Pi-top speaker input from proto board?

Is there a way to input sound to the pi-top speaker directly from a pi-top proto board?

Reason i'm asking: I want to play around with electronic sound generation (like a MOS 8580 chip). I'm pretty sure i can record the audio via an USB audio card and pipe it through HDMI, but that's a waste of processor resources.

My idea would have been to use the speaker directly. Is that even possible?

Hi Rene,

I believe the Pi-Top speaker (although mine hasn't arrived yet) uses the SPDIF signal (from HDMI) that is fed via pin 6 of the Pi-Top hub connector.

Not sure if that helps you though, probably tricky to feed your audio source in there.
