1.1 provos 63: .Sh DESCRIPTION
1.6 provos 64: The
1.1 provos 65: .Nm
66: command displays or sets various audio system mixing variables.
1.10 aaron 67: If a list of variables is present on the command line,
1.1 provos 68: .Nm
69: prints the current value of those variables for the specified device.
1.10 aaron 70: By default,
1.1 provos 71: .Nm
1.10 aaron 72: operates on the
73: .Pa /dev/mixer
74: device.
75: .Pp
76: The options are as follows:
1.19 jmc 77: .Bl -tag -width "-f file"
1.10 aaron 78: .It Fl a
79: Print all device variables and their current values.
1.15 pvalchev 80: .It Fl f Ar file
81: Specify an alternative audio mixing device.
82: .It Fl n
83: Suppress printing of the variable name.
1.17 jfb 84: .It Fl q
85: Suppress all printing when setting a variable.
1.23 deraadt 86: .It Fl t
1.25 jmc 87: Toggle.
88: Attempt to select the next possible value
89: of an enum
90: (see below).
1.10 aaron 91: .It Fl v
1.25 jmc 92: Show all possible values of variables.
93: Enum values are shown in
94: .Sq []
95: and values belonging to a set are shown in
96: .Sq {}
97: (see below).
1.20 tedu 98: .It Ar name Ns = Ns Ar value
1.19 jmc 99: Attempt to set the specified variable
1.15 pvalchev 100: .Ar name
101: to
102: .Ar value .
1.10 aaron 103: .El
1.5 millert 104: .Pp
1.10 aaron 105: The exact set of controls that can be manipulated depends on
106: the mixer.
1.25 jmc 107: The general format (in both getting and setting a value) is:
1.1 provos 108: .Pp
1.19 jmc 109: .D1 class.name=value
1.6 provos 110: .Pp
111: The
1.19 jmc 112: .Ar class
1.6 provos 113: can have values like
1.25 jmc 114: .Dq inputs
1.6 provos 115: or
1.25 jmc 116: .Dq outputs ,
1.19 jmc 117: indicating that the control affects the input or output, respectively,
118: to the mixer.
1.10 aaron 119: The
1.19 jmc 120: .Ar name
1.6 provos 121: indicates what part of the mixer the control affects.
1.25 jmc 122: Continuous mixer values, e.g. volume,
123: have numeric values in the range 0\-255.
1.19 jmc 124: If
125: .Ar value
126: can be set for each channel independently,
1.10 aaron 127: the values are printed separated by commas.
1.25 jmc 128: Discrete mixer values, e.g. the recording source,
129: have symbolic names.
130: .Pp
131: Variables may take one of three types,
132: again dependent on the mixer:
133: .Bl -enum
134: .It
135: Enums.
1.26 ! jmc 136: These may take only one out of a possible list of symbolic values
! 137: or the literal string
! 138: .Dq toggle ,
! 139: which toggles the value,
1.25 jmc 140: e.g. inputs.mic.source=mic0.
141: .It
142: Sets.
143: These can take one or more of a possible list of symbolic values;
144: multiple values are specified as a comma-separated list,
145: e.g. record.source=mic,cd.
146: Additionally,
147: .Ar value
148: may be omitted to specify the empty set,
149: e.g. record.source=.
150: .It
151: Numbers.
152: Numerical values may be specified in either absolute or relative forms.
153: The relative form is indicated by a prefix of
154: .Ql +
155: or
156: .Ql -
157: to denote an increase or decrease, respectively.
