I’ve been at this for a while now waiting for the release of kernel 5.15 to release to reinstall ubuntu 20.04 and test the kernel to see if it resolves the no sound issue I have over HDMI.

I run pavucontrol and can see HDMI devices, I click the test sound, and see the sound monitor line move in the sink, indicating the system responds, however no sound comes out the soundbar.

I've tried the usual rm * of the pulseaudio files and pulseaudio -k.

Any other ideas to try to get sound?

I understand that very recent releases have made changes that re probably causing your problem. I have the opposite problem:my sound is being routed to hdmi rather than the speaker,

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.
