No voice go passing throught my microphone

[sollekram]

I tried this module https://github.com/eouia/MMM-Assistant (i install only google assistant note i didnt use the speech cloud cause i dont want, unless its important)
i start the magic mirror and everything is fine, the icon of microphone appears, but when im talking and say magic-mirror or snowboy or ok google, it appears that nothing particularly happens.

what may i’ve done wrong ?
i mean it starts with no errors, i got it step by step, but no voice going through, also arecord works when i doing it on terminal, it record perfectly my voice.

fyi: I use a ps3 camera, should i register it somewhere on magicmirror or everything fine as it is?
