Hi,
(i'm not subscribed to the list, please cc me in replies)
So I'm on a Dell Vostro 1700 with latest BIOS (A07). In the default configuration, the mic is not working.
But if I append model=dell-m42 when loading snd-hda-intel, it works.
My alsa-info: http://www.alsa-project.org/db/?f=8d6f7d613b909c0eef67f93e0e86bf13476e9e54
alsa-info with option model=dell-m42 http://www.alsa-project.org/db/?f=233cee7ffea01b9f46451e64c95c4fc482ab4ee4
I don't know if dell-m42 is enough, I chose it because it was used for the Dell Vostro 1500, for which there was a pci quirk in patch_sigmatel.c, and that seemed close enough. Everything seems to work properly though.
I don't know if it's possible to add the same pci-quirk (or a similar one) in patch_sigmatel.c , or any dmi-based quirk, but I'd like to help in doing so.
I compiled a working hda-verb should some remote debugging be needed.
I forgot to add that this is also working with dell-m44. A pointer: https://wiki.ubuntu.com/InstallingUbuntuOnADellVostro1700#AUDIO : suggestion to add this option by default on ubuntu.
So, which is better, m42 or m44? This can be checked only with a real hardware...
thanks,
Takashi
