If your system has multiple audio devices, then they will be numbered
0, 1, etc. The default will be 0, but that might be wrong. To test this,
you can simply cat an audio file at the devices to see which
one works, for example
cat /usr/demo/SOUND/sounds/train.au > /dev/sound/1
To fix audio output for most applications that have no way of selecting
the audio device, simply replace /dev/audio,
/dev/audioctl, and /dev/dsp with symbolic links
that point to the working device.
To get GStreamer, and applications using GStreamer for audio output, to
use the non-default audio device, set the environment variable
AUDIODEV to the working dsp device, eg /dev/dsp1.
If you're running MATE, then there's a volume control, and some audio applications have their own volume controls. For anything else you can adjust the volume from the command line:
/usr/bin/audioctl set-control volume 50
where the volume is between 0 (muted) and 100 (full volume).
If you see warnings or errors about GStreamer being unable to load its plugins, delete the registry file(s) in $HOME/.cache/gstreamer-1.0.
The Sakura terminal is probably the best all-round terminal. To change settings, start up one copy, right-click to get into the settings menu. Once you have it the way you want, close that instance of Sakura to save the settings.
You can add the Whisker Menu by right-click on a panel, got to Panel, Add New Items.
The background wallpaper is under Desktop Settings. (Just right-click on the background.)
If you want transparency, and you're lucky enough that your combination of graphics card and Tribblix manages to support it, go to Window Manager Tweaks and it's under the right-most tab, Compositor.
