I have dual boot with Ubuntu 22.04, kernel version: 5.17.5-051705-generic and Windows 10. When using Windows, the fans work silently, while in the case of Ubuntu, it seems that they are set to the maximum speed. In both cases, system is not under load.

I tried to verify what's happening with sensors, but I/O chip of my motherboard (Gigabyte Z690 Gaming X) is not supported by sensors-detect:

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):

I have configured fan speed slope in UEFI and the behaviour under Windows is consistent with it, so I'm trying to understand what happens that Ubuntu somehow "overrides" it.

How is this possible and how can I prevent it?

EDIT: Problem occurs also on Ubuntu 22.04 with kernel 5.15, but doesn't on Ubuntu 20.04 with kernel 5.13

I would like to start music stream to DLNA receiver from Ubuntu 20.04.

I have created DLNA server already through Settings/Sharing/Media Sharing and I'm able to connect to it and play media files using DLNA receiver (some Denon network audio player), but I'm not able to "trigger" music play from Ubuntu side.

I found, that pulseaudio-dlna package would probably resolve my problem, but it looks like the newest supported Ubuntu version is 17.04. What are the alternatives?
