My laptop the GE75 Raider 8SE seems to have the same soundcard, I had the same issue.
I created an arch wiki page for it: MSI GE75 Raider 8SX - ArchWiki
But the short of it is, try:
options snd_hda_intel model=lenovo-y530
in /etc/modprobe.d/modprobe.conf.
It should also improve the sound from your laptop speaker.
