An old distro is all currently released distros though. As far as I
know, no distro using the correct kernel will be available until
sometime next month at the earliest (ubuntu 8.10.) Otherwise, I am sure
the "trick" I used for Fedora 9 would work with all of the other distros
I haven't been table to test HDMI audio output, but I can tell you that
HDMI is listed in the aplay -L list of devices. I'll get to testing
this soon, after I can recompile and test the X11 driver.

I opted to get an IN-WIN BM639 for two reasons:
1. It was on the list of cases at intel that were "certified" for this
2. It accepts a full sized optical drive. Once the system looks more
stable, I plan to add a blu-ray drive. A standard blu-ray is < $150. A
slim blu-ray drive is MUCH more expensive.
It has a built-in 120w power supply. The case fan is a large 80mm fan,
unusual for mini-itx cases. The power supply does have a tiny 40mm fan,
but I haven't been able to hear it.
I'm quite pleased with the level of sound coming from the case... This
will be the 4th active front-end, and using stock components, it is as
quiet as one of my fully ATX desktop frontend systems where all of the
components were chosen for quietness. I think the hard drive (temporary
until I can get minimyth fully working, at which point I will switch to
either network boot or USB key, though in my testing, I really like the
USB key, it is booting very quickly) is the loudest component currently.

More testing to do, but supposedly a fix has been checked in, I just
need to get the source and recompile.
This chip is supposed to support hardware accelerated playback of all
blu-ray formats and most everything else. How long it takes to get
support in Linux is a different question. I am hopeful that something
will become available, I just don't know how far off it is. VA API
seems to have stalled, and I'm reading that people are extending XvMC to
support HD formats as a stop-gap measure until VA API can be completed.
