30.Sh NAME
31.Nm snd_es137x
32.Nd "Ensoniq AudioPCI ES137x bridge device driver"
33.Sh SYNOPSIS
34.Cd "device sound"
35.Cd "device snd_es137x"
36.Sh DESCRIPTION
37The
38.Nm
39bridge driver allows the generic audio driver
40.Xr sound 4
41to attach to the Ensoniq 137x audio cards.
42.Ss Runtime Configuration
43The following
44.Xr sysctl 8
45variables are available in addition to those available to all
46.Xr sound 4
47devices:
48.Bl -tag -width ".Va hw.snd.pcm%d.latency_timer" -offset indent
49.It Va hw.snd.pcm%d.latency_timer
50Controls the PCI latency timer setting.
51Increasing this value will solve most popping and crackling issues
52(especially on VIA motherboards).
53.It Va hw.snd.pcm%d.spdif_enabled
54Enables S/PDIF output on the primary playback channel.
55This
56.Xr sysctl 8
57variable is available only if the device is known to support S/PDIF output.
