Hi! I see you're using an iPhone with iOS 18.7 and the Pocket Bard app is playing no sound, even though the volume is up both in the app and on the phone. That sounds like something we can troubleshoot together.

First, just to make sure:
- Have you checked that your iPhone is not on silent or Do Not Disturb mode? Sometimes the silent switch can affect app sounds even if volume looks up.
- Also, have you tried closing and reopening the Pocket Bard app? Sometimes that resets sound functions.

If those are good to go, let's try these steps next:

1. Restart your iPhone: A fresh reboot can help reset sound services.

2. Check iPhone Audio Settings:
- Go to Settings > Sounds & Haptics and make sure the Ringer and Alerts volume is turned up.
- Also, check that any Bluetooth audio devices (like headphones or speakers) aren’t connected unintentionally. If so, either disconnect them or change output to the iPhone speaker.

3. App Sound Settings: Since you mentioned the Pocket Bard app volume is up, double-check inside the app for any mute settings or sound output options.

4. Update the App: Check the App Store for any updates to Pocket Bard. Sometimes sound issues are fixed in patches.

5. Reinstall the App: If no updates or sound changes, try deleting Pocket Bard and reinstalling it from the App Store. This can resolve corrupted files affecting audio.

If you’ve tried all that already and it still won’t play sound, there might be an app permission or compatibility quirk related to iOS 18.7. You could also try playing audio in a different app to ensure the phone’s speakers are working.

Would you like me to help you walk through any of these steps? Or could you share if any of these you've already done, so I can suggest the best next steps?
