Hi! I'm having trouble with one (only one) of the alsamixer settings.  'MIC1 boost AMP gain control' shoots up to 71 every time I launch a program that uses sound, such as alsaloop or arecord. I've done 'sudo alsactl store', so I can get it back to zero by doing 'sudo alsactl restore'. Obviously that's not something I want to do all the time. I don't have any problems with any other settings. The setting in question completely ruins sound quality for my purposes, so I need it to stay at zero.

 

I'm currently running 5.35 user-built Ubuntu 16.04.3 LTS 3.4.113-sun8i. I've tried Debian Jessie as well. 

You may try edit config file by command,

 

sudo nano /var/lib/alsa/asound.state

 

        control.4 {
                iface MIXER
                name 'MIC1 boost AMP gain control'
                value 0  # !!! <- change to 0
                comment {
                        access 'read write'
                        type INTEGER
                        count 1
                        range '0 - 7'
                }
        }

 

I not sure that this method could solve your problem.

 

Thanks for the reply. I think I tried that, but the problem is not that it reverts to the saved settings, which are fine. I wouldn't have a problem then. Unfortunately I don't have this installation on hand anymore.
