    Sony VOG 110G with 15 gig HD and ext HD. Having problems with SigmaTel sound card. The Windows 7-64 bit is an upgrade from WXP OEM. It appears Win 7 does not support (backwards compatible) older sound cards. My question: Is there a way to turn off High Definition Audio in Win 7 and go back to say a 32 bit or 16 bit sound allowing me to use the original sound card. SigmaTel only offers an update to their driver but no support for Win 7 or vica versa concerning Hig Def Audio. Anyone...?! Thanks! -WR

    Sure, simply uninstall the win 7 high def audio and then install your sound-card driver from the manufacturer site...

    Thanks...I will try this week. I should have mentioned that after installing Win 7 I went to Device Mngr and looked at the driver..."Code 28 Driver not installed". So it is my understanding that I just have to use the OEM Win XP from Sony and just install the original driver for the sound card SigmaTel. I think this is what I am suppose to do and will try and get back to you and this thread cause I Googled it and there is quite a few persons out there with same problem on Win 7 upgrade. Thanks.... -WR

    You were right! Got the driver from Sony (WDM) and installed it. It should have worked the first time but not logged in as Admin. I am also embarassed to say I ahve spent 4 days--32 hours--banging my head in on PCI Input Controller driver only to find out it was Creative SB Live Gameport driver included on Sound driver. You noticed on Bio that I said "Novice"!! Thanks again...best wishes! -WR
