Hi All -\n\nI was hoping you could help me with my Dolby Atmos setup. I am having trouble with the pass-through devices. \n\nTech:\nSamsung TV (Model: UN55MU6290F)\nSonos Arc Sound Bar \nXbox One \n\nI connected the Arc to the HDMI ARC port on my Samsung TV and downloaded Dolby Access app on my Xbox One. I get the following error message when I try to change the Bitstream Format "Your receiver doesn't support Dolby Atmos for home theater". I know Sonos Arc has Dolby Atmos functionality but for some reason, it ends up with this error message. Below are the changes I made but can't get Bitstream Format to move from Dolby Digital. The error message number I get is 0x80bd0038, I called Sonos Support and they couldn't help me solve the issue. \n\nAudio Setup\nHDMI Audio: Bitstream Out\nOptical Audio: Off\nBitstream Format: Dolby Digital \n\nThank you for your help!
