Running "pulseaudio" and "alsa" together.

[Nathanael Noblet]

Might I suggest that you look for documentation about configuring 
pulseaudio on an XO-1 with F14? Or just basic pulseaudio configuration? 
I'm guessing that the issue is there more than anywhere.

Also I'm curious - the gstreamer-plugins-good is provided by Fedora 
itself? Is the XO non-x86 based? Etc... I'd look into why the pulseaudio 
plugin isn't included in the gstreamer package. If the version of Fedora 
installed isn't *stock* fedora, then it is entirely plausible that 
somehow pulseaudio has issues on the XO and so the distro developers 
made sure that the plugin wasn't built since it would never be used... 
If it is stock fedora, find the maintainer (though honestly with F14 
being EOL for awhile now they may not respond..) and ask them if there 
is a reason why it isn't included etc....

Just some thoughts. Basically though the problem you are describing 
isn't in any way related to gstreamer and entirely related to setting up 
pulseaudio on a system.

Just some thoughts.
