I am building a mobile friendly website. there I need to embed a PowerPoint presentation with an automatically playing audio file. I used following iframe code generated by PowerPoint itself & one suggestion from Stack overflow
<iframe src="https://onedrive.live.com/embed?resid=xxxxxxxxxxxxxxxxx;authkey=xxxxxxxxx-egw&em=2&wdAr=1.7777777777777777" width="610px" height="367px" frameborder="0">This is an embedded <a target="_blank" href="https://office.com">Microsoft Office</a> presentation, powered by <a target="_blank" href="https://office.com/webapps">Office</a>.</iframe>
this work properly on chrome & edge. but when i try to open it with my mobile phone (safari for iPhone) audios do not play automatically. i have to press the button. is there any other way i can achieve this goal?
currently PowerPoint web embed do not support audio auto play. use a SCORM authorizing tool to convert ppt files in to a HTML package. SCORM Software Tools
