I am creating Audio at runtime and then setting the source.

let snd = new Audio();
snd.src = "file.mp3";

It works in Edge every time. Occasionally, it fails in Chrome, especially when I am debugging. It only really fails on the first time I start debugging in a session, almost always working every time after. Once it works, it repeatedly works for that session.

Note the error is MEDIA_ERR_SRC_NOT_SUPPORTED, which I know is not true, because it works, typically, the second time.

From what I have read here on Stackoverflow, there may be a known problem with this for large sound files (which this is in my case).

So my solution is, refresh the page when an onerror is fired:

snd.onerror = _ => window.location.refresh(true);

Note the true.

When you do this true means you are refreshing from the server. false means you are refreshing from the cache.

QUESTION: Considering my problem, which should I be doing, true or false?

Because of the low fail-rate, this is a real pain to debug, so any advice will be much appreciated.
