While playing music with an app other than the Music Player, you may hear overlapping sounds

If you use a music app other than the Music Player on your Walkman®, the (play/pause) button may not operate properly, resulting in both players playing at the same time.

If this occurs, the result may be overlapping audio playback. To avoid this problem, please follow these steps when using an app other than the Music Player:

1. Press the (play/pause) button on the Walkman to pause playback.
2. Open the non-Sony app and operate by pressing Play/Pause.
