Are you sure both are the same kernel but just one commit reverted?
I retested, yes.
Thanks for confirmation!
With or without the revert, model=auto disables sound completely, and I get this in dmesg:

I played with model=intel-mac-auto and model=intel-mac-v3 but it had no effect, i.e. same as without the model= parameter.
So, without model=auto the problem is that I get the output on both the internal speakers and the headphones, and this is fixed by reverting the commit.
Then this is really a PCI SSID conflict, and reverting the patch is the right fix (and possibly addition of check of codec SID).
I fixed it now on my tree, and will include it in the next pull request.
thanks,
Takashi
