I’m using an audioinjector soundcard and output works fine, but I couldn’t get the input to work. Neither over MOD-UI nor over the “record audio” tool in the menu.

I’m using a raspi 4 and here are my zynthian versions:

Already checked the alsamixer, but it looks fine (compared it to [here](https://discourse.zynthian.org/t/official-rbpi-touchscreen-7/430/50))

Any hints on where to start fixing that? I already installed the drivers from the [github page](https://github.com/Audio-Injector/stereo-and-zero) and changed to RCA with their script.
