Probably some ALSA module or codec firmware is missing.
Look for errors in syslog and provide some information about what sound
codec is onboard your laptop mobo:
    $ sudo journalctl -b

Use "/" key to search for a string. Ex:
    /audio
    /hda
    /sound

the / is used in a lot of cases (editors, web browser,...)
I don't understand what search key you are talking of.

   nothing new in syslog
   here are the outputs for the journalctl calls
   Do you see there something interesting?
   For me, it's not very useful.
