No Audio with Ubuntu 10.04 Beta2 Live Session

[Nicola Jelmorini]

Binary package hint: pulseaudio

I'm not sure if this is actually a Pulseaudio problem, or an ALSA problem. Anyway, I'm testing the last Ubuntu 10.10 beta 2 Live and I can't hear nothing. No speakers audio, no headphones audio. If I open the sound Preferences I can see that even the internal microphone is not detected.
I'm sure that the audio on my laptop was well functioning with the Ubuntu 10.10 beta 1.
