If MP3 files are opening on your computer but not on your music system, it could be due to one or more of the following reasons:
File Format Compatibility: The MP3 files may be encoded in a format or bit rate that your music system does not support. Some older or less sophisticated music systems may only support certain bit rates or formats.
File Corruption: The MP3 files might be partially corrupted or incomplete. While your computer can handle minor errors, your music system might not be able to play these files.
File Name or Path: Some music systems have limitations on the length of file names or the use of special characters in file names or folder paths.
Storage Device Compatibility: If you are using a USB drive or other external storage device, the format of the storage device (e.g., FAT32, NTFS) might not be compatible with your music system.
Firmware Issues: The firmware on your music system might be outdated, preventing it from playing certain types of MP3 files. Updating the firmware could resolve the issue.
DRM Protection: If the MP3 files are protected with Digital Rights Management (DRM), your music system may not be able to play them if it does not support DRM.
File Size: Some music systems have limitations on the maximum file size they can play. Large MP3 files might not be recognized by the system.
Checking the compatibility of the file format and bit rate with your music system, renaming the files to remove special characters, or updating the music system’s firmware may help resolve the issue.
