Alexa ReSpeaker 6-Mic Circular Array kit for Raspberry Pi

I was recently bought a ReSpeaker 6-Mic Circular Array kit for Raspberry Pi.



The install of drivers completed successfully, and I have managed to get trespeaker_4mic_array.py working so the connection to the board seems to be working, however I try to start alexa-tap it returns me an error :



alexa-tap

press ENTER to talk

arecord: set_params:1299: Sample format non available

Available formats:

  • S32_LE



    Do you have an idea



    Best regards
