Before upgrading my OS I want to be sure that the machine is in good condition. Maybe the recent sound problems--no sounds at all, not even windows sounds--are hardware related, or software related. Does this mean I should put this new topic in the XP sub-forum? If they end up being software related will the topic be moved somewhere else?
I read the help article here
Missing or lost sound in Windows. I'll review the steps I followed as in the order in this article.
I cannot see the icon for sound in the tray icon area. Cannot get it back.
No conflicts or errors were shown in Device Manager.
Under "other devices" the only item is the one listed below: "Audio device for High Definition Audio Bus", which has a yellow
?, and the message "The drivers for this device are not installed. (Code 28)".
"Sound, video and game controllers" is there. No named "sound card" is there.
Was not willing to do this:"Under Sound, Video and game controllers highlight each device and press the delete key to remove the device." but did delete the drivers. (How would windows know which devices were there? Maybe some are not standard for this machine?)
On reboot the message came up that the drivers were installed except for one: "Audio device for High Definition Audio Bus".
And now on every boot I get a "Found new Hardware" dialog to install the driver for this HDAB. But the driver is never found by the wizard.
I read elsewhere that allowing windows to install drivers is a recipe for disaster because it won't know the specific driver model for my machine. So I have to use the drivers from the manufacturer, in my case Lenovo (T61).
Speakers are fine.
