Audio settings on FreeBSD

mixer(8) is a FreeBSD base system utility for setting and displaying sound card mixer levels. It resembles the Linux’s command line utility alsamixer. Invoked with no parameters it shows the current values of the mixer devices:

$ mixer
Mixer vol      is currently set to  85:85
Mixer pcm      is currently set to  75:75
Mixer speaker  is currently set to  75:75
Mixer mic      is currently set to   0:0
Mixer mix      is currently set to   0:0
Mixer rec      is currently set to  75:75
Mixer igain    is currently set to  75:75
Mixer monitor  is currently set to  75:75
Recording source: mic

Setting specific values is easy enough:

$ mixer rec 80:80
Setting the mixer rec from 75:75 to 80:80.

Enjoy!
