I have the USB drivers and audio CODECs set up now on the rig, but have not got FT8 working yet.
Years ago this would have been a trivial task, but with my "brain fog" this is like doing it blindfold: tasks that would have been easy in 2012 are now really hard, taxing and exhausting. I also thought a USB-C was the same as a micro-USB!! It isn't! Luckily I had one around.
I think for FT8 on the IC-705 I shall need a lead with isolation as the PC introduces noise I think.
