RubikPi 3 connects an ES8316 codec to primary MI2S for headset playback and capture, and an LT9611 bridge to quaternary MI2S for HDMI audio. Add per-DAI data for the primary playback and capture links. Configure the codecs for I2S with normal clock polarity and as bit and frame clock consumers. Program the primary MI2S BCLK, configure the ES8316 for its fixed 19.2 MHz MCLK and enable component jack detection on the playback link. The HDMI link inherits the card-wide I2S format but does not request codec sysclk programming because the LT9611 codec DAI does not implement set_sysclk(). Select this configuration through the RubikPi 3 sound-card compatible.
