Sample Project

The Google Ads iOS SDK uses UIWebView internally in their GADBannerView class. Ads containing video served to our App using this SDK causes any audio playing in the background to mute even though the HTML 5 video tag used in the example project (attached), specifies muted. Even if the video doesn't contain an audio track the same issue occurs. The upshot is that we have to block ads that contain video resulting in a revenue loss.

To replicate the issue:
- Play some background audio using Spotify, iPlayer Radio etc.
- Run the sample project on an iOS 10 device (may need to change bundle id / team).
- Notice that the background audio mutes (gently).
