Hi, Need an input from you guys please. Is there a possibility to play out an audio using aplay or any alsa tools without the presence of the codec driver In our target platform, we have the SoC's I2S platform driver working, and a dummy codec driver is registered The actual codec chip sits on a external board and connected to the main SoC via I2S and I2C lines. And that codec chip is configured via a middleware package(not alsa) So we do not have a codec driver at the kernel space, we have just provided a plain I2C interface driver for the middleware package. so that it can send I2C commands directly to the audio codec chip. Based on the requirement have to give the control interface of the codec chip to the middleware package In this case is there a possibility to play out an audio file using alsa tools(eg. aplay) Just a raw PCM format should be enough. Thanks, Babu
