The
/etc/mixerctl.conf file consists of
mixerctl(1) variables to set at boot time. Each line of
mixerctl.conf has the following format:
variable=value
To generate a
mixerctl.conf from the current mixer settings, execute:
mixerctl -a > /etc/mixerctl.conf
Set
mixerctl to YES in
rc.conf(5) to have the variables set at boot time. Additionally, you can have the settings saved and restored for the devices of your choice by listing them in
mixerctl_mixers in
rc.conf(5).
