The one difference I think can see between my config and yours is that I have "adjust refresh" enabled and the mode whitelist configured for 1080p @ 60/59.94/50/24/23.976 modes and rate doubling (30/29.97/25 are deliberately omitted so interlaced media works). Your AVR is offering the same so perhaps try that.
Everything is worth checking, but... no, it doesn't work.
Differences are at "dataFormats" section. Missing data formats on LE:
In both cases used format is AE_FMT_S16NE, present on both platforms. What about frames, which is diffrent? Is there a way to change them?
