Do you get sound output if you plug in speakers or headphones into the
headphone jack? I had a problem with my Dell Vostro 1400, where the
laptop's internal speakers didn't output sound, but the headphone jack
worked fine. Supplying the model=5stack option to the snd-hda-intel
module fixed the problem for me. There could be something similar for
your particular model...
