xtmix is an interface to the mixer part of Linux's sound device driver.
The program shows left a few sliders controlling the input channels. Using the left mouse button, you can change the volume of these channels. Using the right mouse button you can control the right and the left channels seperately. There may be some channels not supporting stereo (e.g. MIC). The pictures beneath the sliders symbolize the devices connected to these channels.
The "LEDs" on top of some pictures indicate the recording source. This source can be changed by clicking on the desired picture.
On the right side there are some dial buttons controlling main volume, balance, bass and treble (the latter two not on all sound cards). They can be moved using the left mouse button.
To quit press "q" or use the delete function from your window manager (i.e. in most cases: double click the title bar's left button).
This mixer can be started with the -launch option to supply a "launch window". In this mode, only a small window containing the main volume control pops up. This control can be manipulated with the left mouse button. Pressing the right mouse button reveals the main mixer window, pressing it a second time hides it again. This launch window is meant to be swallowed by a window or desktop manager. The launcher window's name is "xtmix-launcher", this has to be specified in the window manager's configuration. See EXAMPLES for a configuration with fvwm.
This is a "KDE aware" application. If it detects a running KDE system, it uses its color scheme and also responds to color change requests. Swallowing the launch window in KDE is not recommended, because KDE blocks input to swallowed windows.
Specifying any other option will print a short usage summary as well as some compilation information.
XtMix*cd.slideColor: skyblue
produces a skyblue slider for the cd channel (yes, this looks really ugly).
You may use editres (1) to find out about the widget structure and the associated resources. The resources asociated with the mixer's options are mixerDevice, noFilters, launcher, launcherBackground, launcherLabel and ignoreKDE.
If you own a card where the bass/treble dials are not functional, put this line in your $HOME/.Xdefaults (or in the global app-defaults file):
