DESCRIPTION

19       The  mixerctl  command is used to control various features of the audio
20       mixer and to get information  about  the  audio  mixer  and  the  audio
21       device.
22

OPTIONS

24       The  following  options  are  supported.  If  no options are specified,
25       option -i is assumed:
26
27       -a            The command applies to all audio devices.
28
29
30       -c control    Indicates a control to access. If -w is not supplied, the
31                     information  about  the  control,  including  its current
32                     value, are printed.
33
34
35       -C            Prints a dump of the entire set of controls for the audio
36                     device  including  current and possible settings for each
37                     control.
38
39
40       -d dev        The dev argument specifies  an  alternate  audio  control
41                     device for the command to use.
42
43
44       -i            Prints  the  audio device type information for the device
45                     and other related details.
46
47
48       -s file       Saves control values to file.
49
50
51       -r file       Restores control values previously saved to file.
52
53
54       -w value      Changes the setting of the named  control  to  the  given
55                     value. The format of the value depends on the type of the
56                     control.
57
58                     For boolean controls, the value can  be  either  'on'  or
59                     'off'.  For  enumerations,  value  is one of the possible
60                     strings given in the control information. For stereo val‐
61                     ues,  value  takes  the form of either a pair of integers
62                     (0-100, inclusive) separated by a colon or a single inte‐
63                     ger  by  itself. If two integers are supplied, they refer
64                     to the left and right values,  respectively.  If  only  a
65                     single  value  is  supplied,  then  value applies to both
66                     channels.
67
68                     For example, 50:100 means 50% volume on the left  channel
69                     and  full volume on the right. A value of 0 means silence
70                     on both channels. For monophonic (mono) values, the  num‐
71                     ber is a single integer from 0-100, inclusive.
72
73
74       -v            Verbose  mode.  Prints  additional  information about the
75                     device and operation being performed. This option implies
76                     the -i option.

ENVIRONMENT VARIABLES

80       AUDIODEV    If  the  -d  and -a options are not specified, the AUDIODEV
81                   environment variable is consulted. If  set,  AUDIODEV  con‐
82                   tains  the  full  path  name  of  the  user's default audio
83                   device. The default audio device is converted into  a  con‐
84                   trol device, and then used. If the AUDIODEV variable is not
85                   set, /dev/audioctl is used.
