We are using LSR TiWi-BLE module which uses Texas Instruments WL1271L chip
WE are trying to enable A2DP/Heaset via PCM interface, we followed below links and tried,

We have used below hci commands, and enabled the audio code in the BT module,
Now we are able to get the I2s clock output from the BT Module, but there is no I2S data coming out of the Device even after playback/record is initiated via bluetooth stack (here bluez).
So Is there any other HCI VS command, that needs to be called specifically in sequence before playback/record via PCM?
