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:
1.11 aaron 74: .Bl -tag -width Ds
1.10 aaron 75: .It Fl a
76: Print all device variables and their current values.
77: .It Fl w Ar name=value
78: Attempt to set the specified variable
1.15 ! pvalchev 79: .It Fl f Ar file
! 80: Specify an alternative audio mixing device.
! 81: .It Fl n
! 82: Suppress printing of the variable name.
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 {} .
1.15 ! pvalchev 89: .Ar name
! 90: to
! 91: .Ar value .
1.10 aaron 92: .El
1.5 millert 93: .Pp
94: Values may be specified in either absolute or relative forms.
95: The relative form is indicated by a prefix of
1.10 aaron 96: .Ql +
1.5 millert 97: or
1.10 aaron 98: .Ql -
99: to denote an increase or decrease, respectively.
1.1 provos 100: .Pp
1.10 aaron 101: The exact set of controls that can be manipulated depends on
102: the mixer.
103: The general format (in both getting and setting a value) is
1.1 provos 104: .Pp
1.10 aaron 105: .Va class.name = value
1.6 provos 106: .Pp
107: The
108: .Va class
109: can have values like
110: .Li inputs
111: or
112: .Li outputs
113: indicating that the control affects the input resp. output to the
1.10 aaron 114: mixer.
115: The
1.6 provos 116: .Va name
117: indicates what part of the mixer the control affects.
1.8 aaron 118: Continuous mixer values, e.g., volume, have numeric values
1.10 aaron 119: in the range 0-255.
120: If value can be set for each channel independently
121: the values are printed separated by commas.
122: Discrete mixer values, e.g.,
123: the recording source, have symbolic names.
124: Depending on the mixer it
1.6 provos 125: may either be an enumeration or a set.
