Rxgain value set back to zero after system reboot

Using 1.4.5

Any idea why my rxgain setting in zapata.conf is set back to 0.0 when I reboot the box?

After every reboot I have to set it back to 3.0.

Is there a script that regenerates the zapata.conf file?

Thanks

If using Trixbox, then yes it resets it. A regular Asterisk install will not reset it on a reboot.
