MIXERCTL.CONF(5) BSD File Formats Manual MIXERCTL.CONF(5)NAME
mixerctl.conf -- audio mixer configuration file
SYNOPSIS
mixerctl.conf
DESCRIPTION
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).
