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
! 87: Attempt to select the next possible enumeration value.
1.10 aaron 88: .It Fl v
89: Show the possible values of enumeration and set valued variables.
90: Enumerated values are shown in
91: .Dq []
92: and set values are shown in
93: .Dq {} .
1.20 tedu 94: .It Ar name Ns = Ns Ar value
1.19 jmc 95: Attempt to set the specified variable
1.15 pvalchev 96: .Ar name
97: to
98: .Ar value .
1.10 aaron 99: .El
1.5 millert 100: .Pp
101: Values may be specified in either absolute or relative forms.
102: The relative form is indicated by a prefix of
1.10 aaron 103: .Ql +
1.5 millert 104: or
1.10 aaron 105: .Ql -
106: to denote an increase or decrease, respectively.
1.1 provos 107: .Pp
1.10 aaron 108: The exact set of controls that can be manipulated depends on
109: the mixer.
110: The general format (in both getting and setting a value) is
1.1 provos 111: .Pp
1.19 jmc 112: .D1 class.name=value
1.6 provos 113: .Pp
114: The
1.19 jmc 115: .Ar class
1.6 provos 116: can have values like
117: .Li inputs
118: or
119: .Li outputs
1.19 jmc 120: indicating that the control affects the input or output, respectively,
121: to the mixer.
1.10 aaron 122: The
1.19 jmc 123: .Ar name
1.6 provos 124: indicates what part of the mixer the control affects.
1.8 aaron 125: Continuous mixer values, e.g., volume, have numeric values
1.10 aaron 126: in the range 0-255.
1.19 jmc 127: If
128: .Ar value
129: can be set for each channel independently,
1.10 aaron 130: the values are printed separated by commas.
131: Discrete mixer values, e.g.,
132: the recording source, have symbolic names.
133: Depending on the mixer it
1.6 provos 134: may either be an enumeration or a set.
