Possibly related to Issue #71 Until V4 it was working without any issues but after updating to V4 the program broke. I have tried reinstalling it several times both from the AUR and directly from github and it fails the same way every time. Installing V3 from git creates a functioning configuration but upgradig to V4.1.2 and running the script to migrate the config breaks the program and subsequent attempts to reconfigure the program fails.

Sorry for not updating, had a very busy few weeks. I tried v4.1.4 and configuration is now working, thank you so much! 😃

Ok, things become complicated to explains ^^ The problem is that I cannot find a fix if I don’t have precisely the state of the two mentioned files before and after update in a “regular” situation.

1. Uninstall the v3 and v4 (no more files in /usr/lib/linux-enable-ir-emitter/ and /etc/linux-enable-ir-emitter/ and /etc/linux-enable-ir-emitter.yaml)
2. Shut down your computer
3. remove the AC adaptater
4. boot, install the v3 and configure the emitter
5. reboot, is everythings working ?
6. install the v4
7. past the content of /etc/linux-enable-ir-emitter/video2 and linux-enable-ir-emitter boot status

I won’t have time to try debugging today. So I think it’s better for you to go back to v3. And probably tomorrow I’ll install a VM with Arch to do some tests …
