i tried n9tweak but.... it only raise predriv, not the mic.

i raise the mic using alsa mixer



TX1 can choose digimic0 or analog
TX1 Digi (is for volume)

TX2 can choose digimic0 or analog
TX2 Digi (is for volume)


the TX1 is for speak,? the TX2 is for noise cacelation and camera sound recording?

apparently when a call is established the sound settings are turned on and fluctuate.
I would like to know how to modify the input values ​​from the calling program, not the alsamixer.

also if you change the settings from alsamixer when I hang up the call these back to their initial value (I think)
