[udgish23]

Hi nice tutorial I have application running on the node js and alsa mixer my default mic is seed 4 mic hat and its current device name (location) plughw:1,0 now I want to change to echo cancellation hw as my mic .

I tied the config.sound file copy then no sound output coming.

I have attached the my default setting image of alsa.

How to solve the noise?

Any other possible error or advice also recommended.

Thanks in advance

You can use the alsa plugin fifo.

with the asound.conf, the device name is eco, just replace plughw:1,0 with eco.
