Hi. I have an Intel D975XBX2 motherboard and I have installed FreeBSD 7 on my computer. This motherboard comes with the Sigmatel 9274D codec and the sound was not working at first. I loaded the snd_hda module with
and the sound worked! I then added
to my /boot/loader.conf file so that this module is loaded at boot time.
This sound codec is not listed as supported in the snd_hda man pages and when I load the module I get
pcm0: <HDA Codec: Sigmatel (Unknown)>
when I run dmesg, so it doesn't look like it is totally recognized. However, at least the sound output works. I am posting this for the sake of anyone who has the same problem.
