Playing a sound involves the Thunkable app to issue a request to the operating system to play the sound using the driver. There is no guarantee that the request to start the sound will be done with a constant delay from request to playback, since those operations are asynchronous. It is like mailing a letter, you will know it will get there, you will know it will get there before a certain time, but that time can vary.
Hi there,
This is what I would recommend for blocks to make a sound play on a loop:
It will still be the case that there is a small gap between the sound ending and the new sound starting.
Have you tried getting a sound that is a single ‘click’ and playing it on repeat with a ‘wait seconds’ block between loops? (The amount of seconds can be less than 1 if expressed as a decimel). It could be easier to make an app that compensates for the delay that way.
