Audio passthrough on roku ultra device

I have a Roku ultra 2020 as well as a Vizio 5.1 sound system. The roku audio settings allow me to have different choices: PCM, pass through, DD Plus, etc. For some reason only passthrough allows my side speakers to work. Anyone know why that is or if I should be doing something different? Thanks.

You want "Auto passthrough" - "Auto detect" transcodes/converts all non-DTS output to the highest detected Dolby level (E.g PCM MAT 2.x/Atmos, or DD+/Atmos, etc etc) of the connected device (regardless of # of channels etc - you dont want that).

Just leave it at auto-passthrough unless your audio drops, then you should toggle it to auto-detect, then back to auto-passthrough.
