The realtek: lines don't appear to affect NID 0x17 at all.  Instead,
they say:

ALSA sound/pci/hda/patch_realtek.c:1154: realtek: No valid SSID, checking pincfg 0x40178e2d for NID 0x1d
ALSA sound/pci/hda/patch_realtek.c:1170: realtek: Enabling init ASM_ID=0x8e2d CODEC_ID=10ec0272
ALSA sound/pci/hda/patch_realtek.c:1111: realtek: Enable HP auto-muting on NID 0x21

And, as I said, I get no sound output with this..
