It is certainly causing me a lot of agrievation!

I am writing to disk (or not) so why is it concerned about opening
ALSA access?  This is seriously impinging on my work now as I cannot
test anything

never seen this before. It should not even have tried opening the device.

you can try adding -+rtaudio=null to avoid loading alsa
