Hi, thanks for replying. I don't how to tell which alsa version I use !.. "alsa-base" package version is : 10.0.10-4ubuntu4, so it might indicate 10.0.10-4 version of alsa ? Anyway, I have found the solution for my problem, by finding a bug report at ubuntu bugtracker (bug #33719) see https://launchpad.net/distros/ubuntu/+source/alsa-driver/+bug/33719 What I had to do is to add "options snd-hda-intel model=vaio" for the module, namely in /etc/modprobe.d/snd-hda-intel on an Ubuntu box. With this option, everything works fine. However, it would be easier if the option could be avoided (not easy for a beginner to find the trick).
