Pin Media Player in Quick Settings auf Android
Android hides the media player tile from Quick settings as soon as playback stops or pauses. That is expected behavior, not a bug, because the tile is meant to show active sessions only.
If you want the player to stay visible even when paused, you need to enable a dedicated toggle inside the sound settings. This setting is separate from notification permissions and from any individual music app.
Go to Tap on Settings ➔ Tap on Sound & vibration ➔ Tap on Media ➔ Enable or disable Pin media player. Turning this on keeps the last active media session pinned in Quick settings until you dismiss it manually or start a different session.
This fix only works if the app you use reports its playback state through the standard Android media session, which most streaming and podcast apps do. If a player still does not appear, the app itself may not support this integration, and no system setting will change that.
Keep in mind that pinning does not restart playback or wake the screen. It only keeps the control card in place once something has played at least once during the current session.
