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.
