Multiple 8xout on a single Raspberry

Hi RaspiAudio team and community,

I’m working on a Raspberry Pi audio project and I’m considering using two RaspiAudio 8xOut boards.

Is it possible to stack two 8xOut sound cards on the same Raspberry Pi and have them both work correctly?

If so, is there a way to aggregate them into a single audio device, for example exposing 16 output channels to the system (via ALSA, JACK, or similar), rather than having them as two separate devices?

My goal is to use all outputs in a synchronized way as one multichannel interface.

Thanks a lot!

hi, no it’s not possible because on the Pi5 you have 4 I2s buses each stereo resulting in a max of 8 channels outputs. Adding 2 boards of 8xout will only give you the same channels duplicated.
