No audio on duolingo.com



  • I'm learning languages on this site and none of their sample sounds will play. If you click on either of the two "play sound" icons while you're doing their lessons, nothing happens. It works on Chrome on Linux, as well as Vivaldi on Windows 7.
    This is the sort of page I mean:

    Clicking those sound buttons is supposed to play a sound sample but in Vivaldi for Linux it does nothing. Sound works on Vivaldi as I can play YouTube, Vimeo etc, not a problem. It's just Duolingo.

    Specs, Vivaldi for Linux 1.13.1008.40 64-bit, Linux Mint 18.3.

    Just tested and the audio works fine.
    Your issue might be related to proprietary audio and video on Linux. Check the Help Page. Let us know if it helps you.



  • Nope, I get "Reading state information... Done
    chromium-codecs-ffmpeg-extra is already the newest version (63.0.3239.84-0ubuntu0.16.04.1)."

    Already installed :(

    Just curious - doesn't Vivaldi share a code base with Chrome? As I said, Duolingo works fine with Chrome, so I'm just wondering why Vivaldi has issues?

    It's no biggie, I can use Chrome, but I'm trying to make Vivaldi my all-purpose browser.

    I don't have chromium-codecs-ffmpeg-extra instaled.

    AFAIK, Vivaldi is built on the top the Chrome code.

    It works flawless.

    Edit:
    Did you try those tests?

    I'm sure it does, and for other people too. But it doesn't work at all for me hence why I'm here asking for help. I've installed the widevine thing one of those pages suggest, but it's still the same. Neither mp3 nor mp4 will decode in the browser. All the other codecs on those pages work as intended.

    Do you mean the 2 tests above work? Perhaps your distro does not work with the codecs path.
    If you followed all the steps and still no audio, please Report a Bug



  • @mw2k Strange that I'm on Mint 18.2 (Cinnamon - 32bit) and all works fine. Maybe you missed some codecs. In this case I would like to suggest you this link where you can find some useful tricks ;) (the link already point to the Drivers and full multimedia support section)



  • I have the same problem with duolingo on a Windows 10 machine. On one computer it works without problems, on the other I don't hear anything on duolingo (while any other multimedia stuff works without problems). Interestingly enough, it used to work on this pc quite a while (with duolingo), and, without changing anything that I can remember, it stopped playing sounds there.
    On my second pc duolingo still works without problems.

    I do not really have an idea where the problem is...
