Dummy output on Lenovo Z50 running 18.04












0















I can't solve the dummy output problem. Audio stopped working suddenly. Here is the output from some of the commands



$inxi -A gives
Audio: Sound: Advanced Linux Sound Architecture v: k4.15.0-45-generic



$aplay -l gives
aplay: device_list:270: no soundcards found...
I tried this



rm -r ~/.config/pulse; pulseaudio -k, but didn't work.



$sudo modprobe snd-hda-intel gives
modprobe: ERROR: could not insert 'snd_hda_intel': Required key not available



Can anyone help me on this
