    Intel Edison - I2S Audio Setup


      The latest Edison firmware update adds the I2S support. And so I played with it and got my Edison board working with Wolfson WM8731 codec (TI TLV320AIC23B seems to be compatible).

      I tired two different options:

      1. Writing an ASoC machine driver. I finally got it working last Saturday, and I will describe it in details later. I just mention that it requires a kernel modification.

      2. Using the default "dummy" output, and configuring the codec using a series of i2cset commands. I described the process in my blog here: Intel Edison - Simple I2S Audio Setup - Malinov Family Web Presence
