Bug Description
I have a 2.1 speaker system and a Logitech bluetooth adapter for them that connects to my Asus UL50AG notebook for sound.
In Sound Settings, I then have 2 entries: Built-in Audio Card and Logitech Adapter.
The problem is that when I connect/reconnect to the bluetooth adapter, the sound volume knob is not bound to the Logitech Adapter. Instead, in Sound Settings, the Built-in Audio Card is selected instead of the Logitech Adapter. And when I use the multimedia keys on my notebook (Volume Up, Down, Mute), they have effect on the sound coming out of the notebook, not the external speakers.
The expected result would be that, when I connect/reconnect the bluetooth adapter, the volume multimedia keys should bound to the new bluetooth setup, not the internal audio.

Solutions:
By editing the /etc/pulse/ default. pa we can load the pulseaudio module module- switch- on-connect to autoconnect to an audio sink as soon as it is presented to the pulseaudio sound server. We need to insert the following line
load-module module- switch- on-connect
-----
or
-----
stream2ip
----
or
----
bt-autoconnect
But still, right after connecting, the volume returned to the adapter is very loud at first; after I move the volume slider even a bit from its current location, then the volume corrects itself suddenly to it's ACTUAL position. This is so messed up in so many ways I can't even try to imagine the back-end of this all wreckage.... Just freaking do something... it's quite embarrassing.
