The audio device can be inspected and changed by audioctl,
and the mixer device by mixerctl.  The command syntax was
inspired by sysctl.

.Sh NAME
.Nm audioctl
.Nd control audio device
.Sh SYNOPSIS
.Nm audioctl
.Op Fl f Ar file
.Op Fl n
.Fl a
.Nm audioctl
.Op Fl f Ar file
.Op Fl n
.Ar name ...
.Nm audioctl
.Op Fl f Ar file
.Op Fl n
.Fl w
.Ar name=value ...
.Sh DESCRIPTION
The
.Nm audioctl
command displays or sets various audio system driver variables.
If a list of variables is present on the command line, then
.Nm audioctl
prints the current value of those variables for the specified device.
If the
.Fl a
flag is specified, all variables for the device are printed.
If the
.Fl w
flag is specified
.Nm audioctl
attempts to set the specified variables to the given values.
.Pp
The
.Fl f
flag can be used to give an alternative sound device, the default is
.Pa /dev/sound.
.Pp
The
.Fl n
flag suppresses printing of the variable name.
.Sh EXAMPLES
To set the playing sampling rate to 11025 you can enter
.Dl audioctl -w play.sample_rate=11025
Note that many of the variables that can be inspected and changed
with
.Nm audioctl
are reset when the device is opened. This can be circumvented
like this
.Dl (cat file.au; audioctl -f /dev/stdout -a) > /dev/audio
or
.Dl (audioctl -f /dev/stdout -w blocksize=1024; cat file.au) > /dev/audio
.Sh FILES
.Bl -tag -width /dev/sound

.Sh NAME
.Nm mixerctl
.Nd control audio mixing
.Sh SYNOPSIS
.Nm mixerctl
.Op Fl f Ar file
.Op Fl n
.Op Fl v
.Fl a
.Nm mixerctl
.Op Fl f Ar file
.Op Fl n
.Op Fl v
.Ar name ...
.Nm mixerctl
.Op Fl f Ar file
.Op Fl n
.Fl w
.Ar name=value ...
.Sh DESCRIPTION
The
.Nm mixerctl
command displays or sets various audio system mixing variables.
If a list of variables is present on the command line, then
.Nm mixerctl
prints the current value of those variables for the specified device.
If the
.Fl a
flag is specified, all variables for the device are printed.
If the
.Fl w
flag is specified
.Nm mixerctl
attempts to set the specified variables to the given values.
.Pp
The
.Fl f
flag can be used to give an alternative mixer device, the default is
.Pa /dev/mixer.
.Pp
The
.Fl n
flag suppresses printing of the variable name.
.Pp
The
.Fl v
flag shows the possible values of enumeration and set valued
variables. Enumerated values are shown in [] and set values
are shown in {}.
.Sh FILES
.Bl -tag -width /dev/mixer
.It Pa /dev/mixer
