Hi! I see that the sound in Vampire Survivors disappeared for you on your iPhone, even though other apps have sound. Let's try to figure this out together.

First, can you please check a couple of quick things with me?

1. Is your iPhone's volume turned up and not muted? Sometimes the side mute switch or volume settings might affect game sound specifically.
2. When you are inside the Vampire Survivors app, do you see any sound/music settings or volume controls in the game’s menu? If yes, could those be muted or turned off by accident?
3. Have you tried restarting the game or even your iPhone to see if the sound comes back?
4. Does the game have the latest update installed from the App Store?

If you confirm the volume and mute settings are okay, and game sounds are enabled but still no sound, we can try a few more steps:

Step-by-step solution:

1. Close Vampire Survivors completely: Double-tap your Home button or swipe up from the bottom and swipe away the game app.
2. Restart your iPhone to clear any temporary issues.
3. Open the game again and test the sound.
4. If still no sound, check iPhone’s Settings > Sounds & Haptics and make sure sound effects volume is up.
5. Also go to Settings > Vampire Survivors (scroll down to app permissions) and ensure it has permission to use sound or media if applicable.
6. As a last resort, try deleting and reinstalling Vampire Survivors. This can fix corrupted app files that might cause sound issues.

If after all these steps the sound issue persists only in Vampire Survivors, it could be a game bug or compatibility problem on your iOS version (26_0_1). In that case, I would recommend contacting the game developers through their official support or their email: [email protected].

Please let me know what you find with these checks and if you'd like me to guide you through any of these steps more closely.

Are you satisfied with the solution I provided?
