Now I get another new problem, I lose the sound:
---------------------------
# /etc/init.d/alsa-utils restart
Shutting down ALSA...warning: 'alsactl store' failed with error
message 'alsactl: save_state:1163: No soundcards found...'...failed.
Setting up ALSA...warning: 'alsactl restore' failed with error message
'alsactl: load_state:1236: No soundcards found...'...done.
--------------------------
Best regards,
