Ouch, dealing with regressions is always a bit sad :/ I would try the following: - Check if the audio.onerror event gives an error message, I see we don't really print that error out in the handler atm. Does the error message give a reason? - narrow down which Firefox version regressed. FF24 was good, FF27 was bad - which release regressed? How does latest nightly Firefox behave? - write a minimal Emscripten-based page that loads up and plays /sfx/fire.ogg, e.g. modify one of the built-in tests that play back audio, and post that compiled sample as a bug report to Emscripten, or if you confidently see that as a Firefox bug, then directly to Firefox bugzilla. - if Emscripten gets in the way, write a minimal handwritten JS page that loads up and plays /sfx/fire.ogg in a similar way that the Emscripten browser audio decoding in src/library_browser.js does. Perhaps that helps triage whether it's a data issue, an Emscripten audio loading issue, or a Firefox issue.
If all else fails, post a .zip file somewhere, and we can try to help out, Jukka 2014-02-16 15:59 GMT+02:00 Richard Quirk <[email protected]>: > I've upgraded Ubuntu 12.04 pulling in Firefox 27, and I noticed that sound > stopped working in my emscripten-compiled code.
