It looks like internal speaker should be nid 26, but question is what should I configure here... no idea how to send sound output there, even after some reading of 'man snd_hda'. Maybe I need more reading. Output of command 'sysctl dev.hdaa' is in attachment... So, I need some kind of enlightement, what I should do, now. Regards, Milan
