1.1 provos 59: .Sh DESCRIPTION
1.6 provos 60: The
1.1 provos 61: .Nm
62: command displays or sets various audio system mixing variables.
63: If a list of variables is present on the command line, then
64: .Nm
65: prints the current value of those variables for the specified device.
1.6 provos 66: If the
1.1 provos 67: .Fl a
68: flag is specified, all variables for the device are printed.
69: If the
70: .Fl w
71: flag is specified
72: .Nm
73: attempts to set the specified variables to the given values.
1.5 millert 74: .Pp
75: Values may be specified in either absolute or relative forms.
76: The relative form is indicated by a prefix of
77: .Dq +
78: or
79: .Dq -
80: to denote an increase or decrease respectively.
1.1 provos 81: .Pp
82: The
83: .Fl f
84: flag can be used to give an alternative mixer device, the default is
1.6 provos 85: .Pa /dev/mixer .
1.1 provos 86: .Pp
87: The
88: .Fl n
89: flag suppresses printing of the variable name.
90: .Pp
91: The
92: .Fl v
93: flag shows the possible values of enumeration and set valued
94: variables. Enumerated values are shown in [] and set values
95: are shown in {}.
1.6 provos 96: .Pp
97: The exact set of controls that can be manipulated depends on
98: the mixer. The general format (in both getting and setting a value)
99: is
100: .br
101: .Va "class.name" = value
102: .br
103: The
104: .Va class
105: can have values like
106: .Li inputs
107: or
108: .Li outputs
109: indicating that the control affects the input resp. output to the
110: mixer. The
111: .Va name
112: indicates what part of the mixer the control affects.
1.8 aaron 113: Continuous mixer values, e.g., volume, have numeric values
1.6 provos 114: in the range 0-255. If value can be set for each channel independently
115: the values are printed separated by commas. Discrete mixer values, e.g.,
116: the recording source, have symbolic names. Depending on the mixer it
117: may either be an enumeration or a set.
118: .Sh EXAMPLES
1.7 deraadt 119: The command
1.6 provos 120: .Dl "mixerctl -a -v"
121: can produce
122: .Bd -literal
123: inputs.mic=0,0 volume
124: inputs.mic.mute=off [ off on ]
125: inputs.cd=220,220 volume
126: inputs.cd.mute=off [ off on ]
127: inputs.dac=220,220 volume
128: inputs.dac.mute=off [ off on ]
129: record.record=220,220 volume
130: record.record.source=mic [ mic cd dac ]
131: monitor.monitor=0 volume
