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.

You should mute this. Otherwise you'll hear the sound from mic as analog-loopback.

Raise this volume.

my mic works with raising mic boost volume. thanks.

Turn on this. Otherwise you cannot record.
