Needs verification.

Still not working on CM/Gingerbread.

hmmm, yust installed the voice search and it was one time possible to speak into micro. After this the device seems to be busy (yellow input that is waiting for audio).
What is status to this ticket? Is it possible to help here and to get infos about the sound module?

This worked for me ...

you need to edit asound.conf with this changes and reboot

pcm.AndroidCapture? {

type hooks
slave.pcm {

type hw
card 0
device 0

}
hooks.0 {

type ctl_elems
hook_args [

{name 'ALC Capture Function' value 3}
{name 'Mic Function Capture Switch' value 1}

]

}

}

pcm.AndroidCapture?_Microphone {

type hooks
slave.pcm {

type hw
card 0
device 0

}
hooks.0 {

type ctl_elems
hook_args [

{name 'ALC Capture Function' value 3}
{name 'Mic Function Capture Switch' value 1}

]

}

}

pcm.AndroidCapture?_Microphone_normal {

type hooks
slave.pcm {

type hw
card 0
device 0

}
hooks.0 {

type ctl_elems
hook_args [

{name 'ALC Capture Function' value 3}
{name 'Mic Function Capture Switch' value 1}

]

}

}

or

you can execute this commands in debug mode in android console /dev/ttyACM0 after each reboot

alsa_amixer -c 0 sset "ALC Capture Function" Stereo
alsa_amixer -c 0 sset "Mic Function" On

Thanks aurosus,

I will test this and if OK it will be included in the next build.

Replying to divx118:

Partially got it working. First time when the device is booted and alsa opens the device (microphone) it is the correct one. Second time however it opens the wrong one and you will get the following in logcat  http://pastebin.com/LwaWxeh0

Following error keep eating your resources until you reboot.

W/AudioRecord( 2046): obtainBuffer timed out (is the CPU pegged?) user=00000600, server=00000600

Tested with the default voice dialer.
