Hi, Takshi
We have no official plan to support this nforce 630i HDMI audio in linux
and we didn't do any test on it yet. So we can't provide the official
patch for this addition.

I think if someone interest in it and do some test, he can generate
patch and submit it.

Thanks.  So it's just a missing entry.

Wei, do you have a patch for this addition?

That'll be helpful.  Thanks.
