Although this issue is solved, I give you answers because I don't
understand some of it:

aptitude search alsa-bas
i A alsa-base

> - Are you still a member of the audio group?

groups myusername
myusername : myusername lp dialout cdrom floppy audio video \ 
             plugdev lpadmin vboxusers 

> - What are the permissions on /dev/dsp and /dev/mixer?

ls -ln /dev/dsp
crw-rw---T+ 1 0 29 14, 3 jan   12 07:05 /dev/dsp
            ^^^

ls -ln /dev/mixer
crw-rw---T+ 1 0 29 14, 0 jan   12 07:05 /dev/mixer
            ^^^

I don't understand what are those 1 & 0 ? Where are the 'root audio'
names that usually stands here?
