Public bug reported:
In Jaunty, digital mics on Acer laptops doesn't work.
There is a fix for that in Alsa 1.0.18a :
http://git.alsa-project.org/?p=alsa-kmirror.git;a=commit;h=2cc442715c45c88016c3c1c68e8828683d1b186a
This fix add a new model (acer-dmic) in Alsa HDA Intel driver for Realtek
ALC268 codec, enabling digital mics on Acer laptops (and maybe other laptops).
Current Realtek ALC268 implementation only works with analog mics.
The attached patch has been made against the package linux 2.6.28-8.24 : The
original fix apply cleanly, I have only fix the offsets.
Risks for applying this patch are low : The worst case is that this new model
doesn't work at all. But as you need to select this model by manually editing
/etc/modprobe.d/alsa-base, it won't create regressions in any case.
