Mcasp - Receiving bilingual LR input

Sushant Mayekar

Hi,

 We are working on mcasp of DM6467T with git linux v2.6.32 and dvsdk v3.10.

In our setup the sound device can provide bilingual LR channel with respect to the video received. So the L channel can contain Language 1 while R channel will carry Language 2. Is it possible in current Mcasp driver to separate L and R channel data into separate buffers by creating 2 sound devices one for L channel and other for R channel. Any other pointers are also awaited.

Thanks in advance

    Sushant,

    The simplest way for doing this would be to separate out the L and R data from the buffer at the application layer. The driver works on a single buffer and there is no provision for creating channel specific device nodes.
