Hello guys,

I just upgraded my alsa from 1.0.16 to 1.0.18a (actually I tried
1.0.18 for some days, and got lots of kernel crashes, which apparently
1.0.18a fixes). Thing is that when I try to use my headphones with
1.0.18a they don't work.

I'm attaching alsa-info.sh outputs for both 1.0.16 and 1.0.18a too see
if this helps.

Headphones detection works pretty well, when ever I plug the jack
internal speakers stop working but nothing is coming from the jack. I
can hear an static sounds, so it seems like the headphones are getting
the bias current, but not the signal itself.

Please let me know how can I help you to debug this problem.
