After supposedly upgrading to Ubuntu 22.04 from 20.04.4, my laptop's system monitor listed my upgrade as the old one, 20.04.4. Today, I noticed that the headphone output was not delivering audio to the headphones. What I noticed was that the internal speakers were working normally, but the speakers were not as powerful. The first picture shows the sound applet screenshot:
And the second screenshot shows the test speakers output display, which did not indicate sound coming from the headphone output:
Before Canonical began the partial upgrade of 20.04, everything was working without a hitch; the system sent error messages saying that Firefox snap integration would be only partial on my computer, then when it completed the snap updates, the notification said everything was up to date. I am supposed to have a brand-new Ubuntu 22.04, and I am still waiting for it to happen. This is the first time my system has suffered technical problems after an upgrade, Ubuntu has always given me dependable updates. So what is causing my headphone output to not work correctly? I live in an area where I don't have any qualified Linux techs listed, so it's a frustrating thing to feel stranded. Thanks for sharing, I can still use my machine, even without the headphones!
