Elementary PowerPoint sound plugin shared play
Once I used PowerPoint courseware, you need to insert three sound files: 1.wav (100KB), 2.wav (800KB) and 3.wav (5MB). In courseware, requires two slide 2.wav in respectively used in, and the file in the same 3.wav 2.wav, slides that you want to play at the same time. In the production process, I put three sound file in the same folder as the Sound, the Sound folder and a slide master file Star.ppt Ppt placed in a folder, the production of finished playing everything is normal. So I put the folder Ppt to multimedia classroom teachers machine, where the problem occurs: the sound file plays correctly, but 1.wav sound file 2.wav and 3.wav cannot play. In this issue I had a study and try. (Click to view more software application skills)

Try a: change the size of the linked sound file

Right-click the icon, select 1.wav "edit → sound object", open the "sound options" dialog box appears stating that the file "contained in presentation", and the sound file 2.wav and 3.wav "sound options" in the absolute path of the sound source, and copies the original absolute path on the computer, copy and use the absolute path for the sound source file is not found. This is the sound file plays correctly, but 1.wav sound file 2.wav and 3.wav cannot play.

Perform "Tools → Options" command in the "General" tab of "linked sound file not less than (100) kilobytes" default setting as file 1.wav as 100KB (less than 100KB), therefore, be included in the presentation, while the file is larger than 100KB 3.wav 2.wav, and, of course, be dealt with as a linked file. The author of the linked sound file to set the value to "no less than 50000KB", then reinsert the sound file 2.wav, 3.wav, "sound options" in the display as "contained in presentation", simply Star.ppt file copied to another computer (no need to copy the Sound folder), three sound files will play properly. But in the same picture slide two sound cannot be played.

Try 2: associate a file do the packaging process

Open the file "execution Star.ppt, file → package" command, and then set the Pngsetup.exe and Pres0.ppz files to multimedia classroom teachers machine, unpack after three sound file to play correctly. But because of that computer with PowerPoint software, there is no need for "packaged" and "unpack" toss and packaged file "fertilizer" a lot, because two insert sound files of the same, turned into a filename 2.wav different two files (reference number will appear several files), to the replication process has brought a lot of trouble.

Try three: the sound file and slide file in the same folder

I put three sound files in a folder from the Sound cut and juxtaposed Star.ppt file in the same folder the Ppt Ppt into multimedia classroom, three files play fine. Open three sound "sound options", find the source files continue to be logged with the absolute path, but playback automatically updated, the updated absolute path indicates the sound files are stored in the exact location.

Conclusion: the use of founder author or software such as Dreamweaver, courseware can be used in the main file of sounds, images and other material stored in a folder, you also have a more detailed classification in several child folder, and the primary file have the same parent folder. PowerPoint is not, use the "insert → movies and sounds" method to insert a movie and sound files only and main files together, in play correctly on another computer. When referring to a movie and sound files larger that looked very confused.

To avoid this problem, on another computer on the same computer specified and the original drive letter and folder options, and make it an absolute path and is the same as theoriginal computer, the playback is also very good.
