As our customer wants a 5.2.9 kernel, I believe they will be using the buster-backports package for that (I'll confirm). If we want to enable the SOF driver and it's options by default are there any pointers about how I would do that? Is it just a case of pasting the CONFIG_ settings to this email thread or is something more subtle required (defconfig snippet etc)?

Got it - thanks. I managed to get the audio seemingly working in 5.2.9 with no driver changes needed (different firmware image) so I'm hoping (fingers crossed) I don't have to go this route but it's good to know it's available.

Thanks for all the help - I appreciate all the pointers.
