1.1 provos 52: .Sh DESCRIPTION
1.6 provos 53: The
1.1 provos 54: .Nm
55: command displays or sets various audio system mixing variables.
1.10 aaron 56: If a list of variables is present on the command line,
1.1 provos 57: .Nm
58: prints the current value of those variables for the specified device.
1.32 jmc 59: Variables can also be set at system startup using the configuration file
60: .Xr mixerctl.conf 5 .
1.10 aaron 61: .Pp
62: The options are as follows:
1.19 jmc 63: .Bl -tag -width "-f file"
1.10 aaron 64: .It Fl a
65: Print all device variables and their current values.
1.30 sobrado 66: This is the default, if no parameters are given to
67: .Nm .
1.15 pvalchev 68: .It Fl f Ar file
69: Specify an alternative audio mixing device.
1.32 jmc 70: The default is
1.36 ! ratchov 71: .Pa /dev/audioctl0 .
1.15 pvalchev 72: .It Fl n
73: Suppress printing of the variable name.
1.17 jfb 74: .It Fl q
75: Suppress all printing when setting a variable.
1.23 deraadt 76: .It Fl t
1.25 jmc 77: Toggle.
78: Attempt to select the next possible value
79: of an enum
80: (see below).
1.10 aaron 81: .It Fl v
1.25 jmc 82: Show all possible values of variables.
83: Enum values are shown in
84: .Sq []
85: and values belonging to a set are shown in
86: .Sq {}
87: (see below).
1.20 tedu 88: .It Ar name Ns = Ns Ar value
1.19 jmc 89: Attempt to set the specified variable
1.15 pvalchev 90: .Ar name
91: to
92: .Ar value .
1.10 aaron 93: .El
1.5 millert 94: .Pp
1.10 aaron 95: The exact set of controls that can be manipulated depends on
96: the mixer.
1.25 jmc 97: The general format (in both getting and setting a value) is:
1.1 provos 98: .Pp
1.19 jmc 99: .D1 class.name=value
1.6 provos 100: .Pp
101: The
1.19 jmc 102: .Ar class
1.6 provos 103: can have values like
1.25 jmc 104: .Dq inputs
1.6 provos 105: or
1.25 jmc 106: .Dq outputs ,
1.19 jmc 107: indicating that the control affects the input or output, respectively,
108: to the mixer.
1.10 aaron 109: The
1.19 jmc 110: .Ar name
1.6 provos 111: indicates what part of the mixer the control affects.
1.25 jmc 112: Continuous mixer values, e.g. volume,
113: have numeric values in the range 0\-255.
1.19 jmc 114: If
115: .Ar value
116: can be set for each channel independently,
1.10 aaron 117: the values are printed separated by commas.
1.25 jmc 118: Discrete mixer values, e.g. the recording source,
119: have symbolic names.
120: .Pp
121: Variables may take one of three types,
122: again dependent on the mixer:
123: .Bl -enum
124: .It
125: Enums.
1.26 jmc 126: These may take only one out of a possible list of symbolic values
127: or the literal string
128: .Dq toggle ,
129: which toggles the value,
1.25 jmc 130: e.g. inputs.mic.source=mic0.
131: .It
132: Sets.
133: These can take one or more of a possible list of symbolic values;
134: multiple values are specified as a comma-separated list,
135: e.g. record.source=mic,cd.
136: Additionally,
137: .Ar value
138: may be omitted to specify the empty set,
139: e.g. record.source=.
140: .It
141: Numbers.
142: Numerical values may be specified in either absolute or relative forms.
143: The relative form is indicated by a prefix of
144: .Ql +
145: or
146: .Ql -
147: to denote an increase or decrease, respectively.
