Can't get multi-channel audio from Macbook to my soundbar/receiver

I'm trying to use REW for the first time but failing very early in the setup process. I'm on a macbook (a new M1) and connecting to my Sennheisser soundbar using a USB-C hub that has HDMI output on it.

When I try to go into the Midi mixer app on Mac, the output only shows 2 channel with no option of multi-channel. So in REW when I try to "check levels" there's no sound coming from my speakers (presumably because of lack of multi-channel and the LFE channel isn't being passed).

Someone else must've had this issue?

Does Audio Midi Setup not show a multichannel option amongst the formats for the output? If not the hub may not support multichannel PCM over HDMI.
