OK, then could you alsa-info.sh output?
The situation in the upstream has changed since we have a lot more AMD-specific HDMI codes in the latest driver for 3.13 kernel. So, it's not only a matter of snoop flag.
I was specifically trying to get clarification on which parts needed the snoop flag. Is there some other larger issue? From the feedback I've seen lately, audio has been working pretty well on AMD GPUs with Anssi's patches.
That's why I started asking :) The recent code should cover known issues of AMD HDMI codecs, at least. But if there is a new chip, we'd need to test and add the corresponding entry.

The card shown as "Generic" is actually yet another AMD HDMI chip. And this should work without the snooping. Unless you hear any audible problems, no reason to fix this one.
Another "HDA ATI HDMI" one is tied with a different graphics unit. I don't know what hardware configuration you have. Do you have multiple AMD graphics cards? Basically each HDMI audio entry is tied with the dedicated graphics chip (board). You wanted to play back via this HDMI and it didn't work?

The ATI card did not show up as "ATI", but the other ATI card without HDMI did: http://thread.gmane.org/gmane.linux.alsa.user/37732.
Anyway, let's close this thread:
--8<---------------------------------------------------------------->8-- ALSA: hda: add device IDs for AMD Evergreen/Northern Islands HDMI
The device IDs of the AMD Cypress/Juniper/Redwood/Cedar/Cayman/Antilles/ Barts/Turks/Caicos HDMI HDA controllers were missing for some reason. Add them so that the name shows up properly as "ATI HDMI" instead of "Generic", and so that the driver does not try to detect nonexistent codecs.
According to Takashi's tests and the lack of complaints, these devices work fine without disabling snooping.

Well, there is no actual behavior difference between AZX_DRIVER_ATIHDMI and AZX_DRIVER_GENERIC about AMD HDMI chips. The codec-probing is pretty same. The only difference in the current code is the driver name string and the fallback of number of streams, but the latter is valid only when GCAP register doesn't give proper values, and it shouldn't happen with a proper chip.
That being said, the entries weren't added intentionally just because they aren't needed to be added explicitly. The generic entry suffices from the functionality POV.
But it seems that people misunderstand, so I think it's fine to apply your patch to give a more clear name.
