Pi Zero W with respeaker 2 mics

Help
1

Hi there,

i have running Rhasspy on my Synology as base Station on docker well. As Satellite 1 i use a Raspberry Pi 3 with a Matrix Voice Mic Array also without Problems. They communicate over an external MQTT Server.

For my second Satellite now i want to use an Pi Zero W with an ReSpeaker 2 Mic Hat. I startet from scratch how described in the Docs for the docker PiZero Installation 2 times with Raspi OS Buster lite and the ReSpeaker drivers without luck. I can record with “arecord -f cd test.wav” and play it with “aplay test.wav” succesfull on the ReSpeaker.

But in Rhasspy i get always errors. Mic and Speaker will not work.
Has anyone running with this Hardware succesfull?

Seems it just wants an integer index rather than string.

aplay -l

-Dplughw:0 or whatever index I usually use plughw over hw as it also adds automatic resampling channel mapping and reduces likelihood of error

Thanks for the hint. Finaly i get it yesterday evening working. Had to disable Audio in /boot/config.txt

Blockquote
dtparam=audio=off

Then these Settings worked in the Profile:

Blockquote
