[alsa-devel] HDMI v. ICH8 on Dell XPS M1330

[Armando Di Cianno]

I figured this was more appropriate for devel, and not user.  Sorry, if
that's wrong.

First, I'm using the 1.0.16 release tarballs.  They work better than the
in-kernel drivers, as they survive both suspend and hibernate, whereas
the kernel drivers do not.

I'm eager to see audio over HDMI working on my Dell XPS M1330.  I'm
pretty sure that this is /not supported/ at the moment -- if this isn't
the case, please stop reading, and let me know the particulars.  HDMI
seems to be supported noted, but mainly for the ATI chips.

I'm pretty sure the m1330 has a STAC9228 setup.  None of the suggested
model= module parameters succeeded in getting audio over HDMI, beyond
what is autodetected without any parameter specified.  model=5stack
seems to show a digital SPDIF device added.

If there is anyway I can help the core developers get HDMI audio
working, I would be glad to help.  I will post all the relevant
information I can think of following; please let me know if other
information would be helpful.  I will gladly turn on any excessive
debugging options needed.  I am an ALSA n00b, but I will happily do any
required work that I can do from this end.

Thanks!
