Yep, the 1st generation IONs (including ASROCK ION 330HT-BD) don't support it.

I'm not aware of such a requirement.

Only the first-gen ION chips have that issue.

Phlogi's ION is a 2nd generation one, so it doesn't have the channel ordering issue and HD passthrough has indeed a chance of working.

That wouldn't be enough on 1st gen IONs, as one needs to enable the HBR mode as well, and that is not implemented in ALSA for that chipset and very likely to not be supported by the hardware either.
