Sound loader issue

[Robert Stevenson]

I usually have no problem with getting this to work but in this case can't seem to get audio buttons to play on export to server (despite .mps files being flagged and actually in the exported "sounds" folder. In this particular case I have an organism image (sponge) with the parts name and function available when the students clicks on the buttons on the image page. The caption shows the name and the soundloader is to play the audio file that gives the function. All of these buttons are part of a group. Curious if that might be my issue. On enterpage I have in the AE

Sounds like pgSoundLoader() is not correctly setup to find your sounds.

In your scenario you need to make sure that your button caption string is properly pointing to a real file location.

So, in pgSoundLoader() you need code something like this for the url_playLIst parameter:

Code: Select all

url_playList = "../sounds/" & caption of self & ".mp3"


... the above parameter setting will resolve, for example, a button caption "canals" to "../sounds/canals.mp3" which will play the audio file "canals.mp3" in your "sounds" folder.

[Robert Stevenson]

Dang! I can't seem to make this work. You're suggesting I need to get rid of the soundloader script for each of the individual buttons on the page and then select everything on the page (well all the buttons at least) and add the url_playlist as you have suggested. My problem may be that the file names don't perfectly correspond to the captions ... which is why I have the soundloader function coded to point to each of the actual sound files in the "sounds" folder. I'm still not sure why that isn't a workable option?

[Clifton]

Whatever you do, pgSoundLoader() needs a path to a real file if it is located in a "sounds" folder. Somewhere along the way you have to prepend the path ( "../sounds/" ) to your name. In addition, you will have to append the file extension of a valid audio file ( ".mp3" ). Unless you set url_playLIst to some valid file path, the function doesn't magically know what you want to do.

If you post the parameters you are using with pgSoundLoader() it would probably be more clear what is going on. But if your sound files exist, I can guarantee that, if they do not play, the function is not getting a valid file reference.

Please remember also that on web servers case senitivity is critical as well as with the JavaScript language. So if you want to play a file that has a path like this "../sounds/mysound.mp3" it will not work if the url_playLIst = "../sounds/mySound.mp3"

[Robert Stevenson]

Which is why this is so frustrating. As far as I can see each button on the page is pointing to the actual .mp3 in the "sounds" folder. I have, for example the button "pores" that is caption less until the student clicks the button. At that point the script is as follows:

Set caption of self to "pores"
url_playList = "../sounds/pore.mp3"

On export the caption, of course shows ... but no sound plays.

[Clifton]

Check the following:

1. Look in the folder tree of the export using Windows Explorer or some other file manager. You should see the following in the export tree:
   [export] > [sounds] > pore.mp3
   
   • If the above is not true then you may need to remove and re-add the sounds folder to your export tree.
2. Try and run the export in Firefox if the problem is occurring in Internet Explorer.
   
   • If the content plays in Firefox but not Internet Explorer, then consider the next item a possible reason for this.
3. Try and put your export on a web server and see if the sound plays.
   
   • If the sound plays when on a web server, then a security restriction is preventing the sound from loading from a hard disk location.
   • OR, your Flash player installation has become corrupted and the Flash player should be reinstalled.
4. Try visiting the Flash player security panel (in any web browser) and verify that web content can play local files. The link to the Flash security control panel is provide below and it looks like the image provided. The option to "Always allow" should be checked to ensure your sound plays from files on your hard drive.

5. If none of the above makes any difference, please zip the tbk and the sounds folder with two or three mp3 files in it and send it to us for review.

[Robert Stevenson]

I have confirmed all of the above ... "pore.mp3" in export sounds folder ... Chrome and Firefox tested negative for the page in question (page 7 of 11) ... all testing has been on a webserver ... Flash is set to "always allow". I would love to send you the files ... where ?

[Clifton]

Thank you for the files.

The problem is your sounds are referenced as "..sounds/name.mp3"
... and should be "../sounds/name.mp3"

That should fix the problem.

[Robert Stevenson]

Wow! That didn't take you long. So much appreciated ... I never would have noticed in a million years.
