My ramblings on the stuff that holds it all together
Installed Windows Vista SP1 and Have No Sound?
There are probably a number of reasons for this, but I’ve come across a number of people recently that have installed Vista Service Pack 1 from the Microsoft Web site (note: not via Windows Update) following articles on the web about its availability (like mine) and have since had problems with sound or other devices not working.
If you read this KB article you’ll note that cause 5 says if you have some particular devices you will not be offered SP1 by Windows Update as there are not yet SP1 compatible drivers.
I don’t know for certain as I don’t have any of these devices on my laptop by I would think even if you downloaded it manually the SP1 installer would warn of this; so maybe those people just chose to ignore it – none of them could remember 🙂
To be fair to Microsoft I think this is a good idea, previously there would have been no check mechanism for known incompatible drivers, this is definitely a step in the right direction to protect people from themselves 🙂
Pasted from the KB article… some of the problematic devices are listed below;
To help ensure a positive update experience, Windows Update will temporarily not offer Windows Vista SP1 to systems that have the following device drivers. In some cases, these device drivers are problematic on Windows Vista-based computers when you update to Windows Vista SP1. By installing updated device drivers, you will resolve the issue and enable Windows Update to offer Windows Vista SP1.
