Public bug reported: sometimes it's all ok. Other times ubuntu does not recognise the sound card so there is no sound at all. I reboot the system and sometimes sound card is recognised (so i have sound) and fewer times does not -again- recognise the sound card (so I have not sound at all) and I have to reboot again and again untill somehow(??) the sound card is recognised.
