>Description:
        Configuring and using a bluetooth headset, I don't get sound
        either way (recording or playing).  Following section 20.7.1 of
        the NetBSD Guide, everything is fine up until the bthset(1)
        command is run.  While I hear beeps in the device, that command
        never returns (it can be ^C'd, though), and subsequent uses of
        audioplay and audiorecord don't get any packet in or out of the
        audio device.  I do hear additional beeps when I ^C e.g.
        audioplay and it quits.
>How-To-Repeat:
        According to the MAC address, this Bluetooth device seems to be
        from Perfect Tech (00:12:c8).
>Fix:
        Unknown.
