I can't get sound from the console in OBS.

I connected the console (Retroid Pocket 5) via a USB-C HDMI cable to an external capture card (AVMatrix UC1218-4K), and connected it via USB-C USB-C to a Mac Book Air M1.
Adding a Capture card device in OBS. OBS displays video but no audio. Nothing appears in the mixer. How to fix this problem?

Capture card device - Inactive. Why?

The Loopback program shows that audio is running on the computer. But the OBS mixer has zero response to audio.

The problem is definitely not on my side. I tried to shoot a video in Streamlabs and there is sound.
