Cubase ASIO audio issues

Hi There,
I’m struggling with an audio issue (and also with how to navigate this forum!) so apols if this is the wrong place to post.

I’m not getting any audio playback from an audio (vocals) track.

My setup is:
PC connected via USB 2 to a Yamaha MG10xu with a mic in to that. I’ve got headphones plugged in to the Yamaha’s stereo/phones jack.

I think I’ve set up all the audio / ASIO outputs and inputs correctly (have currently got the steinberg yamaha USB driver selected).

I switched the driver to the generic low latency one and this enabled me to hear the audio playback (through computer speakers, not headphones plugged in to the yamaha MG), but then didn’t let me record (wouldn’t get an input from the MG)

Any help would be greatly appreciated. I am not super technical so simple wording would be super.

Thanks
