the audio path is something that you should realy take care and look at the 
possibiliites provided by your hardware.
- does your device can send/Receive audio through HCI ? and if yes, I 
really thing you need to send vendor specific command to configure it (the 
device has also the possibilities to use a analogic path, or a IOM one if 
they are available)
- does your device support 16 bit PCM steaming ? If not, you should use 
another setting for "hciconfig hci0 voice 0x0040" and hack hstest to accept 
ulaw/alaw instead of PCM (if it's not already done)
