Public bug reported: I'm using ubuntu 20.04, I recently upgraded from 18.
I have nvidia video card, connected to HDMI TV which outputs sound. I think the sound will not work sometimes after boot up, sometimes it does work. But it definitely does not work when ubuntu goes to idle. As soon as ubuntu goes to idle and screen starts to fade, sound will disappear. Funny enough, if I play a game from emulator MAME, MAME game will bring sound back, and all my youtube and other games sound will work.
