When I run the Hardware Detection provided by OSX68Tools, my audio device is reported as below:

00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02)

When I try to install hardware from there, it asks me to choose the Codec, but none of those work.

My computer is a Toshiba A205 and everything works, but the sound.

What would be the steps to get it fixed? Any hints?

Thanks a lot and Merry Christmas to you all! :-)

Try search in google: Toshiba A205 alc
You'll get hints for ALC268.

or try with Hackintoshsearch:

hint:
pcwiz ALC268

Just for future reference, if you have a Toshiba A205 with ALC 268 you want to install the drivers from this thread:

It works out of the box :-)
