Comment 3 for bug 1952533

I have the same problem. It started late in 2021, I think. I have no damn clue what's going on.

Sound often works when booting from "off". It often breaks if I put my laptop to sleep and wake it. It may break at other times?

When the sound stops, it stops sound on the whole machine. I have a USB-A to 3.5" headphone adapter and I thought I could use that because it is separate hardware, but, no, that doesn't work either.

I've tried blacklisting the snd_hda_codec_realtek module, but it still happens.
I've tried installing the original OS (Ubuntu 18.04 from Dell) and it still happens.

Maybe I zapped the audio card with static electricity and it stopped working? But why would that affect the USB-A dongle?

Maybe there was a firmware update from Dell that changed its behavior?

I'm stupified. But I need audio. I love Linux, but I'm thinking of abandoning Linux and going to MacOS, because I need working audio!
