audio problems-pulseaudio installation
First I'd like to mention why I'm trying to install pulseaudio.When I installed ubuntu 11.10 I found out that only one of the 2 audio output ports of my sound card was functional,so I had no sound to my headphones.So after many hours of googling I decided to update manually ALSA.

But after some hours result was nothing.So I decided to absolutely remove ALSA and install pulseaudio instead.Unfortunately during the removal procedure I think that I deleted something which resulted to not be able to log into ubuntu.Anyway I solved it using ubuntu live cd and reinstalling ubuntu.So now I'm trying to install pulseaudio together with ALSA which is pre-installed.

Basically my problem now is that when I try to configure the code I get the following warnings:
You do not have D-Bus support enabled. It is strongly recommended
that you enable D-Bus support if your platform supports it...
You do not have udev support enabled. It is strongly recommended
that you enable udev support if your platform supports it as it is
he primary method used to detect hardware audio devices (on Linux)...

my audio hardware(using "lspci -v | grep -i audio" ) is :

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
01:00.1 Audio device: ATI Technologies Inc Redwood HDMI Audio [Radeon HD 5600 Series]

and my souncard is onboard.

thanks for any help.

Ummm, last time I tried Ubuntu, it already came with pulseaudio preinstalled. Is there some reason you think it's not?

EDIT: So I've confirmed that in 11.10, pulseaudio is enabled by default.

Thanks for your help.Probably you are right but again I believe that I should enable D-Bus and udev because as it seems it would not work properly.Also my problem is that my second audio output port still remains "silent" either I use the one or the other programm!

When you tried to compile pulseaudio, and it complained that dbus and udev were not present, it was referring to the headers (which are packaged separately in Ubuntu). That has no bearing on whether or not the version you have installed was compiled with udev and dbus support, which is the case.

Try installing pavucontrol and see if it lets you switch between different jacks.

Think of "pulseaudio" as a mixer. It relies on ALSA (or on any other soundserver out there).
It is a layer between apps and underlying hardware/soundserver.
You can do nifty things with it, like configuring it so if a VoIP call rings the sound of the pr0n will be muted and alike.

There is absolutely no need to compile it on your own.

If a soundcard "doesn't work" it's usually a problem between hardware and ALSA.
Often you can switch between the cards. Try "alsamixer" in the console.

A good point to get all sound cards to work properly is the user docs from pulseaudio
