Did you try forcing the mode as suggested by Rob Clark in email?

There are two kinds of resolution supported by the EDID information returned by the TV, sort of "VESA" modes and proper "HDMI" modes. Only the proper HDMI modes support piggybacking audio on the link.
I guess the heuristic is to use the highest resolution the TV reports it can handle that the display driver can also handle, and that resolution wins because it's higher than 720p HDMI resolution.
So I think the display driver is doing the right thing according to its rules and what the TV reported.
