Thanks for your help everyone
As the titles suggests, I have a bold that will insist on using the bluetooth device for output despite me not being connected to one or even close to one! This has happened twice now, initially I thought my handset was busted, but then realized that I had to switch the source to make my handset be the output device.
I should clarify, this happens (rarely) after having driven my wifes car which my BB is paired with.
The only way to fix it so far is by rebooting it
cheers!
