I'm trying to get a feel of what different devices are out there. As of Linux 4.17, the linux kernel is dropping the irda stack and device drivers. This is due to the fact that it is currently broken, and nobody is maintaining the code anymore. See: https://git.kernel.org/pub/scm/linux...56e9d599872a36

What this means that with the next release of pCP 5.0, we will moving to a 4.19 kernel, which will for sure cause issues with folks. There are 3 different types of devices out there
  1. GPIO connected IR receivers - will still work, but may require different configuration
  2. USB connected receivers emulating keyboards - These should still work as they do today.
  3. Other USB based IR receivers - These will no longer work

We have to move to newer kernels to support new audio devices, but that does mean that older hardware is going to have to change. You will of course be able to maintain your current configuration with pCP 4.1.0

Could we get some responses with they types of remotes you maybe using and the associated IR receiver?
