5.1 surround not working in Chrome

[King Mustard]

I downloaded this YouTube video in both MKV and MP4 formats using 4K Video Downloader and MediaInfo confirms both contain 6-channel AAC LC audio.

The downloaded files, when played in PotPlayer v1.7.21126 (released in February 2020), definitely contain separate channels. It worked perfectly as intended.

However, when I play the video in YouTube (highest quality available; 1080p) in Google Chrome v80 (released in February 2020), I only get stereo (or fake surround - the rear channels play primarily through the front speakers).

Same issue in Internet Explorer 11.719.18362 and Microsoft Edge 44.18362.449.

Windows is set up correctly as, as I said, PotPlayer played the individual channels in the downloaded video file fine and all games work in surround as they should.

Any ideas?

Last time I looked into this (about a year ago trying to get Amazon Prime in 5.1), everything I found said that all web browsers only support up to stereo and none of the web standards could support 5.1. End result is Netflix on my Windows 10 plays in 5.1 through its dedicated app but for Amazon Prime I'd need to get an Android box or a FireTV stick!

Things probably have moved on in the past year, but it could just be that browsers still can't do surround.

Also how are you sending audio out? Over analogue RCA or optical/coaxial/hdmi?

As when I playback 6ch aac I only get 2 channel from the Av amp, as aac isn't a official avr decoder. I'm Sending over optical/coaxial
