I tried installing the HD Audio Bus driver hotfix (KB888111) in case that was the problem, but it reported that my service pack version was newer and so this fix wasn't needed.Īfter much head scratching and fiddling around, I came across the answer thanks to Googling. Device Manager showed a (?) PCI Device under Unknown Devices, but no driver I tried would work with it. I came across this problem today, and thought I'd share my solution with you all, in case someone encounters the same problem.īasically, I figured it was time for a fresh install of Windows XP, and so to save some time, I decided to slipstream in the RC Beta of Service Pack 3, as well as all the drivers I was likely to need.Īfter Windows finished installing, all my devices were installed, but there was no sound. ↳ ThinkPad X20/X30/X40 Series incl.Fix for no HD Audio in Windows XP SP3 Fix for no HD Audio in Windows XP SP3.↳ ThinkPad SL and L Series until L420/L520.↳ Forum Notices, Questions and Suggestions.FORUM RULES, HOW-TOs and FREQUENTLY ASKED QUESTIONS.There seems to be lots on the web about sound and XP on the T61 but nothing seems to work for me.

Not sure if these three problems are connected to the sound. The only thing wrong in Device Manager is that I have three yellow ? called 'Base System Device' which I cannot get rid of.ĭetails from Device Manager of these three yellow ? are: As this doesn't work in SP3, I uninstalled SP3, installed UAA and redid the Soundmax driver.Īll installed OK, Soundmax says its installed OK, all volumes are on max BUT no sound at all, no beeps, clicks, XP start up tune, nothing.

I did some searching and found out about UAA Bus Driver (KB888111). I have tried installing the driver from the lenovo site, tried using Windows Update and no joy. I installed XP Pro SP2 and all is well (so far) except for the audio. I acquired it without hard drive and op sys.

Sorry if this has been covered before but I couldn't find this problem in the other topics.
