'From where alsa getting their default states?
I am trying to get knowledge on alsa. When I saw it, it is automatically storing the previous states of the mixer controls and restoring them in the reboots. So I commented this process from the files /etc/init/alsa-restore.conf /etc/init/alsa-store.conf . After that I make one control to True and rebooted my system. After rebooting I checked the value of the control which is false now.
From where alsa get that control value as false after reboot.
There is no file /var/lib/alsa/asound.state because I removed it.
Solution 1:[1]
The initial state of mixer controls is determined either by the driver or by the device itself.
Furthermore, when asound.state does not yet exist, many distributions will call alsactl init.
If you want a mixer control to have a specific value, you must set this value somehow.
If you don't want to rely on asound.state, you could run your own script that sets the control with amixer.

To edit alsamixer settings in linux
use command:
$ alsamixer
just type alsamixer to open alsamixer in terminal
