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
1.16 pvalchev 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.
1.17 jfb 83: .It Fl q
84: Suppress all printing when setting a variable.
1.10 aaron 85: .It Fl v
86: Show the possible values of enumeration and set valued variables.
87: Enumerated values are shown in
88: .Dq []
89: and set values are shown in
90: .Dq {} .
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
1.10 aaron 107: .Va class.name = value
1.6 provos 108: .Pp
109: The
110: .Va class
111: can have values like
112: .Li inputs
113: or
114: .Li outputs
115: indicating that the control affects the input resp. output to the
1.10 aaron 116: mixer.
117: The
1.6 provos 118: .Va name
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.
122: If value can be set for each channel independently
123: the values are printed separated by commas.
124: Discrete mixer values, e.g.,
125: the recording source, have symbolic names.
126: Depending on the mixer it
1.6 provos 127: may either be an enumeration or a set.
