Public bug reported:
I have an LG P1 Express laptop and I always had this kind of problem.
It seems tha ALC883 codec from Realtek can be recognised but I have no
sound through speakers. When I connect headphones I can hear sound but
low.
I am using ubuntu 9.10 RC, but i had this problem with 8.04, 8.10, 9.04.
