I followed the instructions: https://github.com/matrix-io/matrix-creator-ir-test to set up the IR blaster/receiver on the matrix creator. It does work but I’m having a problem where after I send out an IR signal the sound on the raspberry pi wont work.
Has anyone any information on this?
I’ve tried factory resetting the pi, reinstalling the dependencies, resetting the pi audio configuration but nothing works!.
I read it could be an issue with pigpiod service but haven’t found any definite answers.
I’m using the analog output and the sound works perfectly before I used the IR blaster.
