When I tried to play a WAV file on chrome it said decoding failed. I tried to rename the file to an mp3 file but it said the same thing
Renaming will not help since it may be an absent codec that is the problem. Different audio formats use different codecs, so we must use a converter to properly transform the format.
You could look into how to install the WAV codec (if that is possible) on your machine so that it can be decoded. Other than that, perhaps look for an online resource that can convert the file to
.mp3 and let you download the new file.
One more question. should WAV files be able to play on chromebook
