I read, that using MYNDberry, audio via USB-C or AUX is not possible anymore. Are there any plans or ideas (how) to change this? I’d love to try the extended capabilities and keeping audio via USB-C/AUX available. Probably is like having the cake and eat it…? 
The problem is that in stock configuration, USB soundcard and Aux-in/ADC are handled by the Bluetooth SOC. Since we have to remove that we lose these functions. We thought about adding a PCM1808 DAC to the MYNDberry PCB, however Moode currently doesn’t support any playback from I2S in, despite RasPi offering that function. Same problem with USB-Soundcard.
To enable these functions, we’d need to have at least two independent sources playing back I2S audio with independent volumes as well and no way to elegantly switch over.
Basically, you’d need to add a USB Soundcard IC, a ADC and a small DSP that takes care of mixing those and RasPi audio. Which is possible but at this point sadly out of scope.
