Maximum Channels using ASIO4All Drivers

[Nordo]

I am using a windows 10 laptop (realtek audio) with the latest REW and the latest ASIO4All drivers.
I am trying to test/EQ a 9.1.4 system.
OK,ok, I'm setting up a soundbar (Samsung HW-Q950T). No laughing. (soundbar has latest firmware).

However, only 8 channels are recognised (as well as the two laptop speakers). Therefore a total of 10 channels.
Running a test on each of the available channels indicates that the Atmos channels are not being picked up.

I was wondering if I should delete the laptop speakers (in the ASIO4All control window).
Would that give me the extra channels I'm missing, or maybe the problem is in the soundbar.

Also, for some reason the volume "trims" in the soundbar's adjustments are not working on the L&R mains. But I think that has nothing to do with REW or ASIO4All.

Any ideas?

The additional Atmos channels are not directly accessible, they can only be driven by Atmos-encoded content.

Thanks John (again).

Does anyone know any encoded content that can be downloaded, that would include individual encoded test tones to all available channels?
