I’ve been trying to record audio with the Matrix Voice board.
I followed the required steps to install the Matrix HAL and the MatrixIO Kernel Modules for the Raspberry Pi 3B+
Every time I run the command
arecord -f S16_LE -Dplug:all_channels -c 8 all.wav
I get a bunch of errors (screenshot attached)
I do not know what is wrong, I tried with fresh Raspberry Pi OS (Buster) images and I’m still getting the same errors.
I would like to know how I can get this running.
Things I’ve done to make sure the board works:
- Running the everloop examples
- Checking the FPGA firmware
