Ubuntu will not load and gives a screeching sound until forcibly turned off

th flag

I'm running Ubuntu 22.04 and just recently had an update. Now when I turn on the computer, it loads all of the standard computer setup stuff then goes to black for about three or four seconds. Usually at this point, it would show a line of text across the top of the screen and then go into UBUNTU. Instead, it stops at the line of text, which currently reads:

      /dev/sdf5: clean, 434236/30498816 files, 26469425/121964800 blocks
      [   10.488817] snd-au8830 0000:07:01.0: control 3:0:0:Playback PCM advanced proc
      essing:0 is already present

As it sits there frozen, the text lines suddenly start disappearing and reappearing. And with every off and on, it lets out a snap like an electrical charge. At first, I thought it was the monitor frying, but the sound was coming through the speakers.After about 30 seconds I turned it off by holding down the Power Button. Every time I start it up, it reacts the same way.

I've tried getting it to boot off of an installation USB, so that I could enter with "TRY UBUNTU" and run a recovery program. Unfortunately,when I get to that section and press "TRY UBUNTU or INSTALL", it goes to a black screen with a blinking cursor and stays there.

The last thing I've done is press CtrlAltF4 to open a console window and log in. This has been successful, but while I'm in there, I don't know what to do.

Please, somebody help me. Thank you.

I had a similar problem, and this is the workaround https://askubuntu.com/a/1451126/124466. Does that work for you?
I sit in a Tesla and translated this thread with Ai:

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.
