Hi:

how to enable pcm ?

i add HCI_VS_Write_CODEC_Config in bts,

but i can not measure  the pcm clock(PCM_AUD_CLK) with an oscilloscope. 

After connecting the Bluetooth chip with the phone, play the music. also can not measure PCM_AUD_DIN,PCM_AUD_DOUT .

Send_HCI_VS_Write_CODEC_Config 0xFD06, 0x0200, 0x00, 0x00001f40, 0x0001, 0x00, 0x00, 0x00, 0x0010, 0x0001, 0x00, 0x0010, 0x0001, 0x01, 0x00, 0x0010, 0x0011, 0x00, 0x0010, 0x0011, 0x01, 0x00
