no sound (Linux mint 22.1)

xfce4-timer-plugin 1.7.2 (On linux Mint 19 without problems.) No audio output with the command "play" Dependency - sox - is not installed. Installing sox fixes the problem.

This plugin doesn't have an option to play a sound as far as I know. Didn't you set up a custom command to do this, as indicated in #10 (comment 17590)? In that case, it's up to you to install the required dependencies.
