58: .Sh DESCRIPTION
59: The
60: .Nm
61: command displays or sets various audio system driver variables.
62: If a list of variables is present on the command line, then
63: .Nm
64: prints the current value of those variables for the specified device.
65: If the
66: .Fl a
67: flag is specified, all variables for the device are printed.
68: If the
69: .Fl w
70: flag is specified
71: .Nm
72: attempts to set the specified variables to the given values.
73: .Pp
74: The
75: .Fl f
76: flag can be used to give an alternative audio control device, the default is
77: .Pa /dev/audioctl .
78: .Pp
79: The
80: .Fl n
81: flag suppresses printing of the variable name.
82: .Sh EXAMPLES
83: To set the playing sampling rate to 11025 you can enter
84: .Dl audioctl -w play.sample_rate=11025
85: Note that many of the variables that can be inspected and changed
86: with
87: .Nm
88: are reset when the device is opened. This can be circumvented
89: like this
90: .Dl (cat file.au; audioctl -f /dev/stdout -a) > /dev/audio
91: or
92: .Dl (audioctl -f /dev/stdout -w blocksize=1024; cat file.au) > /dev/audio
