needed but I noticed that SP1 was not installed. I installed it manually and then installed the new updates that Windows Update found. Thenthe audio driver installed as expected.
Thakn you for your help.
There are some steps I want you to try:
Make sure that Windows Audio service is started.
- Click Start, type services.msc and press Enter.
- Double-click "Windows Audio" service.
- Click the Log On tab.
- Click Local System account, and then click OK.
- Right-click "Windows Audio" service, and then click Start.
- Follow the same steps for "Windows Audio Endpoint Builder" service.
After this, I recommend you accessing Device Manager and uninstall the audio driver and restart the computer.
