When streaming bluetooth audio, the sound is choppy due to the fact that the default baud rate of the HCI interface is too slow to handle 16-bit stereo at 48KHz.
The Bluetooth chip is capable of up to 4M baud on the serial port, so this patch sets the max-speed to 4000000 in order to properly stream audio over the Bluetooth.
