Hi:

I encountered such issue when running command from official document to test the recording function:

hongfeij@raspberrypi:~ $ arecord -l
**** List of CAPTURE Hardware Devices ****
card 3: seeed2micvoicec [seeed-2mic-voicecard], device 0: fe203000.i2s-wm8960-hifi wm8960-hifi-0 [fe203000.i2s-wm8960-hifi wm8960-hifi-0]

Any clue about the reason and solution?

I run into exactly the same error, tried different forks (started with the one from the getting started at seeed-studio wiki, but that one is really old)

planned to create a small kiosk on rpi4B with wyoming satallite, waveshare display 4.3" DSI display, respeak 2mic and custom case

EDIT: fixed by

  1. uninstalling+reboot
  2. git checkout v6.6
  3. sudo ./install.sh

sudo rpi-update 1440b3e0b52075a9ec244216cddcf56099c28dfa to downgrade your kernel to 6.1.21 works for me. also I use the v6.6 branch. I don't know why

Yes, use the right branch.
