Hi David, Raymond, thanks for your follow up. Here is more pertinent
information:

Changing from "Multichannel output" to "Multichannel input" on the
Output tab in gnome sound settings makes the UA-101 output device
disappear completely and permenantly and it does not appear in the Input
tab. The only way to restore it is remove pulse files from home
directory or use pavucontrol.

Checking pavucontrol in this instance shows that the profile for the
card has actually been set to "Off" rather than "Multichannel Input".

Changing the profile in pavucontrol for the UA-101 to "Multichannel
Output" shows a 10 channel output device, set up with 10 channel output
device (with 8x 7.1 surround channels and 2 auxs) in the Output Devices
tab of pavucontrol and a 10 channel input device called "Monitor of
EDIROL UA-101 Multichannel" set up with the same channel names as the
outputs in the Input Devices tab.

Changing the configuration profile to "Multichannel Input" and the
UA-101 device disappears completely and there are no devices
representing the UA-101 in either the Output or Input tabs of
pavucontrol.

Using Jack2 and QJackCtl works, creating 12 inputs and 10 outputs.

Strangely, Jack recognises 12 input channels wheres
pulseaudio/pavucontrol only recognises 10.

Looking at the circuit diagram on the top of the UA-101 shows that it
has 10 inputs (two of which are optical inputs) and 10 outputs (two of
which are optical outputs) as well as 2 monitor output channels - this
determines that there are in reality 10 inputs and 12 outputs....... :/
confused :S

The circuit diagram can be seen here:
