Hi Sir,
I am enclosing the also-info for your reference. Thanks.
Comment 10 Jaroslav Kysela 2011-07-29 10:45:17 UTC 
The mixer connection looks ok. Please, enable the "Front Mic" in alsamixer (mute & increase volume). If it does not help, try keys 'z' and 'q' to disable left channel (inverted phase issue). Please, attach the alsa-info file in configuration with Front Mic enabled (in mixer configuration you believe it's correct).

Hmm, solution is simple.
1. Run "alsamixer", 
2. press "F6" for select sound car. 
3. Select HDA Intel.
4. Then press "F4"
5. Use your's arroes (left and right) and setup volume on all your microphones.

:)
I have a similar hardware.
Soundcard: HDA Intel
Chip Conexant CX20561 (Hermosa)

Output lspci: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

And some statistics: 

Pulseaudio: 0.9.22-5.fc15 (i686)
Alsa-firmware: 1.0.24.1-2.fc15 (noarch)

I hope I helped.

But, still is a bug.

alsa-info with Front Mic enable

Hi Jaroslav Kysela,
Could you help to check the attached alsa info? I run alsamixer, then there a front Mic in the playback option, I unmuted it. Thanks.

Hi Hufis,
There is only "capture" under the F4 option, it is unmuted. I suspected I will have Line-In,Mic-In in it. I think it would be another issue. Thanks.

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 19 Jaroslav Kysela 2015-10-19 07:01:13 UTC 
Could you retest with the latest RHEL6 kernel ?
Comment 21 Beth Uptagrafft 2016-08-16 16:30:42 UTC 
This issue is extremely old.  If there is still a customer affected on the latest version of RHEL6, please reopen and provide specifics.
