Hi Kevin, Are you sure the api your using is compatible with gtkwebkit2 (the web engine sugar uses)? Try installing 'epiphany' (aka. Web) outside osbuild. Epiphany also uses gtkwebkit2 - so if it works in Epiphany it is a bug is sugar or osbuild. (I wouldn't be surprised if it doesn't work - gtkwebkit2 is not as good as firefox or chrome) Sam <div class="gmail_quote">On Jun 23, 2014 7:53 PM, "Kevin Kreuzer" <<a href="mailto:kevin.kreuzer90@icloud.com">kevin.kreuzer90@icloud.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello I am developing a Sugar Web Activity. I have installed osbuild on an Linux Fedora to have a full Sugar environment. In my application I want to include sounds. If I visit a website with the browser in Sugar I am able to play sounds. I have already written the code for the sound. This code looks like this: var backgroundmusic = new Audio(""); document.body.appendChild(backgroundmusic); backgroundmusic.src = „blabla.ogg" backgroundmusic.play(); Everything works perfectly fine if I start my application with Sugarizer in a Web Browser by double clicking on the index.html. But if I run my application on Sugar it doesn’t work. If have tried now for a few days and I am always getting the same result. Am I missing any configuration or is there something wrong with my installation?
