CORS request will not work in Chrome

Question

I know this question has been asked before, I have read/tried them all. I am needing to do createMediaElementSource on mp3 files stored on a different domain for visualizations. What I have works well in Safari and Edge but not in Chrome (dunno about FireFox). The issue is if I create the element from a cross-origin source using:

var audioSrc = ctx.createMediaElementSource(cfg.audio);

...where cfg.audio is cross-domain, Chrome gives me:

MediaElementAudioSource outputs zeroes due to CORS access restrictions

But I have (among other things) in my .htaccess:

Header set Access-Control-Allow-Origin: "http://the-correct-domain.com"

I have checked the header at the webconfs.com site and am getting:

HTTP/1.1 200 OK =>

Connection => close
Content-Type => audio/mpeg

(I started with a simple Access-Control-Allow-Origin: "*" and have added crap from that point). The script works just fine using a local mp3 file, and I tried adding PHP voodoo from HERE to no avail. Where have I gone wrong?

Got it at long last, thanks to this post. I changed the script from audio.crossOrigin = 'Anonymous' to audio.crossOrigin = 'use-credentials' and all is well. You're my hero pdg137!
