I have a Vaio Z600 which uses the 440BX chipset, so YMMV, but what worked for me was to turn off the 'Plug and Play OS' option in the BIOS. This means the BIOS explicitly initializes non-boot devices, in this case, the AC97 codec on board (not just the AC97 controller). This tends to happen with ACPI capable laptops. ICH3 is an ACPI capable chipset. Give it a try. If you're unlucky the BIOS might not have this option still, but Sony tend to leave it in the PhoenixBIOS they use.
