Hi , sorry for my bad english, I hope you can understand me
I have a rpi3 and matrix voice addon. I use on rpi 2019-04-08-raspbian-stretch-lite.img, after first boot I make sudo apt update and upgrade and add the repository and key.
sudo apt install matrixio-kernel-modules shows these error
cleaning build area…
make -j4 KERNELRELEASE=4.19.42-v7+ -C /lib/modules/4.19.42-v7+/build M=/var/lib/dkms/matrixio/0.1/build…(bad exit status: 2)
Error! Bad return status for module build on kernel: 4.19.42-v7+ (armv7l)

The latest Raspbian image actually uses an updated Linux kernel that has some breaking changes with our MATRIX kernel modules. We are working on the fix now & will update soon.
Theoretically, if you use the old Raspbian Stretch image with Linux kernel version 4.14, our kernel modules should work with it. I will test this & confirm this weekend so it can be a temporary workaround!
