*updated September 25, 2013 to note two separate options*
If you have updated to iOS 7, please be aware of some new changes that can affect your ability to hear audio output from our apps (and others). Below, the AmpliTube app is used as an example.
When the app first launches on iOS 7, it will ask you "AmpliTube Would Like to Access the Microphone". Selecting 'OK' will allow you to work as usual.
If you select 'Don't Allow', you will not be able to hear any audio when playing through your iRig, iRig HD, iRig PRO, etc..
If 'Don't Allow' is selected and you hear no output, please see either of the following suggestions to correct this:
1. Open your Settings app and tap on Privacy > Microphone. You will see various audio apps listed, tap the slider to the right of the app and tap it so it appears green in color. This will allow access to the microphone and audio will be heard again.
2. This option involves settings enabling restrictions, which some users may not want to do. If you do not wish to enable restrictions on your device, please see option 1 above to resolve the problem. Open your Settings app and tap on General > Restrictions > tap 'Enable Restrictions' > Microphone > tap 'Allow Changes'.
You will see various audio apps listed, tap the slider to the right of the app and tap it so it appears green in color. This will allow access to the microphone and audio will be heard again.
