What’s in you openhab.log? events.log is only useful to see the state changes if you’re items. Errors and the output of the exec commend will be in openhab.log.

Bear in mind that doesn’t do what you probably expect.
A command is issued to SwitchPlaySound, but the rule does not stop and wait for it to be actioned before moving on to logging. You’ll most likely log the state before any exec action happens.
