Motherboard: Gigabyte AMD FM2+ A68HM-H

HDMI sound out to my home theater via HDMI was working fine for months until a recent system update. I reinstalled Ubuntu 22.04 onto a different drive and HDMI was available. I then allowed the system to fully update and once again the HDMI sound was gone.

As a workaround, I have installed a GeForce GTX 750 Ti and I'm using its HDMI output. The sound is back and HDMI is available once again in the Settings menu.

This is the output with the above workaround installed.

Can you include the output of the `inxi -A` command?

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.
