First the problem is not present when pulseaudio is stopped. And also, 
we can get sound with 1.0.17rc1 too. So briefly:

1.0.16 + pulse -> works well
1.0.17rc1 + pulse -> works well
1.0.17rc1,rc2 + pulse -> No sound.

It seems that something is broken for these chipsets in either alsa or 
pulse tree. Any ideas for your alsa-{driver,lib,plugins} part?

Thanks a lot.
