Can't get 5.1 surround sound from all of the streaming services

My set up:
Internet and TV Provider = Cox
TV = Vizio E600i-B3
Streaming Device = TiVo Stream 4K with Android TV
Surround Sound system = Sonos Beam with 2 Play 1s and a Sub

TV speakers are set to "OFF" and digital output is set to "Bitstream" per the TV instructions to get multi-channel audio.

Sonos equipment is currently connected to the Optical output of the TV, but I had it connected to the HDMI ARC (HDMI 1) output and I get the same results. I use the Optical because the Sonos can use either output and I need the HDMI ARC connection for a different piece of equipment AND the TV instructions say that Optical can deliver multichannel audio.

TiVo Stream 4K is connected to HDMI 3 and in the Audio setting I have every audio profile turned on.

The test movies I am using are Zach Snyder's Justice League, Godzilla V Kong and Aquaman on HBO Max.

I get full surround from Aquaman and on the title screen the audio is listed as 5.1

I do not get any rear sound from the other two movies and they are listed as Dolby Atmos so it seems that the DD+ is being converted to PCM Stereo 2.0.

The Beam is rated for Dolby Digital 5.1 but it is not rated for Dolby Digital Plus (Atmos).

Is there a setting I am missing that will convert DD+ to DD5.1 for my system?

Also, on the Disney+ app, I get nothing in DD5.1 - everything is in PCM Stereo 2.0.

Since the Beam doesn’t support Dolby Atmos, Dolby Digital Plus, DTS, or Dolby TrueHD, turn those audio formats off on the TiVo and see if that makes a difference.
