Hi. I’m new at Ubuntu Discourse but I use Ubuntu for a couple of years. Unfortunately I have to use more the Mac because of my work but I really enjoy using Ubuntu. Lately I’ve installed it in a machine that I have Windows 10 on it, so I created a dual-boot with Ubuntu 20.04 and I’ve been trying to use it more often and I realized that the audio is lower on Ubuntu. And when I play videos I have glitchy screen. Unfortunately I couldn’t take screenshots of the videos because when I do it it doesn’t capture the glitches.
About the audio I’ve installed a software called PulseEffects but it didn’t worked. So I followed the instructions I’ve found in this page. I’ve done this because the computer I have dual-boot is a Lenovo Ideapad s145 with Dolby Audio support so I thought those instructions would give me the ability to “unlock” the Dolby Audio feature. But it didn’t worked either.
This is the output of lspci command:

Is this is a real issue or it only affects me? Do I have a poor hardware?
Thanks for the attention!
