New issue 70496 by kirbso...@gmail.com: embed mp3's autoplay even if
autostart="false" is specified
http://code.google.com/p/chromium/issues/detail?id=70496

Chrome Version : 9.0.597
URLs (if applicable) :
Other browsers tested:
Add OK or FAIL after other browsers where you have tested this issue:
Safari 5: "plugin missing"
Firefox 3.x: "plugin missing"
IE 7/8: works, apparently using WMP plugin

What steps will reproduce the problem?
1. create an mp3 embed

<embed src="file.mp3" autostart="false" />

Load it.

What is the expected result?

It should *not* autoplay said mp3

What happens instead?

It autoplays.

Please provide any additional information below. Attach a screenshot if
possible.

NB that quicktime handles this right, so the typically suggested work
around is to specify type="audio/mpeg"
unfortunately, for users without quicktime installed, it still autoplays.

Cheers!

<embed> paramaters are just passed to the handling plugin; if the plugin
doesn't understand/respect a given attribute, there's nothing Chrome can do
about that.

You'd need to report this to the author of whatever plugin is handling the
<embed>.

I believe this is incorrectly handled by chrome's own internal "default"
plugin. Where should I report this then?

The built-in "Default Plug-in" just provides UI for locating plugins for
content you don't already have plugins for. It doesn't play mp3s.

If right-clicking the embed area doesn't tell you what the plugin is, check
chrome://plugins to figure out what might be handling it.

Thanks for your remarks.

Unfortunately I get the same results after disabling all plugins listed in
chrome://plugins

Perhaps it is a bug that (at least for me) chrome's default music player
appears to be handling embedded music-like files?

demo: http://musicformormons.com/bug/test_autostart.html

(screenshot: http://musicformormons.com/bug/bug.JPG -- note that it's
playing in error )

Perhaps somebody else has seen something like this player before and can
point me in the right direction as to where this plugin is coming from? It
doesn't look like WMP and I've disabled all the other plugins.

Thanks!

Sorry about that; I can indeed reproduce this with your example, and this
is Chrome's built-in media player. (I'm not sure what I did wrong when I
tried to make a test case and didn't see this.)

Given that both WMP and QT respect this attribute, it probably makes sense
for us to respect it as well for embed/object.

I don't think this is something that can really get fixed.. what's
happening is that the embed is falling back to Chromium's HTML5
implementation *which is not a plugin* and therefore doesn't have an
autostart attribute.

Have you tried using <object>? <embed> is more or less deprecated these
days:
