Thanks for the reply

SO I have hci_usb compiled in my kernel...
These are things I d= id now...
[root@localhost Pramod]# mv /etc/modules.conf /etc/modules.con= f_old
copied these lines to /etc/modprobe.conf
alias net-pf-31 bluez&= nbsp; ------> changed to -----> alias net-pf-31 bluetooth
al= ias bt-proto-0 l2cap
alias bt-proto-2 sco
alias bt-proto-3 rfcomm
= Added "options =0Ahci_usb =0Aforce_scofix=3D1" to /etc/modprobe.conf = file...
Now I rebooted ..
When I restarted my hcid(with sdpd, audi-se= rvice autostart) I found some things that I never seen
before in /var/l= og/messages these are
/***This log appeared for first time*****/
Feb = 13 09:48:40 localhost audio[2473]: Loading device 00:0F:DE:B1:02:42 (headse= t )
Feb 13 09:48:40 localhost audio[2473]: Setting 00:0F:DE:B1:02:42 as = default device

Then I did
[Pramod@localhost ~]$ arecord -D bluet= ooth -f S16_LE test.raw

both ACL and SCO were established
I was = able to record sound from headset...
But when I tried
[Pramod@localho= st ~]$ aplay -D bluetooth -f S16_LE test.raw
Playing raw data 'test.raw'= : Signed 16 bit Little Endian, Rate 8000 Hz, Mono

No sound was list= ened on headset
