soundManager onready() or ontimeout() events are ultimately called when start-up completes.
If you're seeing a failure, refer to the below for troubleshooting details for common causes.
Flash 8 or 9 may be required for SoundManager 2 to start, depending on HTML5 support. You are currently using [unknown].
SoundManager 2 must load a flash movie before initialisation can proceed. If you have errors here, check that soundManager.url is correctly defined and that the URL being loaded is correct.
If the Flash movie URL is OK, Flash security or flash blockers are the likely cause. Check the section below.
Have a flash blocker? Check that the SM2 flash movie (below) is loading and is not being blocked.
The Flash Player Global Security Settings Panel is a web-based control panel which allows you to configure Flash security. You will need to add the path of the SoundManager 2 project in order for it to work "offline" (ie., when viewing via file:// or c:/)
Show me how: Adding a "trusted location"
See Flash debug output for more security error details.
HTML page on domain A loading .SWF from domain B: Flash security prevents JS + Flash when a cross-domain XML permission file is not available on domain B, and/or flash movie was not compiled with allowDomain('domainA') or allowDomain('*') - note that the SWF distributed with SM2 does not use this by default; try using the cross-domain version of the SWF, or compile your own which whitelists your own domain(s).
Browser extensions/add-ons like "FlashBlock" and "click to flash" can prevent the .SWF from loading, and this will mean SM2 will time-out and fail waiting for a response from Flash. For development, it's best to whitelist the domain(s) or the .SWF for SM2 to allow it to work.
Have a flash blocker installed? Want to test it? Try the SoundManager 2 Flashblock demo.
Offline viewing conditions and cross-domain security rules will prevent Flash <-> JS communication. See the details of Flash -> JS for information.
Special Firefox Note: Some versions of Firefox (9.0 and newer?) may break JS/Flash in the file:// or offline case even when the path has been whitelisted in the Flash player security settings panel. IE, Chrome, Safari and Opera do not have this issue.
Here, a simple createSound() call is made to test SM2's actual operation. A sound should load and play provided SM2 was able to start successfully.
