Headset used Iqua BHS-611.

How to reproduce this error:

1.    sudo hciconfig device up
2.    hcitool scan
3.    sudo bluez-simple-agent hci0 <mac>
4.    sudo bluez-test-device trusted <mac> yes
5.    pulseaudio -k; sleep 4; pulseaudio -vv;
6.    pactl load-module module-alsa-sink device="btheadset"
7.    pactl load-module module-alsa-source device="btheadset"
8.    aplay -D btheadset -f S16_LE wave.wav
         Works
9.    arecord -D btheadset -f S16_LE wave2.wav
         Recording WAVE 'wave2.wav' : Signed 16 bit Little Endian, Rate 
8000 Hz, Mono
         Final wave2.wav is always 2.092 B in size and contains only a 
wave header and zeroes.
10.    parec
         Shows no output.


Please use as a bug report or - better - show a solution.

PS:

   .asoundrc:

    pcm.bt {
            type plug
            slave {
                    pcm "bt_hw"
            }
    }

    pcm.bt_hw {
            type bluetooth
            device 00:1A:7D:11:C0:66
            profile "auto"
    }

There are dedicated modules for bluetooth such as
module-bluetooth-discover which will do the device detection
automatically for you, and if you need you can also load manually via
module-bluetooth-device.

This probably doesn't work anymore, if ever worked, PA has native
modules for Bluetooth for quite long time, please use those instead of
using alsa.
