Not sure what datatype S96000 is, but it doesn't like being added to a float.. Can you add some debugging to see what the actual value is being passed there?

self._buffer is <class 'bytes'> and data is <class 'numpy.ndarray'>

[NeonDaniel]

Looks like that's passing a list of lists instead of a list of floats?

Does this could be related to the ovos-microphone-plugin-sounddevice plugin?

I'd suspect so since I don't see it with the ALSA plugin. I think nparray has an asbytes function or something; this looks familiar...
