I want to update to Vista SP1, but I'm not being offered this through Windows Update. The reason is because my sound driver is one of those listed that has known problems with Vista.
See Cause#5 here: http://support.microsoft.com/kb/946532
I have a Sigmatel High Def. Audio Codec sound card and the driver file is: stwrt.sys
Here are my specs:
Dell Dimension 5150
2 GB DDR SDRAM
Intel Pentium D Dual Core Processor
Video: ATI Radeon X1600 in a PCIe x 16 pin slot (512MB Video RAM)
Audio: Sigmatel High Def. Audio CodecAudio Driver Details:
Sigmatel Stac 92XX C-Major HD Audio, Ver. 220.127.116.1143
As you can see, my driver version does not allow me to be offered SP1 as per the MS link above.
I searched for a driver on the Dell site which was compatible for my system. I used filters for Dimension 5150, E510 and "Multi System". I found a few drivers that had a later version than 18.104.22.16811 (which is the SP1 requirement), but after installing any of them, I get no sound....none of them work.
I removed all traces of the previous Sigmatel files, rebooted my computer and installed several of these "updates", one at a time. I end up getting a red X through my speaker icon, which says: "No Audio Device Detected". Device Manager shows and exclamation point with a Code 31 error.
I also tried unplugging the speakers and plugging them back in.
I need an updated driver that will WORK.
