Around 3 months ago, I installed LM on my laptop. Everything worked fine, but the audio doesn't work. To make a long story short, I started a thread in this section, and with the help of user MrEen, among others, we tried to solve the problem, but at the end we couldn't, so I decided to wait till LM 19 came out, then I installed it, but the audio still doesn't work.
I'm starting this new thread to see if I can get help from more people, so if you have any ideas, please tell here! Any help will be hugely appreciated.

Some things to consider:
1) My laptop is an HP Pavilion 15-bc008ns, which has, of course, an Intel Sunrise Point-H HD Audio chip.
2) I have tried several Ubuntu-based OSes (Ubuntu, Kubuntu, Ubuntu Mate...), and I have had the same issue, so I don't think this is a LM-exclusive issue
3) I'm currently running LM 19 Cinnamon 64-bit off a USB Drive, so I don't have to overwrite the hard disk for now. I have installed Windows 10 on the hard drive for the sake of compatibility
4) I'm currently running Linux Kernel 4.15.0-23 (Though I just have received the 4.15.0-24.26 update, which I'll install after I post this thread)
5) Here's some terminal outputs for you:
