The hda sound codec is somewhat of a morass with manufacturers, particularly laptop manufacturers, hard wiring the chip in different, non-standardize ways. Have you tried internet searches for your particular device? How about FreeBSD/NetBSD support? Searching Linux/alsa compatability might let you know about funny wiring. I put Arch Linux on an old laptop for a neighbor and what was detected as speaker outputs actually was the headphones jack. I also installed OpenBSD on a Via Viotech 3100+ motherboard (would not support 2 SATA drives but would support 1 SATA and 1 IDE) only to have the hda sound not work. Rather than fight with it, I put in FreeBSD and sound worked out of the box.
