Thanks.  Through a quick glance at these information, the problem
looks like that both newly appearing "Headphone" and "Speaker" volumes
are set to zero.  Usually alsactl invoked by udev will set appropriate
values for new elements, but in your case, it didn't work by some
reason.

Try to adjust them.  (Note that you don't have to rebuild the kernel
just for this test; pass model=auto option to snd-hda-intel module,
then it'll switch to that mode.)


thanks,

Takashi
