I experience the same problem on another MSI laptop (GE63VR-7RF). I think every MSI ALC1220 laptop suffers from this problem since their pin configuration is the same.
Adding this entry to alc880_fixup_tbl should fix the problem.
SND_PCI_QUIRK(0x1462, 0x11f7, "MSI-GE63", ALC1220_FIXUP_CLEVO_P950)

Thanks for the report.
I'll submit and merge the following fix patch.

Merged now. It'll be included in 5.8-rc2 and backported to stable kernels later.
