		uint32_t	leftRecordChannel,
		uint32_t	rightRecordChannel
	)

Parameters

handle	codec handle.
leftRecordChannel	audio codec record channel, reference _codec_record_channel, can be a value or combine value of member in _codec_record_channel.
rightRecordChannel	audio codec record channel, reference _codec_record_channel, can be a value combine of member in _codec_record_channel.

Returns: kStatus_Success is success, else configure failed.

status_t HAL_CODEC_SetPlay	(	void *	handle,
		uint32_t	playSource
	)

Parameters

status_t HAL_CODEC_ModuleControl	(	void *	handle,
		uint32_t	cmd,
		uint32_t	data
	)

This function is used for codec module control, support switch digital interface cmd, can be expand to support codec module specific feature

Parameters

handle	codec handle.
cmd	module control cmd, reference _codec_module_ctrl_cmd.
data	value to write, when cmd is kCODEC_ModuleRecordSourceChannel, the data should be a value combine of channel and source, please reference macro CODEC_MODULE_RECORD_SOURCE_CHANNEL(source, LP, LN, RP, RN), reference codec specific driver for detail configurations.

Returns: kStatus_Success is success, else configure failed.
