Did this fix work? I have exactly the same problem with a VAIO VGN-FE870E...I tried the updated sound pack B driver and I got a code 53 error saying the driver couldn't load...now it's back to code 10 the device won't start...I am ready to throw my VAIO out the window...never again will I buy a Sony...any ideas?

my hwid's are:
HDAUDIO\FUNC_01&VEN_8384&DEV_7662&SUBSYS_104D0C00&REV_1002\4&B1E7652&1&0001 for the audio device

HDAUDIO\FUNC_02&VEN_14F1&DEV_2BFA&SUBSYS_104D0200&REV_0900\4&B1E7652&1&0102 for the hd modem
