1/ after boot, the sound is ok, but after some time of utilisation (only web,
play music sometimes, and vi) the sound is no more available (it never was a
failure while playing)
Connections and volume level are ok and unchanged when it fails.
2/ :~$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf0600000 irq 22
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xf0210000 irq 17

4/ i did `ps -efl` just after boot, and after the sound failure, here is the
diff :
< is ok with sound just after boot
> is after sound failure
84d83
< rhythmbox --sm-config-prefix /rhythmbox-38EFe1/ --sm-client-id

5/ lsmod gives the same loaded modules, just the number (count of use?) changes
:
$ diff nosound-lsmod-soundok-boot nosound-lsmod
