This is reported against an old version of Ubuntu and many things has
changed since then. Because of that we won't fix this issue however if
this behavior repeats on a modern version please fill a bug report
against it and we will take it from there.

** Changed in: bluez (Ubuntu)

  "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'.
