No audio on one YouTube video

There’s a YouTube video which, when I play it, I get no audio output.

Other YouTube videos play just fine. The same video, played using the Kodi YouTube add-on on another device, plays normally, with sound.

I’ve tried updating to the latest alpha version of the YouTube add-on and that didn’t help.

Can’t reproduce. Audio of the linked video works with the latest stable version (6.8.9). Try going back to that and see if it persists.

I got the problem with the latest stable version - that’s why I tried upgrading to the alpha, to see if it would help. (It didn’t).

That’s strange. Did you get the “YouTube error. Check the log for more information” message when trying to play music videos like this one with 6.8.9 as well? Originally the 6.8.10dev was released to fix that bug. I haven’t read about people who could play videos but don’t get audio.

I think the fault lies in lines 8662–8673.

Looks like the addon can’t find its API key. You did go though the process of creating your own API key and telling it to the addon, right? Were you logged into a YouTube account with it? Make sure the addon still has the API key.

Yes, and yes. I certainly still have access to my subscription settings, now, so I think I’m still logged in correctly.

I found one of the lines from your log in this post but no reply to fix the issue. I’m out of ideas except for uninstalling it, removing everything else it touched, and reinstalling. Sorry, mate.
