Yes, it seems to be a 'multiple users logged in' thing. Use the sound in one user, then - at some seemingly random point that's NOT while something is actually playing - discover that the sound system is disabled. It's possible that both users have it not working, or one to work and one not to.
Attached is the logs for a second - not using the GP107GL chipset - PC where it's just happened. Sound was working fine in one user (and still is) and disabled in the second. They logged in at about 16:30... ** Attachment added: "logs" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1853374/+attachment/5307739/+files/logs -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1853374 Title: pulseaudio disables GP107GL output every so often Status in pulseaudio package in Ubuntu: Incomplete Bug description: Since upgrading to 19.10, the sound output on this PC stops. Looking at the volume control's 'sound settings', the GP107GL High Definition Audio Controller (digital stereo HMDI 2 output) is disabled. Doing pluseaudio -k restores it.
