A: There actually is a quick and easy fix. It seems that the "mute" button on the side of your iPad has been accidentally turned on (this is common and happens easily). This is the small slider button above the volume switch on the top-right side of the iPad. Make sure it is slid toward the top (the red dot should NOT be visible).
Some users have this slider switch set to "rotate lock". If you've made that change (fyi, you can set the behavior of the side switch in Settings > General > Use Side Switch), then you'll find your mute setting by following these steps:

A: This is an iTunes issue unrelated to your CulinApp application...if you google "iTunes failed to install" you'll see quite a few people complaining about this problem on a wide variety of apps.
The best fix we've found, once you've verified you do have at least 2gb of space available on your iPad, is to install using the App Store app on the iPad itself, rather than syncing with your iTunes PC or Mac.
Note: If you can't find the app under Updates, look under Purchased or select Featured and use the top search box to search for it.
Remember that some apps can be a 2gb download, so it will take some time, depending on the speed of your internet.
If this doesn't solve your problem, we suggest contacting Apple Support as app installation is handled on the Apple side and not by the app itself.
