I've noticed an annoying bug when using a bluetooth headset. After initiating a call using the bluetooth voice dial, all the audio on the phone stops working. I'm unable to hear the person on the other end and then after turning off bluetooth the phones audio (notifications, music, etc.) stops working, requiring a reboot. The only way to avoid this is to make calls directly from the phone, which isn't the safest thing to do while on the road. I've come across a tread while looking for a solution that mentions a fix over at xda, but i've been unable to find it. Any help would be greatly appreciated.
