+.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

+.Nm
+driver supports the following sound cards:
