.Sh NAME
|
|
.Nm snd_ich
|
|
.Nd "Intel ICH AC'97 and compatible bridge device driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device sound"
|
|
.Cd "device snd_ich"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time, place the
|
|
following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
snd_ich_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
bridge driver allows the generic audio driver
|
|
.Xr sound 4
|
|
to attach to Intel ICH AC'97 and compatible audio devices.
|
|
.Pp
|
|
Some later chips, like ICH6/ICH7, depending on wiring can instead implement
|
|
newer Intel HD Audio specification, which is supported by
|
|
.Xr snd_hda 4
|
|
driver.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the following audio devices:
