.Dt SND_ES137X 4
.Os
.Sh NAME
.Nm snd_es137x
.Nd "Ensoniq AudioPCI ES137x 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_es137x"
.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_es137x_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
bridge driver allows the generic audio driver
.Xr sound 4
to attach to the Ensoniq 137x audio cards.
.Ss Runtime Configuration
The following
.Xr sysctl 8
variables are available in addition to those available to all
.Xr sound 4
devices:
.Bl -tag -width ".Va hw.snd.pcm%d.latency_timer" -offset indent
.It Va hw.snd.pcm%d.latency_timer
Controls the PCI latency timer setting.
Increasing this value will solve most popping and crackling issues
(especially on VIA motherboards).
.It Va hw.snd.pcm%d.spdif_enabled
Enables S/PDIF output on the primary playback channel.
This
.Xr sysctl 8
variable is available only if the device is known to support S/PDIF output.
.It Va dev.pcm.%d.polling
Experimental polling mode, where the driver operates by querying the device
state on each tick using
.Xr callout 9 .
Polling is disabled by default.
Do not enable it unless you are facing weird interrupt problems or if the
device cannot generate interrupts at all.
.El
.Sh HARDWARE
The
.Nm
driver supports the following sound cards:
