Audio error with newest Chrome update?
I was just about to relaunch an osweb study using JATOS/prolific and went to run a final check - only to find that the audio now cuts out after only a few correct responses (each followed by a correct! audio ping). The console error message is:
[Intervention] Blocked attempt to create a WebMediaPlayer as there are too many WebMediaPlayers already in existence. See crbug.com/1144736#c27
It works fine in other browsers but seems to be related to maximum number of audio output streams being reached? Which i guess explains why it happens partway through the experiment...but this is pretty over my head. Is there a way to set the opensesame audio player to only open a single stream or to close it after each time?
Thanks!
The game can be played here: https://onlinestudies.eva.mpg.de/publix/75/75/start?srid=221 (Instructions are in German but just touch the cross in the middle when its available and then try to click the yellow beads when they are there).

Also - there's a terminal work around that works for a single computer but not something I can ask recruited participants to do beforehand:
/Applications/'Google Chrome.app'/Contents/MacOS/'Google Chrome' --max-web-media-player-count=5000
Hi @popely ,
Thanks for reporting this. I can replicate this as well, and I'm going to look into it. For now, maybe you can use a simple
inline_javascriptto play the sample? Say that your sound file is calledmy_sound.oggand is in the file pool, then you can play it like this:This method of sound playback doesn't appear to suffer from the issue.
