Yes, it looks like a defect in the microphones (but all 4 at once?), or a disconnection. I would try to wait for the next update while waiting for Living.Ai’s response.

Nomad also recommends writing to Living.Ai on Facebook, where he says they respond faster. I also wrote to them on FB a while ago, so we’ll see.
It’s hard to watch a little helpless robot.
