Inbuilt Sound issue

Hello GR787,

Thanks for reaching out to the Apple Support Communities. As I understand your issue, your iPad (2018) Model recognizes that something is plugged into the lightning cable or headphone jack, but nothing is actually plugged in. It sounds like it's stuck in Headphone Mode.

I would start by restarting the iPad: https://support.apple.com/en-us/HT201559

Backup your iPad if it persists: https://support.apple.com/en-us/HT203977

Erase your iPad: https://support.apple.com/en-us/HT201274

Restore your iPad using iTunes if it persists: https://support.apple.com/en-us/HT201252

Contact Apple Support if your troubleshooting does not work.

See if there's any debris in the headphone jack, which might be convincing your iPad headphones are plugged in. If there is, take a toothpick or something (don't use compressed air) and try to dislodge it.

Have you tried plugging headphones in and out a few times? Cleaning the headphones jack? See if there is something in there that can be removed. Have you restarted the iPad or force restarted?
