How to change the first microphone to second microhpone in "mixer_patchs.xml" ?

Hi Friends ;)

I have damaged the front microphone to talk but the second microphone is working.

I would like to change to make the system does not use a microphone first during a telephone conversation

I would like the system to use another microphone during talks.

I think that the microphone config should be placed in the file mixer_patchs.xml

The problem is that I cantdistinguish which microphone is named.

Please Help.

Phone Xperia SP but I think that this file is for all android device.

mixer_patchs.xml

<mixer>

<!-- These are the initial mixer settings -->

<!--

NOTE: For all the mixer controls added under usecases or sound devices

we should have an initial mixer setting (default value)
