ALSA is the lowest level of the Linux sound stack. The alsa-utils package comes ready installed on the debian wheezy distribution I am using (2012-12-16-wheezy-raspbian. zip). It provides some useful commands: amixer, alsamixer, alsactl, aplay and speaker-test.

VS code works, however it saturates the rpi zero.
So not recommended for development.

Switching to terminal "ssh farnaz@192.168.0.104"

Setting up respeaker libs

git clone https://github.com/respeaker/seeed-voicecard.git
cd seeed-voicecard
sudo ./install.sh 2mic
sudo reboot

ALSA

aplay --list-devices

arecord --list-devices

check for 'card 1: seeed2micvoicec

arecord -f cd -Dhw:1 | aplay -Dhw:1

[Farnaz03]

I need to check what kernel version the respeaker 2mic needs. Need to make it compatible with the RPi OS

[Farnaz03]

Now trying sudo ./install_arm64.sh

[Farnaz03]

this resolve the error (for driver installation) - https://github.com/Sych-Tech/seeed-voicecard
