Thanks for the update!

When I load hdac and snd_stel I get the following on dmesg:

hdac0: <Generic High Definition Audio Controller> mem
0xfebf8000-0xfebfbfff irq 16 at device 27.0 on pci0
hdac0: Output Streams: 4, Input Streams: 4, Bidirectional Streams: 0
hdac0: CORB Size: 256, RIRB Size: 256
hdac0: <audio> at device 0:1 (no driver attached)
hdac0: <modem> at device 1:2 (no driver attached)
stel0: <Generic High Definition Audio Device> on hdac0

The exact HDA device or codec or chip (or whatever the right term is here)
is a Realtek ALC880, or at least, that's what ALSA tells me on my gentoo

The devinfo -rv output:

hdac0 pnpinfo vendor=0x8086 device=0x2668 subvendor=0x1043
subdevice=0x1173 class=0x040300 at slot=27 function=0 handle=\_SB_.PCI0.AZAL
    I/O memory addresses:
  stel0 pnpinfo vendor=0x10ec device=0x0880 revision=0x08 stepping=0x00
type=0x01 at codec=0 node=1
  unknown pnpinfo vendor=0x14f1 device=0x2bfa revision=0x00 stepping=0x00
type=0x02 at codec=1 node=2

(I hope this is all you needed)
