Thanks, Takashi

but it did not change anything for the Intel DG45ID.
This is a Genuine Intel mother board.

The sound card is detected as "Generic 8086 Intel G45 Develk",
but I do not hear anything, even with all mixer channel at the maximum
volumes.

This is a  Fedora 10, with the latest alsa packages, and
everything seems OK, the applications work, but I do no hear anything.

With the alsa driver from the latest Fedora kernel

Linux version 2.6.27.7-134.fc10.x86_64

the card is detected as IDT 92HD73E1X5 and,

although I have to put all the mixer channels at the maximum, the sound
output works fine, even mid emulation.

During the snapshot compilation, I got dozens of this warning:

This is the output of alsa-info, with the stock driver (1.0.17):
