chanook*xyz* I have the same situation as lforbes--Dell Support shows an up
dated Sigma Tel Driver but I have no idea whether it is for my system or
not. I have vista home basic 32-bit and has a Sigma Tel High Definition
Audio CODEC driver. So am not sure if the one Dell is showing is compatible
for me. Does anyone have a clue for me?
Thank you for your help.
