If you find that one of your iPad’s microphones sounds muffled after you test it or it has no sound at all, let’s clean them. My favorite way to clean iPad microphones is by using a dry, un-used toothbrush to clean the microphone grill at the bottom of your iPad and the small black dot microphone to the right of the rear-facing camera. Simply slide the toothbrush over the microphones to dislodge any stuck pocket lint, dirt, and dust.

To turn up the volume of an iPad microphone, you should: Click Start?Control Panel?Sounds and Audio Devices. Open the Control Panel?click Sounds, Voices and Audio Devices?click on Sounds and Audio Devices.

To enable microphone on iOS (iPad, iPhone, iPod) go to Settings ? Privacy ? Microphone on your device. Find Yousician on the list and enable microphone access by tapping on the slider (so that it turns green). If the microphone is not working, check instructions from Apple for troubleshooting.

If you have any questions feel free to ask them in the comment section.

Clean The Microphone on the iPad

Also have a look at this step, it is not part of the video:

Get Rid of Any Screen Protectors and Cases

Chances are the new screen protector or the case you have recently installed on your device is interfering with the microphone, and thus making it not work on your device. Remove any of the third-party cases or covers you may have put on your device, as they could be the culprit of the issue. Once the cases are all removed, see if you can use the microphone normally.

Launch the Settings app on your iPhone and navigate to Accessibility - Audio/Visual. Switch off Noise Cancellation toggle. Have a call with a friend and make sure the microphone is functioning properly. If it's still malfunctioning then re-enable the feature and move to the next trick.

Use Quick Start to transfer data to a new iPhone or iPad

QuickStart is not an installable App - but is instead an integral feature of iOS/iPadOS.

where can I get this quick start app to move data from iPad to iPad ?

QuickStart assists in transferring user data, device settings and information about installed Apps - from one device to a new device during initial setup.

It's built in to iPadOS with only one chance to use it right out of the box or after it comes out of a factory reset condition.

QuickStart is a fast and reliable tool to facilitate seamless transfer.

For compatible devices, QuickStart will appear during the first steps of device setup - or after fully resetting an iPad to factory settings.

These support pages should get you started with setup of your new iPad - and the methods of transferring your data from old to new iPad:

Set up your iPhone, iPad or iPod touch – Apple Support

Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support

Use Quick Start to transfer data to a new iPhone, iPad or iPod touch – Apple Support

“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device.

Nothing is moved or removed from the original device.

Alternative

An alternative is to restore either an iCloud or iTunes backup to the new device:
