Hi everyone!
I’m trying to find if it is possible to build an audio DSP with an ARM board, and I would prefer a 8-channel output and at least stereo input (4-channel inputs would be better). I’ve read RK3399 datasheet and it says this SoC has two 8-channel and two stereo I2S buses. However it seems no RockPi provides multiple i2s buses I need: they either provide only one i2s bus with 8-channel output so there’s no input for me, or providing two i2s buses but none is “complete” so I don’t have enough output channels.
Any suggestions on it? Thanks!
