[AudioI] People Digest, Vol 9, Issue 1

[Tony Henrie]

Recently I had to reinstall my w audioinjector zero on my raspberrypi 4b and had problems. It turns out the rpi-update function in the installation script was the problem. @audioinjector, suggest you remove the rpi-update function from the script and stick with the current stable raspbian kernel. I had to roll back to a previous kernel to get it to work with other installed software.

@ Pratick Chaudri, the zero sound card should do what you are looking for, although it does not have stereo mic inputs. I have used it on a rpi 3b successfully. It performs well. Just be aware of the problem with the install script noted above.
