NAME

     snd_ai2s - Apple I2S audio device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device sound
           device snd_ai2s

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           snd_ai2s_load="YES"

DESCRIPTION

     The snd_ai2s driver provides support for the Apple I2S audio controllers
     found predominantly in G4 and G5 machines, along with the snapper and
     tumbler codecs. Some machines (e.g. the Mac Mini) do not have
     configurable codecs and so lack hardware volume control.

     o   Apple Tumbler Audio
     o   Apple Snapper Audio

SEE ALSO
