Rhythmbox stops streaming audio

[Antonio M]

when I use Rhythmbox for listening to radio stream, streamings stops
suddenly and I have to push play button to have it back. And when it
happens I see the line for connection becoming blue but only in the
first part and then stops.
I suppose that it is something conencted to pulseaudio or to the audio
driver  : I am using HDA intel and system is a F11 updated this
morning.
Running pulseaudio-0.9.15-17.fc11.i586
Why pulseaudio-0.9.17 is not available to F11???
