Hi,
However, the alarm still plays the old sound file and not the one configured at in the Modules.
You should ask the module author for the solution. Possibly write to him on GitHub.
By the way, did you restart the Server service?
Eg. alarm should play when channel value is 1 but should but play if it goes to 0.
Create an extra input channel of the calculated type and revert the value:
Val(101) > 0 ? 0 : 1
101 is the number of the source input channel
