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.
