The GStreamer properties applet offers four drop down
menus spread over two tabs. There are two drop-menues for
audio and two for video. These choices set the default for
most GNOME applications for output and input of Sound and
Video.
Looking at the screen for setting audio options you
notice that the two sections are called Default Sink and
Default Source. These are terms used in the GStreamer
framework that GNOME uses to describe where data is sent and
where it comes from. The Default sink is in other words where
GNOME apps should output their sound, while Default source is
where the sound comes from.
The reason you might want to alter these settings is
because under Unix there are many different audio systems and
sound server which you might want to output to. For instance
on Linux popular alternatives are the PulseAudio sound server
or ALSA.
If you wish that your GNOME applcations output their
sound to the PulseAudio sound server you set the Default Sink
to use PulseAudio. And if you wish that your GNOME
applications which has sound recording capabilities use the
ALSA sound system, choose ALSA as the Default Source.
As mentioned elsewhere in this user guide. These setting
are meant for as a tool for advanced users who have
specialized need. As an ordinary user, you should not need to
set these as the vendor of your distribution should have set
them to sensible defaults for you.
