Struggling to use the just-arrived AVerMedia Live Gamer Ultra 2.1 and OBS to play PS5 games on an iMAC with M4 chip. I have set OBS to use the card as its audio and video input, double-checked all connections are secure, double-checked they are at the right port, and even replaced both the HDMI and USB-cables. There's nothing appearing on the OBS window. Have already set the PS5 to enable remote play. Documentation is quite poor so advice from experienced users is very welcome!
