Intel 82801G (ICH7 Family) High Definition Audio Controller microphone problem

[unchiujar]

I have an Intel integrated audio card

 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

on my laptop.

I am able to use it to play music but unable to use the microphone for input. I have tried the kernel with the drivers and the drivers from the ALSA site. Nothing works for the microphone. This seems to be a problem for a lot of people with this type of card(google says so), but nobody seems to have a definitive answer on how to fix it.

Any help would be greatly appreciated.

I have the Intel HDA Audio on my laptop as well, and I got the microphone to work once. I used the in-kernel drivers if I remember correctly. I just set it up normally with alsaconf to get it to work.

Of course, I have only done it once.

Can you tell me the kernel version ?

Sorry I am not much help here, but let me see if I can remember.

I think it was 2.6.20 or 2.6.21 vanilla sources from kernel.org. I want to say it was 2.6.20.

I have the same built in audio card. I have an hp laptop dv2125LA and am trying to get the microphones to work. I use fedora 6 and GNOME. It would be much appreciated to have some steps to configure the mic.

many thanks

All I did was configure the sound card with alsaconf, and then setup ekiga, and I was surprised when the mic worked. The built-in webcam worked for a while, but lately it just shows a blue screen while on. I guess I need to work on that soon.

I have this built-in sound card in my Thinkpad, I have the following modules loaded and have not run into any problems with it.

I'm running a custom-built kernel (based on2.6.31) as I want "aufs" which is a patch to the kernel at this point in time.
