No card was detected, so I uninstall pulseaudio:
sudo apt-get remove --purge pulse audio
Restarted the system. Card was detected, but no audio. I run alsamixer (in Konsole), the volumes are all in high, but nothing. Then I re-installed pulse:
sudo apt-get install pulseaudio
Restarted the system, nothing. Another try with alsamixer, I find a item hided in the right side (pressing right arrow) "Auto-Mute". Highlight it, press down arrow do put it in "Disabled", voi-la, I have sound again.
