"A" way (not ideal! ;-) to resolve the problem is to simply remove the
bluez-alsa package:
$ sudo apt-get remove blue-alsa
Notes:
- I have no bluetooth audio devices within range or enabled.
- I have no ~/.asoundrc so unclear why I'm getting all the alsa cruft.
Attached is the output of 'sudo hcidump -XYt'.
