After latest ESP updates rtttl.stop is not working

Well, it stops. But it hangs on the last tone, with a continous beeeeeeep. Only resetting the ESP32 will make it stop. Worked flawlessly until the last few days latest updates.
Now I have no idea how to make this stop, otger than stop using the function…

This is sent to the ESP32 through Automations calling service rtttl.stop.

Solved by telling it to play a mute tone instead.
