Separation of Stereo channel into two Mono Channel in A20

[vijayboboe]

We have done a Signage player based on Allwinner A20.  Our Team ported Android and tested the functionality. We are using the internal Codec powered by ALSA Driver.

We have HPL and HPR pin from the processor which is currently acting as stereo and the requirement is to convert two individual mono channel.

i.e  One Audio file has to play in HPL and Other Audio file has to play in HPR ( Two different songs )

Any one tried this before? If any one want to take up this as a task basis also it is fine.

Please share your thoughts.
