netchild 6020e1d27b MFC nearly everything of the soundsystem except recent commits and
most of the sysctl's (those which would introduce a new interface).
The spdif_enabled sysctl is still there (or more correctly: added
to another driver).

A rough overview what's there now:
 - new driver for ATI chips (snd_atiixp)
 - support for some Intel HDA chips in AC97 mode (no real HDA
   support!), this doesn't work with every mainboard and is
   subject to the wiring on the mainboard (no servicable parts
   inside)
 - MPSAFE and fixes for snd_als4000(4), snd_es137x(4),
   snd_via82c686(4), snd_via8233(4) and snd_ich(4)
 - 24bit and 32bit sound format support
 - feeder infrastructure (format, rate) has been reworked, new
   feeder (volume) has been introduced
 - lots of LOR and panic issues fixed
 - and a lot of small or not so small fixes I may have forgotten...

As noted in UPDATING: you may want to recompile mplayer (after booting
into the new world) to get all new features.

.Dt SND_VIA8233 4
.Os
.Sh NAME
.Nm snd_via8233
.Nd "VIA Technologies VT8233 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_via8233"
.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_via8233_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
bridge driver allows the generic audio driver,
.Xr sound 4 ,
to attach to the VIA VT8233 audio devices.
These audio chipsets are integrated in the southbridge on many VIA based
motherboards.
.Sh HARDWARE
The
.Nm
driver supports the following audio chipsets:
.Pp
.Bl -bullet -compact
.It
VIA VT8233
.It
VIA VT8233A
.It
VIA VT8233C
.It
VIA VT8235
.It
VIA VT8237
.El
.Sh SEE ALSO
.Xr sound 4
.Sh HISTORY
The
.Nm
device driver first appeared in
.Fx 4.7 .
.Sh AUTHORS
This manual page was written by
.An Joel Dahl Aq joel@FreeBSD.org .
.Sh BUGS
The
.Nm
driver
does not support S/PDIF.
There is partial support in the code, so implementing it should be fairly
easy if the right hardware is available.
