In case of tv not supporting eARC and Bose Soundbar 900 does not have a HDMI in, will streaming audio from Apple TV 4K via bluetooth to Soundbar HELP?? Can I experience Dolby Atmos Audio that way??? Please help
Bluetooth is always stereo, not Atmos.
If your TV does not have eARC the only way to get Atmos out of Apple TV (and by extension lossless sources from Blu-Ray players) would be from products like HD Fury Arcana. It is pricey but certainly less than buying a new TV.
i believe you can still use optical cable to make it work for surround 5.1 , certainly won't be atmos . the bose 900 have its own issue even with tv with arc. if you check reddit alot of ppl in community owning this model are complaining cut out or no sounds with its hdmi arc.
