I tried mailing on the bluez-users list :but no luck (hence attempting it here)
2)
I am using
   Headset Model Number: motorola HT820

Contents of .asoundrc is as below:
 cat ~/.asoundrc
pcm.bluetooth {
 type bluetooth
 device 00:07:A4:B7:51:8D
}

using bluez4.6 & kernel 2.6.27.rc6

when i use
$aplay -D bluetooth -f S16_LE shutdown1.wav
Playing WAVE 'shutdown1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stere
I am able to hear it in my HT820

where as when i do
1)
arecord -D bluetooth -r 44100 -f S16_LE new.wav
Recording WAVE 'new.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
I kept the above command running for few seconds & then pressed ctrl-c.
there is new.wav file created of size just 44 bytes & when i try aplay
on this nothing is heard( i think this is due to no recording on this
file).
2) I get the following error For
 I use the below command to hear what i have said in the microphone.!
$ arecord -Dplug:bluetooth -f S16_LE | aplay -D bluetooth -f S16_LE
