I cannot reproduce this with Safari 9.0.3 (shipping WebKit). I only get an exception in console:

InvalidStateError: DOM Exception 11: An attempt was made to use an object that is not, or is no longer, usable.
createMediaElementSource safari-issue.html:92
handleCanplay safari-issue.html:92

Try this

1. Make sure the WebInspector is NOT open (nor any other JavaScript tools)

2. Go to http://greggman.com/downloads/examples/safari-audio-issue/safari-issue.html

   Do **NOT** click the button

3. Go to http://google.com

4. Go to　http://greggman.com/downloads/examples/safari-audio-issue/safari-issue.html

What happens for me at step 4 is safari doesn't play the music like it did in step 2

I might have to repeat steps 3 and 4. This is in Safari 9.0.3

Safari 9.0.3


If you can't repo try hitting refresh quickly in succession while the music is playing

the URL used in the video above is http://twgljs.org/examples/dynamic-buffers.html but http://greggman.com/downloads/examples/safari-audio-issue/safari-issue.html seems to work for that issue just ask well
Comment 7 Alexey Proskuryakov 2016-02-01 09:51:20 PST 
I could reproduce after a few reloads. Thank you!
