How do I purge Pulseaudio?

Asked by Lawrence

Dear Members,

I am using Ubuntu 9.04 and I have recently been sent these instructions of how to purge pulse audio in order to install xine:

type the following in a terminal:

sudo apt-get purge pulseaudio

this will remove the packages. The open the system settings, go to the
multimedia option and push the pulseaudio entry to the bottom (it will remain
there, even if pulseaudio is removed)

Then , again on a terminal, type:
rm ~/.kde/share/config/phonondevicesrc

Then restart KDE, it should work.

NOW MY QUESTIONS:

I cannot find what is meant by System, in order to push pulseaudio to the bottom of the list. Pleae explain how I do this in Ubuntu.
Also, how do I restart KDE? I cannot find any program or option called KDE in Ubuntu.

I would also like to know how to install Xine. When I go to Sinaptic Package Manager, and do a search for xine, many options come up, such as xine-ui, xinetd, xine-dbg, ligxine etc, and I am not sure which of those to select in order to install xine.

Thanks very much.

I'd install gxine

its a small player that uses xine as a backend so will install whatever xine needs for you.

Ahh, to find a terminal console try

Applications - Accessories - Terminal

and the type the commands you've been given into the terminal/command window/console but i have to say that PulseAudio serves the sound to the Alsa mixer so removing it might not be a great idea - only do this if you are sure that uninstalling it will help fix your sound. Sometimes uninstalling and then reinstalling something does help get a package to behave :)

xine-ui = User Interface
xinetd = err, i'm not sure about this one lol
xine-dbg = some sort of debugging tool?
libxine = one of the sub-packages that xine will probably need.

Libraries, codecs and other tools can often be used by other packages so they are separated out so that only 1 instance needs to be active in ram&swap even though several packages can then use it simultaneously. It's one reason why linux is often much faster than Windows because using ram more efficiently helps a lot with this. It also means the only 1 package needs to be updated rather than all the packages that might also use the same library or whatever.

Because programs are split up into different packages when you try to install a program through a package manager it will often ask you if it's allowed to install all the sub-programs the main program will depend on in order to function - we call these "dependencies". Often there will be other sub-programs (or packages), libraries, codecs and so on that can be added to increase the functionality of any program that can make use of it. Try installing "xine-ui" and you'll see that many of the other parts, including xine itself, will be in the list of dependencies. I would agree with AP about trying out gxine except that i have a feeling that it's not designed for the K Desktop Environment and so it might drag in a whole lot of other stuff that you don't really need - unless you want to try out the Gnome desktop too ;) Kaffeine and mplayer are also good multi-media players worth trying.

To restart KDE is probably easiest by logging out and in again - perhaps try "Switch User" but just swithc to yourslf and odn't bother really going to a different user at all ;) Of course a full reboot would do the same thing but seems a bit drastic ;) Here's a guide that might be worth dipping into occasionally ;)

Hmmm, i'm not sure what you mean by system either. Perhaps try typing this into a terminal console

ps aux

that should give a list of all the processes running on your machine at that moment. you can search for a particular proces by "piping it through grep" as follows

ps aux | grep firefox

will show at least 2 processes that have "firefox" in their title. Firefox which is open anyway and also the grep'd command itself lol. It's quite handy for finding out a processes id sometimes as that will keep changing each time the process is started.

I'm not sure that's really what you were asking for tho
Good luck again
Tom :)
