Ubuntu 20.04 displays the sound bar on Pavucontrol, but no audio

cn flag

I recently got Lambda Tensorbook with Ubuntu 20.04. I have audio devices installed (screenshots below), but the audio does not work, unfortunately.

I noticed that it's a known issue, so while I didn't understand most of the codes, I tried all the potential solutions I could find online - from sudo apt update to reset/reboot ALSA and PulseAudio to changing element speaker in analog-output-lineout.conf from off to on through /usr/share/pulseaudio/alsa-mixer/paths/, but to no avail.

Whenever I play the audio now, I do see the soundbar move in pavucontrol, but I still don't receive the sound with or without earphones/HDMI cable (photo below). I have spent days trying to work on this problem, but I still could not figure out any solution; thus, I will appreciate any leads on this. Thank you!

I had the exact same situation yesterday, I had no sound right after testing a new webcam. I have tried everything there is in and out of the books, but no success.

Then I had a crazy idea that came out of the blue, and reinstaled the window manager.

apt-get install --reinstall cinnamon

The sound was back. I can not explain why this worked, but it did.

Thanks for your reply! I am not familiar with cinnamon - what do you use it for?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
