Now play another MIDI file. Now play _another_ MIDI file. You will see that the "mute" icon on the tab has disappeared, and right-click-Mute-Tab no longer works. There is now no way to stop the sweet, sweet sound of 90s MIDI. Actual results: This has been confirmed by two others: https://news.ycombinator.com/item?id=17931759 Expected results: This shouldn't happen.
Hi Rich, Thanks for reporting this issue. Reproducible with the following specs: Version 64.0a1 Build ID: 20180912100128 Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv: 64.0) Gecko/20100101 Firefox/64.0
Alastor, didn't you work on this? Could you take a look? P2 for now but feel free to change as appropriate.
Priority: -- → P2
Sure, I will take a look, thanks.

Summary: Playing Multiple Audio Files via WebAssembly in Sequence Breaks "Mute Tab" → Calling resume on a running AudioContext results that the 'sound-playing' icon hides
When calling resume() on a running AudioContext, there is no need to discard current AudioChannelAgent and then create a new one.
