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. Tested by: a lot of people Requested by: ariff Submitted by: ariff

.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"
|
|

|
|
.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:

|
|
.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.
