the new kernel module added two new regulators "speakers" and "headphones",
and they are both set to "0" by default!
Additionally kmix and some other GUI might not show them as well as alsamixer,
but just start "alsamixer -c0" and all sliders appear. Now you can set them as
you want, and now you can hear sound playing again.
A great "thank you!" in this matter to Jonathan Nieder and Takashi Iwai, ho
helped me, to find the solution!
So ist was just PEBCAK! The bug can safely be closed!
Thanks for all the help!
