I always am in Straight Mode and I don't mess around with the DSPs ever. The only way I've been able to get Dolby Atmos is if I turn on the non-existent "Surround back" speakers under the manual setup, but the guy who calibrated my receiver said that this will end up with me losing detail - especially since I have a pretty thorough calibration already for my setup.
Switching "Surround" with "Surround Back" in the settings is a no-go - as "Surround Back" is automatically grayed out if you turn off "Surround" speakers.
Is anyone else who owns a 1050 getting Dolby Atmos decoded using only a 5.1 setup?
5.1 systems can't play ATMOS without height/overhead speakers, the audio track will default to the core TrueHD bitstream.
There are no Back Surround speakers in a 1050 ATMOS setup, it's only a 7 channel AVR, so your choices are 5.1.2 ATMOS or 7.1 TrueHD
ATMOS is object based metadata within a TrueHD bitsream that requires overhead/height speakers to create audio effects above
and around you.
Without overhead ATMOS speakers configured/enabled, that meta data is not extracted from the TrueHD bitstream because it has no where to go.
ATMOS audio decoding requires that you have at least 2 Presence Speakers enabled, (5.1.2) in a Yamaha 1050
For 5.1.2 speaker setup, it's recommended that the F.Presence speakers are configured as overhead in-ceiling speakers.
...but Front Height or Dolby Enabled (up-firing) bouncers will work too. Must be plugged into the F.Presence speaker jacks.
You also must have Object Decoding turned on, then run YPAO so it knows your speakers relative location (distance/crossover/EQ etc.)
Which unfortunately for you, will wipe out your "custom calibrations", sorry but it sounds like your installer/calibrator did not set you up for ATMOS.
OnScreen>Setup>Sound> Scroll all the way down until you get to Object Decode Mode, Set to Enable
