i already did that, and my username is in that list,
freddy adm cdrom sudo audio dip plugdev lpadmin pulse pulse-access sambashare
rebooted the machine and still is not working.
Also, there is no /proc/asound directory created by default, so my ubuntu is not recognizing my external audio card, eventhoug i have already disabled on the BIOS the internal one.
my sound preferences shows a dummy card, and i have no sound at all..
any other help, tip, would be appreciate.
