There are a few special model option values:
+- when 'nofixup' is passed, the device-specific fixups in the codec
+ parser are skipped.

the latest alsa driver allow you to skip the pin fixup

The STAC9227/9228/9229/9230 are a family of Theater Quality 8-channel audio CODECs that enable systems with 7.1 audio or 5.1 audio playing simultaneously with VoIP or another stereo audio stream

if pulseaudio must need a headphone volume control, you may try remove

/* Dell 3 stack systems */
- SND_PCI_QUIRK(PCI_VENDOR_ID_DELL, 0x01dd, "Dell Dimension E520", STAC_DELL_3ST),

and disable the grey jack node 0x14 (lost 7.1 support) but you can use independent HP by specify hint
