Sound not working in Ubuntu 22.04.01 and also not in Windows if coming from Ubuntu

pg flag

This afternoon I suspended my laptop on Ubuntu 22.04.01 LTS after stopping a video. When I opened it hours later, sound on Ubuntu was just not working. It detects the speakers, settings say they are reproducing sound (via the graphical interface, when I play something in the background) but nothing can be heard.

When I restarted and entered Windows 10, the speakers started making this loud bop sound every second, perfectly timed. It stopped and restarted when I tried playing something with audio. I later on turned off the PC, and when I entered Windows after shutting down, everything was alright. However, changing back to Ubuntu 22.04.01, the loop restarted: no sound, then no sound on windows, turn off, and working on windows but not on Ubuntu 22.04.01.

(P.S.: I tried detecting the devices and changing stuff with pulseaudio and alsa and nothing worked, even reinstalling those)

Can anyone check this out?

(EDIT: After shutting down the laptop, every OS I boot has working sound. If just reboot it and swap from one OS to the other, then it doesn't work - in any)

Thank you!

Update UEFI and, as always when dual-booting with Windows, disable its (Windows) Fast Startup feature.

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.
