Required Packages
First you need to get some missing packages with Synaptic. These packages were not installed by default but are important for getting your sound working properly:
asoundconf-gtkOnce you have all these packages installed, close any application that may be trying to use sound and go to System/Preferences/Sound and set all the preferences from automatic to PulseAudio except Default Mixer Tracks which you should set to your sound card. Go to System/Preferences/Default Sound Card and choose pulseaudio.
Next, right click on the little speaker on the top panel, that is the Panel Volume Control. Click Open Volume Control and make sure it is set to the same thing as the Default Mixer Tracks. Click on Preferences and make sure that Master and PCM and whatever else you want to control are selected. Make sure that any boxes labeled SPDIF or IEC958 are not checked. Close the Preferences box. Push up the sliders in the volume control and make sure the little speakers do not have little red mute marks on them. Go to Applications/Sound and Video/GNOME ALSA Mixer and see if there is anything you missed because sometimes, for some cards, not all the
options are in the Panel Volume Control.
Go to Applications/Sound and Video and select Pulse Audio Device Chooser. This will put a little icon on the panel near the Panel Volume Control. Click on the new icon and choose Volume Control. This will open the Pulse Audio Volume Control. Go to Output Devices and see if your sound card is there, it will be listed as ALSA PCM on front:…(ALC8 via DMA or whatever your sound card is. If you have a usb device it will be listed as ALSA PCM on front:…(USB Audio) via DMA or something like that. Make sure the sliders are up and the device is not muted.
If any of the above is giving you problems, try rebooting.
Now, open Rythmbox and play something. If you have nothing handy just play one of the radio stations, you should hear something. In the Pulse Audio Volume Control/Playback you should see something like this
Rythmbox: Playback Stream and some Volume sliders that you can adjust.
More than one Device
If you have more than one device listed in Output Devices, Rythmbox may be playing in the wrong one if you do not hear anything so right click on the stream and choose move stream and move it to another device.
If you have more than one device and you want to use them all, like a usb headset and your speakers, go back to the Pulse Audio Device chooser on the panel and select Configure Local Sound Server/Simultaneous Output and click the box:
“Add virtual output device for simultaneous output on all local sound cards”
Now you can right click on the stream and move it to your new device. You should have sound from all your sound devices now or at least a clue about how it is supposed to work.
Other stuff
Another thing you may need to do, Check in System/Administration/Users and Groups that your users and root are enabled as members of the following groups:
pulse
pulse-access
pulse-rt
This seems to be a particular problem for some people after getting recent updates.
If you still have problems look in to the following references (They are very good)

Benefits
Separate process: Web apps can hog memory or processor cycles or even bring down the whole browser in extreme cases. By running each app in its own process, we minimize the impact of any mishaps. We can also benefit from operating system tools that less us view the memory/CPU consumption of a specific application.
Minimal user interface: A general-purpose browser UI is not necessary or appropriate for most web apps. It is more efficient to provide a UI that is specific to the application. This also cuts down on UI clutter (hence the term distraction-free browser).
Basic desktop integration: Support of desktop features can make using the app more natural and convenient for end users. This includes the ability to create desktop shortcuts, to place the application icon in the tray or dock and to display pop-up notifications.
Customization: Apps can be run using a shared browser runtime and customized using client-side script (similar to Greasemonkey).
Custom stylesheets can be used to tweak the UI.
