If my understanding was correct, Lars-Peter's presentation at ELCE was using idea of "Bridge". This idea is not exist in current ALSA SoC, but current DAI can be updated to it ? Then, current notion can be udated also? I'm not 100% understanding how to update, how to use, etc, but my Image is... sink source +---+ +---+ |DAI|--->|DAI| +---+ +---+ ----> +------------+ | Bridge | +------------+ Thank you for your help !!
