Why can't I hear the background music when playing a ppt on my computer but others can?

Why can’t I hear background music when playing ppt on my own computer but I can hear it on other people’s computers

The solution I found on GOOGLE. You have to learn to be self-reliant and don't be lazy.

The inserted music cannot be played when doing PPT. Right-click on the small speaker and select play. It prompts: Unable to play on the specified MCI device

one time,

As a result, some people said to reinstall the sound card driver and reinstall office. My office is streamlined,

I really thought something was wrong here. Reinstalling office still doesn't work.

Looking again, I finally found it.

The specified file cannot be played on the specified MCI device. The solution is:

1 Start-Run Enter regedit to enter the Registry Editor

2 Enter HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI Extensions

Create a new string value "mp3" and change the value to "MPEGVideo"

3 Enter HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI32

Create a new string value "MPEGVideo" and modify the key value to "mciqtz32.dll"

The easiest way:

Windows Media Player\Tools\Options\File Types\MP3 Audio Files (MP3) Check the box in front\Application

Why can’t my ppt background music play after 5 photos?

Open the "Movies and Sounds" option under the "Insert" menu, click "Sound from File", and insert the prepared sound file (preferably MP3 or WAV). At this time, the system will pop up a dialog box asking "Do you want to automatically play sounds when showing slides?" Select [Yes], and a "speaker" icon will appear on the slide.

2. Right-click the "Speaker" icon and select "Custom Animation" in the pop-up shortcut menu.

3. In the "Multimedia Settings" tab of the "Custom Animation" dialog box, the default "While Playing" option is [Pause Slide Show], and the "Stop Playing" option is gray and unselectable. We need to select the [Continue Slide Show] option, then the "Stop Playing" option can be selected. According to your needs, if you want the background music to exist in "X" slides, select "After X slides" in the "Stop Playing" option.

After seeing this, you should understand that if you want to add full background music, you must insert the music file on the first slide and change the "X" after the "Stop Playing" option to the total number of slides. .
