The "auto-loading" stuff doesn't seem to be working for me on my
PowerMac11,2, with a fresh git clone as of right now. What is the base
module that should load all the others? After a "make install", I still
had to modprobe almost everything by hand (`find ./snd-aoa -name \*.ko`
in the source directory to get a list).
When the driver finally did completely load, I saw this in dmesg:
snd-aoa-codec-tas: found keywest-i2c-bus, checking if tas chip is on it

For the record, there are two "layout-id" properties in my device tree,
as discussed in this patch:
http://patchwork.ozlabs.org/linuxppc/patch?id=4867
Ultimately, snd_aoa_codec_onyx seems to be the happy module. Only the
headphone jack was enabled; I had to use GNOME's "Volume Control" panel
applet to enable speakers or line out (both of which work).
However, volume control doesn't work at all, for both line-out and
headphone jacks. Should it?
Also, it would be helpful if the git tree were better publicized
somewhere (e.g. http://johannes.sipsolutions.net/). I had to dig through a LOT of mails to find the source.
mkdir snd-aoa
cd snd-aoa/
git clone http://johannes.sipsolutions.net/snd-aoa.git/
cd snd-aoa/
make
-Hollis
P.S. Thanks for working on this Johannes!
