Hi,
I want to transmit voice data through CSR modules so
that I can talk with others using speaker and
microphone.And I connecte a C145483 Codec throught PCM
interface .But unfortunately,CSR module doesn't send 
the PCM clock and sync,so the Codec doesn't work.And
now, I know that when the CSR module is set as a PCM
master it will send the PCM clock. However ,I don't
know how to do that. I can change the PCM mapping
using pskey just like this: 
$ pskey -i hci0 mapsco 0
$ hciconfig hci0 revision
hci0:   Type: UART
        BD Address: 4A:49:4E:00:15:2F ACL MTU: 384:4
SCO                          MTU: 64:8
        Build 705
        Chip version: BlueCore02-External
        Max key size: 56 bit
        SCO mapping:  HCI
So, what can I do?

Thanks in advance!
