18.04.2020 - ~1 Minute
The default sound volume of FreeBSD can be altered with sysctl.
Current default volume
In order to see the current default volume you need to query the value with sysctl.
root@freebsd:~ # sysctl hw.snd.vpc_0db
hw.snd.vpc_0db: 45Change default volume
If you want to increase the volume lower the number. For a lower default volume increase it. The changes will have immediately effect.
Increase default volume
root@freebsd:~ # sysctl hw.snd.vpc_0db=35
hw.snd.vpc_0db: 45 -> 35Decrease default volume
root@freebsd:~ # sysctl hw.snd.vpc_0db=55
hw.snd.vpc_0db: 35 -> 55Make changes permanent
The changes made to the default volume will not be permanent. After a reboot the default value will be restored. To keep the desired value after a reboot you need to edit /etc/sysctl.conf
# Default sound volume
hw.snd.vpc_0db="35"
