Linux Mint, Ubuntu, install newer kernel with Ubuntu mainline kernel

Setting up the latest kernel versions on Ubuntu and similar systems - here's how.
I bought an Acemagic AX 15 notebook and wanted to install Linux, more precisely Linux Mint, on it. Due to the modern hardware of the notebook, I expected some challenges, and indeed some problems occurred.
Neither the sound nor the brightness setting worked correctly. This was due to the new Intel N95 processor and its chipset. Can an updated kernel help here? The answer is clear: Yes! But how does one carry out this installation? This is where the "Ubuntu Mainline Kernel" comes into the picture.

Thank you! This helped me fix the sound on my HP laptop. As a side note, it would probably be good to create a Timeshift snapshot before updating the kernel, right? Timeshift should be making hourly snapshots when running Linux Mint by default anyway but probably still a good idea to make sure you dont lose any files if the new kernel doesn't work
