1. Check file integrity: First, check whether PPT and music files are complete and damaged during copying, transmission or storage. If it is the problem of the file itself, it needs to be re-acquired or repaired.
2. Confirm file format and compatibility: Make sure that the format of PPT and music files is required by the activity and compatible with the software or equipment used. If the format is incorrect or compatibility problems cause playback problems, you need to convert the file to the correct format or use a compatible format.
3. Check the link and path: When copying PPT from another computer to the current computer, if the path changes, you need to save PPT according to the original path or re-link. This ensures that the link and path of the file are correct.
4. Check the equipment and software: confirm whether the equipment or software used can support the playback of PPT and music files. If the equipment or software is incompatible or fails, it is necessary to replace the equipment or upgrade the software.
5. Check the playback settings: Check the playback settings of PPT to ensure that the music files have been correctly added to PPT, and the correct playback mode and order have been set. At the same time, make sure that the volume and synchronous playback settings of music files are correct.
6. Seek help: If the above methods fail to solve the problem, you can seek professional technical support. You can report the problem to the organizer or the person in charge of the event, and contact the IT technician or equipment supplier for help.
In short, we need to find out the problems existing in PPT and music playing in dance competitions, and then take corresponding measures to solve them. If it cannot be solved, seek the help of relevant personnel in time to ensure the smooth progress of the activity.
