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! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1952533 Title: [XPS 13 9370, Realtek ALC3271, Speaker, Internal] fails after a while Status in alsa-driver package in Ubuntu: Confirmed Bug description: Sometimes if I run `pulseaudio -k` a few times, sound returns. Sometimes if I run `sudo alsa force-reload`, sound returns. Sometimes if I shutdown and start the laptop, sound returns. This first occurred a few months ago when I was running 20.04, and I upgraded to 21.10 in the hope it would fix the issue. It did not - sound continues to be intermittent.
