There is some progress, I installed a different Pi (Pi2B) with a different DAC (Boss) and the latest image; right now I’m not seeing the errors starting irexec. However, the signals are still not being processed as it seems. When I list the processes (pstree) both lircd and irexec are showing now, so I think the other image might have been disrupted.

Dmesg, the service and the journal don’t seem to be showing errors regarding lirc.

What has not changed?
- controls are not being propagated to volumio, I’m not seeing anything when I tail the journal
- irw still gives me nothing as well, I think this should rule out a problem in Volumio?
I’m using an Apple A1156 remote and a TSOP38238 receiver wired to the GPIO27 pin on the Boss DAC @3.3V and mode2 shows activity when I press buttons.
Any tips for this tinkerer? I really don’t know how to debug/check the irexec, but if someone can tell me how, I’ll definitely give it a try.
I’m so embarrassed now, that was it! Everything works great now.
