I installed PulseAudio two weeks ago and since then I've been trying to open it and it doesn't.
Does anyone have any solution?
P.S. I have a horrible Speaker set.
PulseAudio is included and configured for you already in Ubuntu by default, you don't have to run it manually. So, if you have some problems with sound, I don't think that is because of PulseAudio. It could be a bug or maybe a hardware problem.
You can check it if is working ok with pulseaudio --check
in a terminal - produces no output on the console except for errors to stderr.
See man pulseaudio
for more informations.
Also, for more help, you can follow this question: Sound problems after upgading to 13.04 and this Sound Troubleshooting Procedure.
You could try to remove it with:
sudo apt-get autoremove pulseaudio
and update and reinstall with:
sudo apt-get update && sudo apt-get install pulseaudio
If this does'nt work, maybe you can find some help in one of these steps:
