Bug Description
I have a working solution, somebody at https:/
I am using an Intel NUC with internal WiFi/Bluetooth and Seiki TV as a monitor, Ubuntu 14.04.2 64-bit with all recent updates and no particular customization but with blueman installeds. When I disconnect the Bluetooth headset, all audio stops working.
Reproduce-by:
* Reboot and log in.
* "System settings > Sound" shows "HDMI/DisplayPort built-in audio"
* "Test Sound > Test (Front Left)" works
* Power-on BT headset
* Open terminal
* Run "pulseaudio --kill"
* Wait... "Headset MW600" appears in "System settings > Sound"
* Select "Headset MW600"
* "Test Sound > Test (Mono)" works
* Power-off BT headset
* [optional, does not change result] run "pulseaudio --kill"
* Select "HDMI/DisplayPort built-in audio"
* "Test Sound > Test (Front Left)" causes "System settings" to gray out a long time (e.g., a minute)
* Sound is no longer working in any obvious way

wget -O alsa-info.sh http://
It brings up a first screen "This script visits the following ... to collect diagnostic information ..." I clicked <OK> and it apparently just hangs. I can Ctrl-C it.
If I run 'top', pulseaudio is about 1% of CPU on an ongoing basis. This seems high to me.
The instructions here say "what you think should happen instead", which is: I should be able to power-off the BT headset and audio should keep working.
I had installed blueman while chasing another problem. When I removed blueman (as in sudo apt-get remove blueman) the symptom above went away.
So for my needs, I'd say this is "fixed", but it also seems undesirable to have situations where things go bad with a hang. If somebody thinks this is worth chasing, I can re-install blueman and run tests people suggest to help diagnose the problem.

Tried utopic blueman (1.23-git201406 261335- deb-1ubuntu1) and no hang but still odd behaviours.
