Hi @715yeung , thanks for reporting this!

I think the immediate problem is that this error message isn't very good:

Unexpected '' at the top level

There appears to be some kind of unexpected character at the beginning of the file you're attempting to play, however, the error message doesn't really say what character it is. I think it's some kind of character that doesn't have a visual representation.

I would have guessed that it's a control character of some kind, but we do check for control characters and print the code point, and that's not what's happening here. So, it must be some other kind of unexpected character. Maybe a Unicode character of some kind?

If you could attach the file you're trying to play to this issue, that would be helpful to me in debugging this issue.
