Hi! I'm a newbie on ALSA architecture. I would like to known if it would be possible to create a sound driver for a a PCM sound beeing acquired by the GPIO of a processor, like the ARM of a Beaglebone Black. Beaglebone has more than 32 bits of gpio so I intend to acquire the audio signal through a A/D CI (sigma delta) connected to a FPGA that would provide it to the Beaglebone Black in parallel form (PCM code), through the GPIO. Is that possible? Regards

Hi Raphael, Maybe you will have more success asking those questions and/or searching for answes on the ALSA Devel mailing list. Have you tried that? http://mailman.alsa-project.org/mailman/listinfo/alsa-devel Regards BGS
Hi Bruno, You are right. I will do it. Thank you. On Mon, Sep 29, 2014 at 2:29 PM, Bruno Guedes Souto <brunoguedes@gmail.com> wrote:
