User16808742018439021711 (Customer) asked a question.
Dolby Audio Bridge will not configure / output to speaker configuration overheads.
Mac Studio M1 running Tahoe 26.5 and latest Renderer V5.4 installed.
MIDI set to 9.1.6 configuration.
Wide speakers do not output - Top Mid speaker output . Switching outputs give correct output to Top mids. No output to Wides.
Top Front speakers and Rear Speakers no output.
Testing the speakers with the Audient ORIA (Interface) drivers all works as it should
Testing room setup within the Dolby Render in Speaker calibration setup, all speakers respond as expected, the configuration within the MIDI setup makes no difference.
When I check the 7.1.4 within the MIDI app. there is same problem with Height speakers, 7.1.2 works fine with audio to the Top Mid speakers.
The problems seen in the MIDI setup transfer to the 9.1.6 of the Nuendo DAW. causing problems with immersive plugins. Creating Object busses overcomes many problems but not plugins.
Not sure what to do to fix the problem?

Sorry you are running into issues. It seems like there are few things going on here, so I will try to answer them all, but LMK if I've missed anything.
Dolby Audio Bridge is designed to route audio between a DAW and Dolby Atmos Renderer. It's unclear from your message but it sounds like you are trying to use it as the output of Dolby Atmos Renderer?
A core audio output device's output from DAR is not affected by the output format set in Audio MIDI setup, it is configured in the Room Setup window in DAR.
If you are trying to play back encoded Dolby Atmos via a core audio output device from an application (such as Apple Music), the core audio device needs to be 12 or 16 channels, other output widths are not supported by Apple and will revert to 5.1 (see this post: https://professionalsupport.dolby.com/s/question/0D5QQ0000180Buc0AE/apple-music-dolby-atmos-renderer-714-no-object-channels-height)
If you are a trying to use a bed width larger that 7.1.2 (the maximum bed width), you will need to create an object bed (https://professionalsupport.dolby.com/s/article/What-is-an-Object-Bed-and-how-do-I-set-it-up). If you are only seeing the 7.1.2 output of a bed (no wides and only 2 overheads) you are likely feeding the output of that bed to the 7.1.2 bed in DAR due to misconfiguration.
