Description Chris Dumez 2020-12-16 10:06:50 PST
https://www.waveplayer.info/createmediaelementsource-test/ demo is flaky. Sometimes the page claims audio is playing but nothing can be heard on the speakers. Pausing / resuming the song seems to fix the issue. I suspect some kind of initialization race.
