sound from multiple apps

I had experienced the exact same problem.  When Rhythmbox is playing a song,
no sound output came from Firefox (Youtube or any Flash site).  Also, AFAIK
GMail uses Flash for audio alerts (not for other parts).

I guess the problem is due to lack of integration of Flash Player with
Pulseaudio (not an Ubuntu fault).  The workaround is very simple.  In System
->Preferences -> Sound choose ALSA for all options (except may be for
"Device" under "Default Mixer Tracks").  This fixed it for me.  Hope it
fixes it for you too.  Ho[e some developer can comment on whether the
problem is due to non-integration of Flash player with Pulseaudio.

We choose the brand of our Mobile Phone, Motorbike, Car, Shirt, Shoe, Bread,
etc. Then why not the brand of our OS too?

Pre-loading and forcing Vista on new laptops kills consumers' choice. Fight
for choice of OS just as there is for the Hard Disk capacity in new laptops.
