Alexa ReSpeaker 6-Mic Circular Array kit for Raspberry Pi

Post by p.decadenet » Sat Dec 29, 2018 11:57 pm

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

Pierre
