In Windows 11, the old Windows Media Player sync experience is not a standard feature in the newer Media Player app. For Windows Media Player synchronization, automatic sync is supported for these device types by default:
- MTP devices
- Mass-storage devices
- Windows CE devices (Windows Media Player 10 Mobile and later)
If using Windows Media Player Legacy, the sync workflow can still appear when a compatible device is recognized. A practical path is:
- Connect the MP3 player.
- Make sure the device is recognized as an MTP or file transfer device.
- Open Windows Media Player Legacy.
- Select tracks, right-click them, and choose Add To > Sync List.
- If the device is recognized, the Sync List appears on the right.
If the sync option does not appear, the device likely is not being recognized in a supported mode. For non-default device types, Windows Media Player synchronization requires the device to meet additional requirements such as advertising the PAP device interface, supporting IMDSPDevice3, setting UseExtendedWmdm to DWORD 1, and implementing specific WMDM interfaces.
On Windows 11 N editions, media synchronization can also be unavailable because Windows Portable Devices support and related media features are excluded until the Media Feature Pack is installed.
