I've been testing this driver for a while now and I think I've worked
out most of the bugs.
If any one's interested they can find the source code here:
A patch that adds the code plus edits the KConfig Makefiles here:
To compile it as a module you'll probably need this little patch to the
In order for this driver to work you'll of course need the ALSA drivers
as well so it will only work on kernel 2.6+, unless you add them to
pre-2.6. I also recommend updating the ALSA drivers that come with the
kernel from 1.0.4 to the latest, all of my testing was performed using
ALSA drivers 1.0.5a, but it will probably run fine on 1.0.4.
In order to use most of the ALSA applications out there you will also
need an alsa.conf somewhere. You'll need to "export
ALSA_CONFIG_PATH=/....../alsa.conf" sometime too so all your apps know
where to find your alsa.conf file, like during boot (in .profile for
example). Here's the alsa.conf file I've been using.

I've been working on an ALSA driver for the Au1000 processor AC'97 port.
Specifically for the DBAu1000 Merlot eval card. It seems to be working
in OSS emulation mode, I'm having a few problems setting up my system to
work in ALSA native mode, and it contains only a minimum of features.
i.e. it's still a work in progress, but I thought there may be someone
else out there interested in it.
I've posted a patch that should add a mips sub-directory in the sound
directory of the 2.6.6 kernel and add an au1000 sound option to the
kernel configuration menu here:
Alternately you can find just the source code here:
Great -- let me know when the driver is ready to be checked in :)
