While the drivers we downloaded from Windows Update (WU) for the Toshiba Tecra running Windows 7 Ultimate x64 (previous blog post) worked quite well, we had an HP laptop running Windows Vista Home Premium that did not.
We allowed the drivers for the HP’s Conexant audio device to download and install and sure enough, on the next reboot there was no longer any sound being produced by the speakers.
It took running the HP Update Assistant to verify all of the drivers on the laptop and subsequently the download and install of the HP specific drivers for that laptop to bring the sound back.
We disable driver checking and downloading in WSUS by default due to past experiences like this.
We also tend to avoid drivers offered by WU, but this time we took the risk and lost. So, we will again avoid drivers offered up by WU unless there is a very specific need for them.
