Hi Neil,

Many thanks for all your advice and answers.  Amusingly I've now learned
enough to discover that my headset is incorrectly wired - clearly I
wasn't paying enough attention when that conversation was going on
recently - but I think also enough to prepare a correct set of A3 state

Out of interest, what do you do for in-call audio?  (I hope I'm correct
in thinking that you have an A3.)  My current summary is:

- Using Pulseaudio successfully for the software routing, but...

- With Earpiece/Speaker there's echo (for the other person), and I
  haven't had success yet with any echo cancellation software.

- With Headset I'm now blocked until I can find a correctly wired one.
  (I have a 2.5mm/3.5mm adapter coming in the post.)

- With Bluetooth I haven't tried yet, but I think I have a Bluetooth
  headset lying around somewhere, so hope to try that shortly.
