.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
|
