Hi,
I am running ubuntu 7.04 on Dell Optiplex 745 with hda-intel card.
The mic does not work now. I tried latest stable alsa driver.
The chip is Analog Device AD1983.
According to the document of alsa driver, there is no more model
parameter can be set.
Can anyone give me some information about that?
Is it a defect of current driver code? Or something I missed?
thanks,
What exactly did you test for recording mic input?
I tried skype and gnome sound record.

In many cases, it's a mixer configuration problem.  So, please show
the generated file via "alsactl -f somefile store" to see the mixer
status.  Also, /proc/asound/card0/codec#* files are great help for
analyzing HD-audio problems.
$alsactl -f sound store
$ cat sound
