Microsoft Bus driver problem when installing sound on a Vaio FS-155E

[bartsimp]

Hi, I'm re-installing XP to get something cleaner than the overloaded default XP and I have the following problem:

When I install the sound driver, I have a message at around 50% of the install that i have to load the Microsoft Bus driver prior to installing sound (realtek HD audio).

Where on eart can I find this thing?

Any help will be greatly appreciated.

Thanks

That¿s interesting, two people posting on the same day with exactly the same problem.

I don¿t claim to know the solution, but this document may help you.

Hi thanks for your answer.
THis doc explains the bits and bites but my problem seems to be that I can't find the driver.

I've got a FS115Z and I'm doing the same - reinstalling the operating system to get it clear of all the applications and things I don't need. I've also got to 50% when installing the sound driver and get exactly the same error.

I've never seen this problem on any of the machines I've set up in the past and there's not much on the internet.

I'm going to be on the phone to Sony tomorrow morning, but if anyone has any ideas they would be welcome!

Ok, let's keep this thread live then. I look forward to your news

Just for your information there is a third person with the same problem. If you reply to his thread he may be able to provide further information.

I've tried sony and they tell me they only support factory install from recovery DVD's!!

I have a feeling that you need your motherboard chipset drivers.
Download Everest Home Edition.

Computer > Summary will show your chipset manufacturer and should also have a link for downloading the latest drivers (it does on mine).

Just in case either of you have missed this, have a look at this.

Thanks for your posts. I've just read the last post, although I've already fixed it.

The problem is Microsoft's UAA driver, which is not part of the Audio Driver download on the Sony site. If you look at Microsoft's Knowledge Base article 835221, it will describe what the UAA architecture is.

The link on the previous post that was kindly put on there is a Realtek Audio Driver, the same as the one you can download from the Sony site, but it includes Microsoft's fix "kb835221.exe" in directory "MSHDQFE". That installs the UAA drivers into the Windows system and then you need to reinstall the drivers for the problem PCI device in Device Manager. This will then automatically find the drivers for audio and modem.
