Audio files online

I am trying to run my experiment online. There should be some audio feedback after each trial. When I initally tried to run it using wav it said that wav files are not supported so following on from some advice I read on this forum I changed the sound files to mp3 files but those do not work either online and i get this notification at the point where the sound in the experiment should be heard:

Any advice on how to make the sound component work online would be appreciated.Thank you

I insterted the sound in the following way:



Hi There,

You will need to add the mp3 files to the additional resources section in builder.

Experiment settings (cog icon) > online > additional resources.

Thanks,
