Help for Browser Plug-ins supporting Audio Replay

While Internet Explorer supports audio through its integrated windows media player plug-in, other browsers are more fussy about the use of plug-ins for audio. This page gives some tips for various browsers on how to obtain and configure a plug-in to support embedded audio. These examples have only been tested on a PC.

If you want advice on how to program audio replay in web pages look at How to play sound from a web page.


General advice

It is generally a good idea to install your browser before you install the plug-ins. This way the plug-in installation scripts may detect your browser and install themselves properly. Don't count on this though, sometimes you'll need to configure the plug-in for a particular browser - see below for more information.

If you have installed a new browser and the plug-ins don't work, sometimes you can fix the problem by un-installing and then re-installing the plug-ins.

You can test whether your audio plug-in works by pressing this button!


Installing the Quicktime plug-in

The Quicktime plug-in can be downloaded from http://www.apple.com/quicktime/download/. You may need to be logged on as Administrator to install the software.

Quicktime installation is controlled by a small download manager. In this choose "Custom" installation and choose at least "Quicktime Essentials, Quicktime Capture, and Quicktime Diagnostics". Ignore requests for your e-mail address and registration numbers (unless you want to send them to apple).

At the end of installation you are asked to check the quick-time settings. The important thing here is to check that the WAVE audio file type is being handled by the plug-in. On the "Browser Plug-in" page choose "MIME Settings".

Under the "Audio" section, check that "WAVE audio file" is selected to be handled by the plug-in.

You can also find these from the Quicktime Player application through menu option Edit|Preferences|Quick Time Preferences, then choose "MIME Settings"


FireFox Browser

The FireFox browser can be downloaded from http://www.mozilla.org/products/firefox/.

You can check that a plug-in is enabled to replay WAVE audio files by choosing Tools|Options... then "Downloads" and "Plug-Ins":

But to actually determine the configuration of the plug-ins you should visit the page http://wp.netscape.com/plugins/manager.html. This interrogates your browser to find details about the installed plug-ins. You should check that the QuickTime plug-in is installed, and is set to handle MIME types of "audio/x-wav" and "audio/wav".

Another check on the Plug-in installation is to look at the contents of the "plugins" folder of the Firefox installation folder. You can view this with Windows Explorer:

The files beginning "npqtplugin*.dll" are the QuickTime plug-in modules. If they are not there you may have some success in copying them from the QuickTime/Plugins folder. But un-installation and re-installation of QuickTime may also work.


Mozilla Browser

The Mozilla browser can be downloaded from: /http://www.mozilla.org/products/mozilla1.x/.

You can check that a plug-in is enabled to replay WAVE audio files by choosing Help|About Plug-ins:

If the plug-ins look correct, but replay does not work, try un-installing and then re-installing the quick time plug-in.


Opera Browser

The Opera browser can be downloaded from: http://www.opera.com/download.

You can check that a plug-in is enabled to replay WAVE audio files by choosing Tools|Advanced|Plug-ins.

If the plug-ins look correct, but replay does not work, try un-installing and then re-installing the quick time plug-in.
