+/*
+ * Purpose: Sources for the ossmix command line mixer shipped with OSS
+ *
+ * Description:
+ * The {!xlink ossmix} program was originally developed as a test bed
+ * program for the new mixer API. However it has been included in the
+ * oss package because there is need for a command line mixer.
+ *
+ * Due to the history ofg this utility it's probably not the most
+ * clean one to be used as an sample program. The {!nlink mixext.c}
+ * test program is must smaller and easier to read than this.

+NAME
+ossmix - Open Sound System command-line mixer program.
+
+SYNOPSIS
+ossmix [-d <dev#>] [-achqD] [control name] [value]
+
+DESCRIPTION
+ossmix is a simple command-line mixer utility that is used to display the mixer
+settings of physical and virtual audio devices. OSS version 4 has an extended
+mixer API which supports some device specific features that may not available
+using other mixer applications.
+
+OPTIONS
+-D Display device information.
+-a Dump mixer settings for all mixers (normal format).
+-c Dump mixer settings for all mixers (command format).
+-h Display usage information.
+-q Quiet mode.
+-v[1|2] Verbose mode. -v2 prints more detailed infoamation than -v1.
+ctrl# value Change value of a mixer control.
+<no arg> Display current/possible settings.
+
+USAGE
+ossmix without any arguments displays the current settings of the
+default mixer device (usually the motherboard sound chip). This
+printout can also be used to find out the supported control names and
+their possible values. Currently all controls accept an ON/OFF value, a
+mono value (0 to 100) or a stereo value (left:right where both channel
+volumes can be between 0 and 100). The value can also be expressed in a
+relative form (e.g. +1 to add 1 to the previous volume). An ON/OFF control
+can also receive a TOGGLE value. If a control has a name in quotes following
+the normal output, than the name can be used instead of the control when
+setting a value.
+
+The following is a sample printout produced by ossmix:
+
+ Selected mixer 0/Creative AudioPCI
+ Known controls are:
+ vol <both/leftvol>[:<rightvol>] (currently 50:50)
+ pcm <both/leftvol>[:<rightvol>] (currently 50:50)
+ speaker <monovol> (currently 21)
+ line <both/leftvol>[:<rightvol>] (currently 32:32)
+ line.rec ON|OFF (currently OFF)
+ mic <monovol> (currently 16)
+ mic.rec ON|OFF (currently ON)
+ cd <both/leftvol>[:<rightvol>] (currently 100:100)
+ cd.rec ON|OFF (currently OFF)
+ pcm2 <both/leftvol>[:<rightvol>] (currently 75:75)
+ line1 <both/leftvol>[:<rightvol>] (currently 32:32)
+ line1.rec ON|OFF (currently OFF)
+ line2 <monovol> (currently 32)
+ line2.rec ON|OFF (currently OFF)
+ line3 <monovol> (currently 0)
+ line3.rec ON|OFF (currently OFF)
+ mic.micboost ON|OFF (currently ON)
+ mic.micbias ON|OFF (currently ON)
+ mute.pcmmute ON|OFF (currently OFF)
+ mute.pcm2mute ON|OFF (currently OFF)
+ mute.micmute ON|OFF (currently OFF)
+ mute.cdmute ON|OFF (currently OFF)
+ mute.linemute ON|OFF (currently OFF)
+ mute.line1mute ON|OFF (currently OFF)
+ mute.line2mute ON|OFF (currently OFF)
+ mute.line3mute ON|OFF (currently OFF)
+
+SELECTING MIXER DEVICE
+It's possible to select the mixer device by using the -d<mixernumber>
+command line argument. This argument (when used) should be the first one
+on the command line. By default the mixer number 0 will be accessed.
+To find the available mixer devices, type ossinfo -x and look
+under the Mixers heading for available mixer devices.
+
+CHANGING MIXER SETTINGS
+Changing the values is done just like with the original "mixer" applet.
+For example:
+
+ ossmix pcm 50:60
+
+The above sets the pcm control (audio playback volume) so that the left
+channel volume is 50 and the right channel volume is 60. With just
+"ossmix pcm 50" the both channel volumes will be set to 50.
+
+In addition to the old mixer there are now some (usually ON/OFF) settings.
+These settings are device specific and don't work with all soundcards.
+The easiest way to find them out is to start ossmix without command line
+arguments (other than -d#).
+
+Some control names contain a dot ("."). This dot is required when changing
+the value. For example: "ossmix -d0 mic.micboost ON".
+
+."USING OSSMIX WITH A MIDI CONTROLLED MIXER
+."The ossmix program has capability to listen MIDI main volume controller
+."messages from a MIDI port. You can assign a ossmix control to each MIDI
+."channel. After receiving a channel main volume change message ossmix will then
+."change the mixer level of the volume control assigned to the channel. In this
+."mode ossmix will not exit (you need to kill it manually).
+."
+."This mode is very useful if you need to make several rapid mixer changes
+."simultaneously.
+."
+."To use this mode you need to give the MIDI device file and a list of the
+."volume sliders on command line. For example:
+."
+ ."ossmix -d1 -m/dev/midi00 vol mic pcm line gain.out1/2 gain.in3/4
+."
+."After that the MIDI channels will be assigned in the following way:
+."
+ ."Ch 0 = "vol"
+ ."Ch 1 = "mic"
+ ."Ch 2 = "pcm"
+ ."Ch 3 = "line"
+ ."Ch 4 = "gain.out1/2"
+ ."Ch 5 = "gain.in3/4"
+."
+."Other MIDI channels (6 to 15) will be ignored.
+."
+."Only mono and stereo slider type controls can be assigned to MIDI channels.
+."Both stereo channels will be set to the same volume (there is no balance
+."support).
+."
+."After starting ossmix you should move the sliders on the external fader box
+."so that ossmix can figure out their current settings.
+."
+."At this moment only MIDI fader boxes that send only main volume change messages
+."are supported (any other MIDI data will make ossmix to behave incorrectly).
+."For example the FM3 MIDI Mixer (AKA "FaderBaby") by JLCooper is compatible
+."with ossmix.
+."
+
+EXAMPLES
+
+ ossmix vol 50
+ Set the vol control volume to 50. If the pcm control is a stereo control,
+ than both channels will be set to 50.
+
+ ossmix vol 50:60
+ Set the vol control so that the left channel volume is 50 and the right
+ channel volume is 60.
+
+ ossmix vol +2
+ Raise vol volume by 2.
+
+ ossmix -- vol +2:-2
+ Raise the left channel volume by 2, and lower right channel volume by 2.
+ The "--" is needed on some systems so that the "-2" won't be mistaken for
+ a parameter.
+
+ ossmix micboost ON
+ Set micboost to ON.
+
+ ossmix micboost TOGGLE
+ Toggle micboost.
+
+ ossmix mplayer +2
+ Raise mplayer volume by 2. This would only work if mplayer is using the
+ virtual mixer.
