The BIOS seems broken, it just sets a single output pin.
You need to try to figure out the pin connections, e.g. via
hdajackretask program. The headphone might work with that.
But the speaker output might need another special handling, and it's
nothing but trial-and-test with the existing quirks for similar
devices. Take a look at sound/pci/hda/patch_realtek.c.
