No audio on iPhone X with iOS 12.1.4 Latest iPad works fine

Unity Engine

I updated my iPhone X to the latest iOS, 12.1.4 and now no matter what I do I get no audio. I had a video playing webm Direct, then I transcoded it, then I dropped audio from video and synced up a wav file and still no audio. My iPad 2018 has the same OS version and works fine. I am at a complete loss. Running Unity 2018.3.0f1. Upgrading to 2018.3.5f1 to see if that helps…

Has anyone else had this issue?

I updated to latest Unity. Also have Vuforia 8 running. Still no audio on iPhone but iPad is just fine.

Did the following as a test.

  • Created a new project with Unity 2018.3.5.f1
  • Switched platform to iOS
  • Created a basic scene with a video playing back on a panel. Video Player, Direct sound, Render Texture, Unlit material applied to panel.
  • Build Xcode project
  • Run on iPad 2018 with OS 12.1.4 and have video and audio.
  • Run on iPhone X with OS 12.1.4 and have video but NO audio…

Any ideas?

Looks like Unity 2018.3.6.f1 solved the issue…

I’m building projects with unity 2018.3.6.f1 and I have the same issue of no sound (iphone 5s)

My version has just been updated to 12.1.4

The only difference is my iphone model.

Anyone else facing this problem?
