How to use Logic I/O utility?

Hi all,

I would like to process audio from Logic X through an external hardware device, and I'm using a Universal Audio interface.

I followed this guidance in the Logic manual re. setting up the I/O Utility plug-in https://documentation.apple.com/en/logicstudio/effects/index.html#chapter=14%26s ection=3%26tasks=true although can someone please help with a couple of queries:

The Logic link above suggests clicking an Insert slot of an aux channel strip (being used as a bus send/return), and choose Utility > I/O. In the I/O window, choose both the Outputs and Inputs of your audio hardware (that your effects unit is connected to). Route the signals of any channel strips that you want to process to the bus (aux channel strip) chosen, and set appropriate Send levels. Adjust the Input or Output volume as required in the I/O window. Click the Latency Detection (Ping) button if you want to detect, and compensate for, any delay between the selected output and input. When you start playback, the signals of any channel strips routed to the aux channel (chosen in step 3) will be processed by the external effects unit.
However, the Logic guidance doesn't tell me how I can record the audio from the aux channel?! Can someone please help?
The audio from the aux channel sounds muffled and muted and there is no way to hear any subtle colouring from the hardware device. I understand there may be some latency colouring the sound but I thought the I/O plug-in took care of that? Can anyone suggest how I can hear a better representation of the processing on the aux channel?

Any suggestions welcome.

Kind Regards,

Mr Rock
