So I have found that when connected to my bluetooth headset, if I plug in wired headphones multimedia audio is rerouted from the headset to my headphones which saves power since system audio is not constantly being transmitted to the headset. I could always keep wired headphones plugged in all the time but this shows that it is possible for the multimedia and system audio to go through the phone speakers when the headset is connected. I just need to figure out how pulse audio routing is configured in terms of activities ie: multimedia vs system sounds vs calls when a bluetooth headset profile device is plugged in.
