Problem with audio formats (m4a)

[Aurion-a]

Hi,

So the User Guide says:
"Audio tracks to be used in the game:
Data Format - OGG, M4A"

I spend a bunch of time figuring out how to convert my audio files to m4a, and when I finally managed to do it, I tried to load the .m4a file with a "play music" command, and this error appeared:

"An error occurred while decoding the audio data. see details below.
DataCloneError: cannot decode detached ArrayBuffer"

I tried converting the file to mp3, and it worked perfectly. So I guess mp3 is also supported?

Can I import everything in mp3 instead?
