Just to report some progress with this.

I'm testing a Behringer UMC202 and a Focusrite 2i2 ( both stereo ADC and
DAC, up to 96k/24). They both work OK with Linux and RISC OS. Been making
test recordings using them. Quite impressed with the 2i2 in particular.

Fingers crossed I may also have a chance to try something else as well. But
the combination of the 2i2 and a Linux laptop look like a neat basis for a
portable audio recorder that delivers 'high rez' results.
