Comment 2 for bug 1802350

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.
