Did you upgrade to 16.10, then to 17.04 and then to 17.10?

Alexander (alexanderlevdonsky) said : #5

From 16.04.

Alexander (alexanderlevdonsky) said : #6

16.04 -> 17.04 -> 17.10

Try:

killall pulseaudio; rm -r ~/.config/pulse/* ~/.pulse*

wait 10 seconds, then reboot.

Alexander (alexanderlevdonsky) said : #8

I did it already. And reboot too.
pulseaudio seems not killed.

 -
$ sudo killall pulseaudio; rm -r ~/.config/pulse/* ~/.pulse*
rm: cannot remove '/home/huduguru/.pulse*': No such file or directory

$ ps fax | grep audio

 It seems Intel integrated HDMI video/audio is not supported in 17.10, isn't it?

If you use:

alsamixer

Are all levels maxed and unmuted? Use M to un/mute. ESC to exit and cursor keys as you expect. Use F6 to change the device you are manipulating.

Hello. System reverted back to 16.04. Case closed.
