i've got ubuntu 16.04 installed , past few days. able play sounds analog audio output (with headphones connected it).

i have hdmi connection , speakers on monitor. today switched audio output hdmi, moment did this, realized analog audio output missing in list late. can not switch analog anymore. though know installed , working.

the funny thing when turn on computer, welcome sound still played headphones (the audio output missing).

i've read couple of posts , questions, here , there, assume sound card not installed, while mine is.

[update]
