Ipad 10th gen 2022 speaker

The iPad10 has only two speakers; when in Landscape orientation, these are on the left and right of the screen.

Have you tried a forced-restart of your iPad when the issue is evident? A restart will often clear an isolated software issue:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

In the problem persists after performing a forced-restart, you might be best advised to visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad. If a fault is confirmed, you’ll be in the best possible place to explore your available options:
