.Sh NAME
.Nm snd_sbc
.Nd Creative Sound Blaster ISA 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_sbc"
.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_sbc_load="YES"
.Ed
.Pp
Non-PnP cards require the following lines in
.Xr device.hints 5 :
.Bd -literal -offset indent
hint.sbc.0.at="isa"
hint.sbc.0.port="0x220"
hint.sbc.0.irq="5"
hint.sbc.0.drq="1"
hint.sbc.0.flags="0x15"
.Ed
.Sh DESCRIPTION
The
.Nm
bridge driver allows the generic audio drivers including
.Xr sound 4
to attach to Creative Sound Blaster ISA compatible audio cards.
.Pp
The value of flags specifies the secondary DMA channel.
If the secondary
DMA channel is C, set the flags to (C | 0x10).
For a sound card without the
secondary DMA channel, the flags should be set to zero.
.Sh HARDWARE
The
.Nm
driver supports the following sound cards:
