Hello,

I have a 5.1 setup with the Arcam AR 390, and I want to do a REW measurement.
On the AVR a have selected the HDMI port GAME, with a long HDM cable a connect it with a thunderbolt hub to my Mac. The UMIK-1 is also connected tot de HUB.

With REW i can measure the front L+R, but I can't choose LFE of surround speakers.
In the AUDI/MIDI setup I can only select 2 output channels (stereo) and no 5,1 setting.

What I'm doing wrong ?

The AVR may need to be set to a particular processing mode to support multi-channel PCM, or that HDMI port may not support multichannel PCM but another might.
