No sound on Lubuntu 18.04 after upgrading from 16.04
by ChristopheW from LinuxQuestions.org on (#4ZF2E)
Hi,
Recently I have updated Lubuntu from 16.04 to 18.04 on my Lenovo G505 laptop. Then I experienced a problem similar to this one https://www.linuxquestions.org/quest...ed-4175659386/, no sound only Dummy Output available in the Output section of pavucontrol. There's no tray icon in the toolbar neither. The sound worked in 16.04.
I followed the advice from the post mentioned above and other forums, like reinstalling pulse, removing Code:~/.config/pulse and restarting pulse, configuring the pulse system-wise but nothing helped so far.
I also tried this
Code:load-module module-alsa-sink
load-module module-alsa-source device=hw:0,2with no success.
Output of
Code:sudo lspci -vv | grep -i audioCode:00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kabini HDMI/DP Audio

pulseaudio[3240]: [pulseaudio] module-x11-publish.c: PulseAudio information vanished from X11!but it got me nowhere so far.
Any suggestions much appreciated.
Thank you,
