Windows 10, Brave Version 0.67.125 Chromium: 76.0.3809.100
This is a problem which previously occurred for me on Chrome - it’s now solved with Chrome. Also works with Edge, Firefox, Vivaldi etc.
Try to play this example web page, which uses an iframe to play back a recording : https://rootham.org/playlist/opus_020/listen_opus020_perf_mscore.html
What you should see is the music score for a string quartet, in sync with an embedded soundtrack from a video on YouTube. What I get in Brave is a rotating progress wheel - but the playback never starts and the visual score never appears.
“Allow all devices recognition” helps a bit, because now I actually get an error message:
“Autoplay was blocked on this page”
But the iframe on the web page I am trying to play already has the following parameters:
allow=“autoplay; fullscreen”
So I can’t do much more to improve my web page and its iframe. I think this is an error on the Brave side…
