MCBSP-Audio(stereo)

Hi,

Iam running 16bit stereo format audio, only left channel data is transmitted. Right channel is null.

I have put the min and max channels to 2. How to configure mcbsp to stream the data in stereo mode?

I have another question, i want to run 24bit stereo format audio but mcbsp throws an error that it can only support 16LE. Do anyone know how to configure mcbsp to accept 24bit data as input format.

Thanks,

    You can find all that information on the TRM of the OMAP you are working with in the MCBSP section of the chapter Serial Communication Interface.

    24 data bits support will depend of the kernel you are using. I am not sure, but I think the driver in last version of android release also supports 32. For 24 bit support may imply that you need to modify the driver or do transfer as 32 bits and make the conversion at user space that is another option.
