Hello! I see that you’re experiencing an issue where the Nyan Cat app on your iPhone does not play music, even though your speaker settings are fine. Let’s figure this out together.

First, just to be sure, can you confirm if you’ve checked these:

1. The volume within the Nyan Cat app itself (some apps have their own volume control separate from the device volume).
2. That your iPhone’s silent mode (the switch on the side) is off—some apps mute sound if silent mode is enabled.
3. Whether the app has permission to play sounds (though usually apps have this by default).
4. Restarting the app or your iPhone to clear any temporary glitches.

If you’ve tried these or want me to guide you through, let me know. If not, here’s a simple step-by-step:

1. Open Nyan Cat, start the game, and then press the volume buttons on the side to increase media volume.
2. Make sure the mute switch on your iPhone’s left side is flipped off (no orange showing).
3. Close the app fully: swipe up from the bottom (or double-click home button) and swipe Nyan Cat off.
4. Relaunch the app to see if music plays.
5. Restart your iPhone (hold the side button and volume up/down until the power off slider appears, then slide it; then power on).

If the music still doesn’t play but other sounds in other apps do, it could be a bug in the app or a setting in the app itself.

Have you seen any settings inside Nyan Cat related to music or sound effects? Sometimes apps allow toggling music on/off internally.

Please let me know what you’ve tried or if you see any options inside the app related to sound. We can dig deeper from there.
