OK, I just tried this patchset on my Asus P7P55D PRO (VIA VT1828S). Good news is that the analog 5.1 output and microphone input appear to work fine. However I am getting no output on SPDIF optical output at all, the jack doesn't even light up which suggests that the codec isn't powering on the SPDIF port, or something like that.
I've seen a few of these messages in dmesg while poking around with things, they may or may not be related:
ALSA sound/pci/hda/hda_intel.c:683: No response from codec, disabling MSI: last cmd=0x01ef0100 ALSA sound/pci/hda/hda_intel.c:698: azx_get_response timeout, switching to polling mode: last cmd=0x01ef0100

ALSA sound/pci/hda/hda_intel.c:683: No response from codec, disabling MSI: last cmd=0x021f0200 ALSA sound/pci/hda/hda_intel.c:698: azx_get_response timeout, switching to polling mode: last cmd=0x021f0200
I also tested in Windows and SPDIF output works (obviously) with rates up to 192KHz, so I'm not sure why this patch set limits it to 48KHz only..
