|
|
.Nd Creative SoundBlaster Live! and Audigy sound cards 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_emu10kx"
|
|
.Pp
|
|
For additional options:
|
|
.Cd "options EMU10KX_MULTICHANNEL"
|
|
.Cd "options EMU10KX_DEBUG"
|
|
.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_emu10kx_load="YES"
|
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
bridge driver allows the generic audio driver
|
|
.Xr sound 4
|
|
to attach to the Creative sound cards based on EMU10K1, CA0100, CA0101, CA0102
|
|
and CA0108 DSPs.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
sound cards have a PCM part, which is accessible through one to five
|
|
.Xr pcm 4
|
|
devices (see
|
|
.Sx MULTICHANNEL PLAYBACK
|
|
for details), and MPU401-compatible MIDI I/O controller, which is accessible
|
|
through the midi device.
|
|
Wave table synthesizer is not supported.
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the following sound cards:
|
|
.Pp
|
|
.Bl -bullet -compact
|
|
.It
|
|
Creative Sound Blaster Live!\& (EMU10K1 Chipset).
|
|
Both PCM and MIDI interfaces are available.
|
|
.It
|
|
Creative Sound Blaster Audigy (CA0100 and CA0101 Chipset).
|
|
PCM and two MIDI interfaces available.
|
|
.It
|
|
Creative Sound Blaster Audigy 2 and Creative Sound Blaster Audigy 4 (CA0102
|
|
Chipset).
|
|
PCM support is limited to 48kHz/16 bit stereo (192kHz/24 bit part
|
|
of this chipset is not supported).
|
|
.It
|
|
Creative Sound Blaster Audigy 2 Value (CA0108 Chipset).
|
|
PCM support is limited
|
|
to 48kHz/16 bit stereo (192kHz/24 bit part of this chipset is not supported).
|
|
There is no MIDI support for this card.

The
|
|
.Nm
|
|
driver does
|
|
.Em not
|
|
support the following sound cards (although they are named
|
|
similar to some supported ones):
|
|
.Pp

as

Creative Sound Blaster Audigy LS / ES, identified by
|
|
.Fx
|
|
as
|
|
.Qq Li "CA0106-DAT Audigy LS" .
|
|
.It
|
|
All other cards with -DAT chipsets.
|
|
.El
|
|
.Sh MULTICHANNEL PLAYBACK
|
|
It is possible to build this driver with multichannel playback capabilites.
|
|
If you enable the
|
|
.Dv EMU10KX_MULTICHANNEL
|
|
option in your kernel configuration (or
|
|
build it as a module) you will get up to five DSP devices, one for each sound
|
|
card output.
|
|
Only
|
|
.Dq FRONT
|
|
output can play and record sound from external
|
|
sources (like line or S/PDIF inputs).
|
|
.Sh OSS MIXER CONTROLS
|
|
These are controls available through the standard OSS programming interface.
|
|
You can use
|
|
.Xr mixer 8
|
|
to change them.
|
|
.Pp
|
|
On EMU10K1-based cards the OSS mixer directly controls the AC97 codec on card.
|
|
On newer cards the OSS mixer controls some parameters of the AC97 codec and
|
|
some DSP-based mixer controls.
|
|
.Bl -inset
|
|
.It Qq vol
|
|
mixer control is overall sound volume.
|
|
.It Qq pcm
|
|
mixer control is PCM playback volume.
|
|
It controls only front output
|
|
volume in multichannel mode and all output volume in single chennel mode.
|
|
.It Qq rec
|
|
mixer control acts very different on EMU10K1 and other cards.
|
|
On EMU10K1 cards it controls the AC97 codec recording level.
|
|
On non-EMU10K1 cards
|
|
it controls the amount of AC97 "stereo mix" entering the DSP.
|
|
AC97 recording level and AC97 recording source are fixed
|
|
on CA0100, CA0101, CA0102 and CA0108 cards.
|
|
AC97 recording level are always set to
|
|
maximum and recording source is always
|
|
.Dq Li "stereo mix" .
|
|
.El
|
|
.Pp
|
|
Other OSS mixer controls do not work.
|
|
.Sh PRIVATE DEVICE CONTROLS
|
|
You can control most of EMU10Kx operation and configuration parameters through
|
|
.Va dev.emu10kx. Ns Aq Ar X
|
|
sysctls.
|
|
These
|
|
.Xr sysctl 8
|
|
values are temporary and should not be relied
|
|
upon.

|
|
The

|
|
device driver first appeared in
|
|
.Fx 7.0 .
|
|
.Sh AUTHORS
|
|
.An -nosplit
|
|
The PCM part of the driver is based on the
|
|
.Xr snd_emu10k1 4
|
|
SB Live!\& driver by
|
|
.An "Cameron Grant" .
|
|
The MIDI interface is based on the
|
|
.Xr snd_emu10k1 4
|
|
MIDI interface code by
|
|
.An "Mathew Kanner" .
|
|
The
|
|

|
|
device driver and this manual page were written by

|
|
.Sh BUGS
|
|
8kHz/8bit/mono recording does not work.
|
|
8kHz recording was removed from the driver capabilites.
|
|
.Pp
|
|
The driver does not detect lost S/PDIF signal and produces noise when S/PDIF
|
|
is not connected and S/PDIF volume is not zero.
|
|
.Pp
|
|
The PCM driver cannot detect the presence of Live!Drive or AudigyDrive
|
|
breakout boxes
|
|
and tries to use them (and list their connectors in the mixer).
|
|
.Pp
|
|
The MIDI driver cannot detect the presence of Live!Drive or AudigyDrive
|
|
breakout boxes and tries to enable the IR receiver on them anyway.
