Comment 20 for bug 556663

Hi, It seems I have almost the same configuration of Mefisto. I can get sound from headphones by using alsa 1.0.23 and model=will, still no sound from speaker.
I've posted a question about it here

and their answer was that my card is experiencing the same bug you're trying to solve here.
On the link above you can find my exact configuration. If you need more information (or if I should report a different bug) just let me know. Thanks
