[Inspiron 5547, Realtek ALC3234, Speaker, Internal] Playback problem

[Edgard Aspilcueta]

On a fresh install of ubutu 18.04 all sound work (youtube and system sounds) I connected external hdmi monitor with speakers. I switched audio output to hdmi in settings

Then all audio was channeled to external monitor speakers (youtube and system sounds)

Then I disconnected external monitor and did not touch the audio output

Now only system sounds are working. Youtube in chrome does not work. Audio settings says internal speakers.

Firefox youtube has audio normally

After reboot same issue

Seems issue is in Chrome.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1802350

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

gnome-control-center is only the configuration interface, what you describe is that it doesn't automatically switch back when disconnecting the screen, that is on the backend side and not the user UI, reassigning to pulseaudio then
