The IR remote first volumio toggle command doesn't work

Hello friends.
I’m using Volumio version 4.119 running on a Raspberry Pi 4 and an Audiophonics DAC board ES9038. The IR remote control plugin has been installed, and the necessary configuration files for LIRC have been created. Everything works without problems except for the command for play/stop (toggle) via IR, and that only when the Pi is turned on, and Volumio is finishing starting up. After that, play/stop, it works until Pi is turned off and on again. To clarify, when pressing the PLAY key, either nothing happens, or PLAY starts for a short time and then stops again. I should mention that I use the same IR remote on Pi 3B+ and Volumio version 2.917, and everything works without problems. Does anyone have a similar experience or know what could be the reason?
Thanks in advance.
