1.1 provos 60: .Sh DESCRIPTION
1.6 provos 61: The
1.1 provos 62: .Nm
63: command displays or sets various audio system mixing variables.
1.10 aaron 64: If a list of variables is present on the command line,
1.1 provos 65: .Nm
66: prints the current value of those variables for the specified device.
1.10 aaron 67: By default,
1.1 provos 68: .Nm
1.10 aaron 69: operates on the
70: .Pa /dev/mixer
71: device.
72: .Pp
73: The options are as follows:
1.19 ! jmc 74: .Bl -tag -width "-f file"
1.10 aaron 75: .It Fl a
76: Print all device variables and their current values.
1.15 pvalchev 77: .It Fl f Ar file
78: Specify an alternative audio mixing device.
79: .It Fl n
80: Suppress printing of the variable name.
1.17 jfb 81: .It Fl q
82: Suppress all printing when setting a variable.
1.10 aaron 83: .It Fl v
84: Show the possible values of enumeration and set valued variables.
85: Enumerated values are shown in
86: .Dq []
87: and set values are shown in
88: .Dq {} .
1.19 ! jmc 89: .It Fl w Ar name Ns = Ns Ar value
! 90: Attempt to set the specified variable
1.15 pvalchev 91: .Ar name
92: to
93: .Ar value .
1.10 aaron 94: .El
1.5 millert 95: .Pp
96: Values may be specified in either absolute or relative forms.
97: The relative form is indicated by a prefix of
1.10 aaron 98: .Ql +
1.5 millert 99: or
1.10 aaron 100: .Ql -
101: to denote an increase or decrease, respectively.
1.1 provos 102: .Pp
1.10 aaron 103: The exact set of controls that can be manipulated depends on
104: the mixer.
105: The general format (in both getting and setting a value) is
1.1 provos 106: .Pp
1.19 ! jmc 107: .D1 class.name=value
1.6 provos 108: .Pp
109: The
1.19 ! jmc 110: .Ar class
1.6 provos 111: can have values like
112: .Li inputs
113: or
114: .Li outputs
1.19 ! jmc 115: indicating that the control affects the input or output, respectively,
! 116: to the mixer.
1.10 aaron 117: The
1.19 ! jmc 118: .Ar name
1.6 provos 119: indicates what part of the mixer the control affects.
1.8 aaron 120: Continuous mixer values, e.g., volume, have numeric values
1.10 aaron 121: in the range 0-255.
1.19 ! jmc 122: If
! 123: .Ar value
! 124: can be set for each channel independently,
1.10 aaron 125: the values are printed separated by commas.
126: Discrete mixer values, e.g.,
127: the recording source, have symbolic names.
128: Depending on the mixer it
1.6 provos 129: may either be an enumeration or a set.
