How to setup AM335 PCM clock/Fsync & Volume Up/Down

HI,

Sorry for my English.

I used the ti-processor-sdk-linux-am335x-evm-01.00.00.03 +  TI Bluetooth Linux Add-On package on AM335 EVM GP

We test the BT  with HandFree profile and then it's works well.

I have few questions as below,

1. when the HFP enabled , the BT is slave and CPU(host) is master , the CPU send the PCM clock 1.6Mhz and Fsync 16K to the BT , I want to adjust it  ,but idont know how to do ? like PCM 512K & Fsync 8K .

2. As Item 1 , if I want to change the role that is BT as master and CPU as slave how to change it ?

3. When HFP enabled , I found the voice is too low from the audio jack , so how to increase the volume from the PCM on the am335
