In fact I simply removed .asoundrc and it works now. I wrote this .asoundrc file following instructions on the alsa-project home page but it was for previous versions of alsa and it is possible that it is no longer compatible. Indeed I felt very convenient to use the dmix plugin and that's why I had this .asoundrc file. Now question is : do you know a good hint to write a correct .asoundrc file ?
