Even with the correct drivers as part of the driver pack BSOD occurs on ASUS P4S800-MX board (Portcls.sys)

Could the problems with drivers for Realtek, Soundmax (blue screen portcls.sys) et al be associated with KB888111 as it seems Microsoft has two versions of this Universal Audio Architecture (UAA) High Definition Audio class driver ?

KB888111 and KB835221

Gigabyte GA-965P-DS4 (Realtek High Definition audio) motherboard requires Microsoft UAA (Universal Audio Architecture) Bus driver package - KB835221 to be loaded before installing the audio function drivers.

Microsoft state that KB888111 only applies to HD Audio known to it prior to August 1, 2004

Have same problem as others with crash portcls.sys if onboard sound is enabled during install.
