NAME

     snd_ich — Intel ICH AC'97 and compatible bridge device driver

SYNOPSIS

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

           device sound
           device snd_ich

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

           snd_ich_load="YES"

DESCRIPTION

     The snd_ich bridge driver allows the generic audio driver sound(4) to attach to Intel ICH
     AC'97 and compatible audio devices.

     Some later chips, like ICH6/ICH7, depending on wiring can instead implement newer Intel HD
     Audio specification, which is supported by snd_hda(4) driver.
