Audio Doesn't Work

[Smash99]

Works fine in Simulator, but no audio when testing on a device. On the device, the Mute button makes the beep sound. However, any recordings from the mic are silent. Any ideas?

Thanks for having interest in my translated sample code. When I can use some time for this, I will test it with my devices. (It's long time ago, when I last tested this sample code in actual devices...)

By the way, it's better if you add some more info about your environment, Xcode version, your device name and iOS version, etc.

Sorry for kept you waiting so long.
But I cannot reproduce the same issue with the latest project built with Xcode 10 and tested with my iPhone 7+/iOS 11.4.
And as for now, we have not enough devices to test and I'm afraid we might not be able to check even if you told us your environment. If you find something related, please notify us.
