Hello,
It always seems like out of the box, Linux distros need help improving on the sound quality. On my previous EOS install I attempted this but messed up a lot of stuff along the way.
After doing some searching and reading, I see PulseAudio is a frequently used option, but I thought I would simply ask the community, what steps have you taken for improved sound quality?
I donāt quite understand you. What is meant by āsound improvementā? 
My apologies, that was a bit vague on my part. My sound seems flat and ātinny.ā Iām confident that my laptopās features provide better sound quality than I am hearing so Iām trying to learn what are my best options for getting better sound: is it PulseAudio or something else for example?
Or, maybe Iām just expecting too much - also quite possible! 
I use this approach for my ThinkPad: https://wiki.archlinux.org/title/Lenovo_ThinkPad_T14_(AMD)_Gen_4#Speakers
Maybe it can be used for MSI laptop also.
It seems to me that you should not expect āmiraclesā from any integrated laptop solution. Personally, I use an external DAC for music.
Either using Alsa (if additional sound processing is needed) or I immediately output the signal to the DAC if native DSD playback is needed.
I can only draw attention to the easyeffects package, which has many possibilities for some sound improvement.
P.S. And I use pipeware
