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.
1.10 aaron 63: If a list of variables is present on the command line,
1.1 provos 64: .Nm
65: prints the current value of those variables for the specified device.
1.10 aaron 66: By default,
1.1 provos 67: .Nm
1.10 aaron 68: operates on the
69: .Pa /dev/mixer
70: device.
71: .Pp
72: The options are as follows:
1.19 jmc 73: .Bl -tag -width "-f file"
1.10 aaron 74: .It Fl a
75: Print all device variables and their current values.
1.15 pvalchev 76: .It Fl f Ar file
77: Specify an alternative audio mixing device.
78: .It Fl n
79: Suppress printing of the variable name.
1.17 jfb 80: .It Fl q
81: Suppress all printing when setting a variable.
1.10 aaron 82: .It Fl v
83: Show the possible values of enumeration and set valued variables.
84: Enumerated values are shown in
85: .Dq []
86: and set values are shown in
87: .Dq {} .
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
95: Values may be specified in either absolute or relative forms.
96: The relative form is indicated by a prefix of
1.10 aaron 97: .Ql +
1.5 millert 98: or
1.10 aaron 99: .Ql -
100: to denote an increase or decrease, respectively.
1.1 provos 101: .Pp
1.10 aaron 102: The exact set of controls that can be manipulated depends on
103: the mixer.
104: The general format (in both getting and setting a value) is
1.1 provos 105: .Pp
1.19 jmc 106: .D1 class.name=value
1.6 provos 107: .Pp
108: The
1.19 jmc 109: .Ar class
1.6 provos 110: can have values like
111: .Li inputs
112: or
113: .Li outputs
1.19 jmc 114: indicating that the control affects the input or output, respectively,
115: to the mixer.
1.10 aaron 116: The
1.19 jmc 117: .Ar name
1.6 provos 118: indicates what part of the mixer the control affects.
1.8 aaron 119: Continuous mixer values, e.g., volume, have numeric values
1.10 aaron 120: in the range 0-255.
1.19 jmc 121: If
122: .Ar value
123: can be set for each channel independently,
1.10 aaron 124: the values are printed separated by commas.
125: Discrete mixer values, e.g.,
126: the recording source, have symbolic names.
127: Depending on the mixer it
1.6 provos 128: may either be an enumeration or a set.
1.18 jmc 129: .Sh ENVIRONMENT
130: .Bl -tag -width MIXERDEVICE
131: .It Ev MIXERDEVICE
132: The audio mixer device to use.
