|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Ensoniq AudioPCI and Creative Labs
|
|
SoundBlaster PCI series of audio cards.
|
|
All models based on the ES1370, ES1371, and ES1373 chips are supported.
|

By specifying:
|
|
.Bd -unfilled -offset indent
|
|
options EAP_USE_BOTH_DACS
|
|
.Ed
|
|
.Pp
|
|
a second audio device is attached.
|
|
You can use it simply by directing audio output to it.
|
|
This way it is possible for two different programs to use the "same"
|
|
audio device simultaneously.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
device driver appeared in
|
|
.Nx 1.4 .
|
|
.Sh CAVEATS
|
|
The joystick port hardware works by emulating a legacy
|
|
.Xr isa 4
|
|
joystick port, bypassing the
|
|
.Xr pci 4
|
|
bus method for address allocation.
|
|
This is unlikely to work on PCI busses other than the primary one.
|
|
There is also a possibility for conflicts with real ISA devices
|
|
because the PCI bus is probed before ISA.
|
|
Use with caution.
