Henrik LangerWe're looking for a low cost SBC with a more powerful CPU and multichannel I2S port (e.g. Freescale i.MX series or TI AM5728) to achieve a lower latency and implement more complex audio effects or synthesizers. The Allwinner SoCs seem to be a good choice, too. Unfortunately the ASoC platform driver for the Enhanced Serial Audio Interface (ESAI) of Allwinner SoCs only support 2 audio channels. We appreciate any suggestions.
