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