Headphones only playing back Left and right channel in 7.1.4
MacBook Pro M2 Ventura 13.2.1, Pro Tools 23.6.0.110, Dolby Atmos Renderer 5.0 using Dolby audio Bridge. Peripherals is connected and LTC works. Using dolby audio bridge in the playback engine.

Hi, Just getting into the Atmos renderer. My problem is through the headphones I can only hear L and R channels. No other channels. I have watched several videos on setup as well as articles, and cannot figure out what I am misconfiguring. It is getting to the renderer. I am only using the bed for now. Could really use some help.

    Hi,

    It looks like you are only using headphones, in which case you will want to use headphone only mode (selected in Renderer preferences).

    If headphone only mode is not selected, the Renderer will default to a 7.1.4, output, which is why you are only hearing L R (the first 2 channels of 7.1.4), as your headphones only have 2 channels. As you can see in your own screenshot, the headphone render output defaults to outputs 127 and 128, which are not available in your selected output device.
