SoundVol plugin for Take Command / TCC / TCC/LE
Version 1.0.0.2 2023-10-16
Charles Dye
Purpose:
This plugin supplies a replacement _VOLUME
variable which will work under Windows Vista and later. For bonus points,
it also supplies a _MUTE variable to
return the mute state, and a SOUNDVOL
command to report or change the master volume and mute state.
(This is really just the sound volume features from my UIStuff plugin, diked out and rolled into a separate little plugin.)
Installation:
To use this plugin, copy SoundVol.dll to
some known location on your hard drive. (If you are still using the 32-bit
version of Take Command, take SoundVol-x86.dll
instead of SoundVol.dll.) Load the .DLL file
with a PLUGIN /L command, for example:
plugin /l c:\bin\tcmd\test\soundvol.dll
If you copy the .DLL file to a subdirectory named PlugIns within your Take Command program directory, it will be loaded automatically when TCC starts.
Plugin Features:
Syntax Note:
The syntax definitions in the following text use these conventions for clarity:
BOLD CODE | indicates text which must be typed exactly as shown. |
CODE | indicates optional text, which may be typed as shown or omitted. |
| Bold italic | names a required argument; a value must be supplied. |
| Regular italic | names an optional argument. |
| ellipsis… | after an argument means that more than one may be given. |
New Commands:
SOUNDVOL — Display or change the
master sound volume.
Syntax:
SOUNDVOL /B /M /O /Q /U volume
/B | beep after changing settings |
/M | mute the sound |
/O | display the current settings on-screen |
/Q | quietly |
/U | unmute the sound |
| volume | new volume level, 0 — 100 |
Unless /Q is specified, the current volume will be displayed.
rem Crank it all the way up:
soundvol /u 100
New Variables:
_MUTE — Returns the master
sound mute state.
Syntax:
%_MUTE
The value returned is 1 if the sound is muted, or 0
otherwise. If the current volume level cannot be determined (e.g.
there is no sound hardware installed), this variable will return
-1.
rem Check whether the audio is muted:
if %_mute == 1 echo The audio is muted.
_VOLUME — Returns the
master sound volume level.
Syntax:
%_VOLUME
The value returned is in the range 0 through 100. If the current volume
level cannot be determined, this variable will return -1.
rem Display the current master volume level:
echo The master sound volume is at %_volume.
Startup Message:
This plugin displays an informational line when it initializes. The
message will be suppressed in transient or pipe shells. You can disable it
for all shells by defining an environment variable named NOLOADMSG,
for example:
set /e /u noloadmsg=1
